Definitions
- the invention relates to the field of medical imaging. More particularly, the invention relates to a method and a device for measuring fluorescence in a biological tissue.
- a medical imaging system based on the fluorescence of a marker is described for example in the document FR2989876A2. Systems of this type can be further improved in order, in particular, to progress in:
- the method according to the invention further comprises one or the other of the features of claims 2 to 6 considered individually or in combination with one or more others.
- the first optical system comprises a first sensor (which will also be referred to herein as a "fluorescence sensor”) for detecting a fluorescent light emitted on the surface of the biological tissue.
- the second optical system includes a second sensor (also referred to herein as an "optical sensor”) for detecting light in the visible.
- a distance is determined between at least one point of the surface area of the biological tissue and a fixed point in the reference of the probe.
- the distance thus determined is used to focus (using motorized means adapted to move optical elements such as lenses) of the first optical system, on this point of the surface area of the biological tissue.
- focus using motorized means adapted to move optical elements such as lenses
- the first optical system it is necessary to know the distance between this point and the first sensor.
- this first sensor has a fixed and determined position in the probe, it is sufficient, in order to focus the first optical system, to know any distance between this point of the zone on the surface of the biological tissue and a point whose position is precisely known in the reference of the probe.
- the invention can also obtain a quantitative measurement of fluorescence, stable and independent of the distance and orientation of the probe relative to the biological tissue.
- the knowledge of the distance between the fluorescence-emitting zone and the probe makes it possible to determine, from the quantity of light detected by the fluorescence sensor, and that emitted by the light source linked to the sensor, that issued at the level of the biological tissue.
- a practitioner has the elements to correctly interpret images and make relevant decisions in real time.
- the image collected in the visible is essentially necessary to give information on the context, the topology of the area observed, etc. While the fluorescence image gives the essential information.
- An optical sensor of relatively small size may be sufficient to collect light in the visible, which allows to keep a probe having dimensions small enough to be easily manipulated.
- the invention is a device for measuring the fluorescence on an area on the surface of a biological tissue, according to claim 7.
- This device also comprises one or other of the features of claims 8 to 18, each in isolation or in combination with one or more others.
- Figure 1 is a diagram showing an exemplary embodiment of a probe of a device according to the invention.
- Figure 2 is another diagram, according to a plane passing through the optical axes of the optical systems of the probe illustrated in Figure 1;
- FIG. 3 shows schematically an exemplary embodiment of a device according to the invention incorporating a probe such as that illustrated in Figures 1 and 2;
- FIG. 4 shows schematically different steps of a method according to the invention;
- FIGS. 5 and 6 show fluorescence images obtained from the probe of the device illustrated in FIGS. 1 and 2;
- FIG. 7 is a diagram illustrating the variation, as a function of the observation distance, of the ratio of the fluorescence intensity calculated from measurements made with a device such as that illustrated in FIG. than the variation, as a function of the observation distance, of a ratio of the square of observation distances.
- the device according to the invention comprises a probe 1, itself comprising a housing 2 in which are housed a light source 3 adapted to emitting excitation radiation, a lighting source 4, two marking sources 5, 6, and a first 7 and a second 8 optical systems (see Figures 1 and 2).
- the device according to the invention also comprises display means 50 and calculations 60.
- the display means 50 make it possible to simultaneously display images in the visible I and F fluorescence, an area of a biological tissue to observe 9.
- the excitation light source 3 is fixed in the reference of the probe. It is intended to excite at least one fluorescent marker located in the area of biological tissue to be observed illuminated by the illumination source 4.
- the wavelength of the radiation of the excitation source 3 is essentially or at least roughly between 630 and 820 nanometers.
- the fluorescent marker is for example indocyanine green, or ICG (acronym meaning IndoCyanine Green).
- the spectral band of excitation of this marker is essentially or approximately between 750 and 820 nanometers and its spectral band of fluorescence is essentially or approximately between 800 and 870 nanometers.
- the first optical system 7 comprises various optical components (focusing lenses, filters, etc.) organized along a first optical axis A and a fluorescence image sensor 10 (also called “fluorescence sensor” or “first sensor In this document), itself including a matrix photodetector.
- This photo-detector is sensitive in the infrared.
- the surface of this photo-detector is the bigger possible. For example, its diagonal dimension is greater than one inch.
- the larger the surface of the photodetector the more photodetector can capture photons, and therefore the better the sensitivity of the fluorescence sensor 10.
- the dimensions of the photodetector must be limited. to keep a probe 1 easy to handle (for example, a probe 1 having a front diameter of less than or equal to 80mm is a good compromise).
- the second optical system 8 also comprises various optical components (focusing lenses, etc.) organized along a second optical axis B and an image sensor 11 in the visible spectrum, itself comprising a matrix photodetector.
- This sensor 11 also called “optical sensor” or “second sensor” in this document
- This photo-detector is chosen to have the smallest possible surface, while maintaining a good image quality with visible light available. For example, its diagonal dimension is less than one third of an inch and is preferably less than half an inch.
- first A and second B optical axes intersect. They are then in the same plane P of space.
- the optical sensor 11 makes it possible to produce a color image of the area of biological tissue to be observed 9 (but it is also possible to use an optical sensor 11 making it possible to produce an image in the spectrum of light visible, in black and white, or grayscale, from area 9).
- the two marking sources 5, 6 are, for example, laser sources that emit for example with a wavelength in the green, essentially between 520 and 532 nanometers.
- the wavelength of these marking sources 5, 6 is visible by the optical sensor 11, but not by the fluorescence sensor 10. Otherwise said, advantageously, the marking light sources 5, 6 do not excite the fluorescence detected by the fluorescence sensor 10.
- the two sources of marking 5, 6 each illuminate a plane P or P 'of the space (in fact, it is rather a sector located in a plane P or P', but later on use the term "plan” for the sake of simplification).
- the plane P projected by one of the 6 marking sources 5, 6 corresponds to the plane P of the space in which are located the first A and second B optical axes.
- the plane P 'projected by the other marking source 5 then corresponds to a plane perpendicular to the plane of the space in which the first A and the second B optical axes are located, and it also comprises the first optical axis A.
- the intersection of the two planes P, P 'projected by the two marking sources thus corresponds to the first optical axis A.
- the intersection of these two planes P, P' projects at a point O, on the area of biological tissue to be observed 9.
- This point O is placed on the optical axis of the first optical system A. It is fixed for the fluorescence sensor 10, regardless of the orientation and the position of the probe 1 with respect to this zone 9. On the other hand, the point O can be mobile for the optical sensor 11 if the probe is moved.
- the projection on the biological zone to be observed 9 of the second optical axis B corresponds to a fixed point M for the optical sensor 11 and its position on the image I made using the optical sensor
- the position of the point O seen by the optical sensor 11, with respect to the position of the point M seen by the optical sensor 11, corresponds to a distance e.
- This distance e variable as a function of the distance between the point O and a fixed point in the reference of the probe, makes it possible to determine the distance between the optical sensor 11 and the surface on which this mobile point O projects.
- the determination, by the computing means 60, of this distance e also makes it possible to know the distance between the fluorescence sensor 10 and the point O on the surface of the area of biological tissue to be observed 9.
- an excitation light source is provided whose intensity is controlled as a function of the distance between at least one point of the surface area of the biological tissue and the fixed point in the reference of the probe.
- the area of biological tissue to be observed 9 is illuminated with the excitation light source 3, the illumination source 4 and the two marking sources 5, 6 (Step 100);
- Step 200 the position O, in the field detected by the optical sensor, of the cross formed by the intersection of the two planes P, P 'projected by the marking sources 5, 6 is determined in real time by means of a image processing algorithm (Step 200); - this position of the cross is used for, in real time:
- Step 300 calculating the distance between a fixed point in the reference of the probe 1 and the surface of the biological tissue zone to be observed 9 (Step 300).
- Step 400 o focusing the first optical system 7 on the surface of the biological tissue area to be observed 9 (Step 400);
- the intensity of the fluorescence signal is calculated as a function of the distance calculated previously, between a fixed point in the reference of the probe 1 and the surface of the biological tissue zone to be observed 9 (Step 500).
- the determination, in the image I captured by the optical sensor 11, of the position of the cross is achieved, for example, by adaptive thresholding of the colorimetric components.
- the calculation of the distance between the fixed point in the reference of the probe 1 and the surface of the biological tissue zone to be observed 9 is carried out according to a conventional telemetry method or by means of a prior calibration of the probe 1 giving the distance between a fixed point in the reference of the probe (this point being located on the porthole of the probe 1 for example) and the surface of the biological tissue zone to be observed 9, as a function of the movement of the cross in the image I captured by the optical sensor 11.
- the distance between the fluorescence sensor 10 and the surface of the biological tissue area to be observed 9 can be determined by other methods that do not rely on an image analysis method.
- the flight time method disclosed in document FR3036195A1, incorporated by reference, may be used.
- the principle of determining the intensity of the fluorescence signal as a function of the distance between the fluorescence sensor 10 and the surface of the biological tissue area to be observed 9 is as follows.
- the fluorescence signal received by the fluorescence sensor 10 depends directly on the excitation irradiance received by the biological tissue to be observed 9 (it also depends on the exposure time considered constant initially). However, for a constant excitation power, when the excitation light source 3 is on the probe 1, this irradiance varies with the distance between the biological tissue to be observed 9 and this source Thus, knowing in real time this distance it is possible to normalize the value of the intensity of the fluorescence measured with respect to this distance.
- the irradiance received on an area of biological tissue to be observed 9 varies inversely proportional to the square of the distance that separates it from the excitation light source 3.
- the intensity of the fluorescence signal emitted by this area is proportional to the amount of excitation light reaching that area per unit of time.
- the intensity of the detected fluorescence signal also varies inversely proportional to the square of the distance d between the emitting zone and the fluorescence 12 of the excitation light source 3:
- A is a coefficient which takes into account the excitation power of the excitation light source 3, the absorption and emission power of the biological tissue to be observed, the sensitivity of the fluorescence sensor 10 in the length range of the fluorescent emission and the concentration of fluorescent marker (fluorophore) in the area of the biological tissue to be observed.
- step c displaying an image for which the intensity of the fluorescence corresponding to each pixel has been corrected in step c).
- the image F is obtained from a plane surface.
- FIG. 1a represents an image of a scene comprising emitters 13 of a fluorescence signal (this image, which is chosen for its simplicity of obtaining the corresponding scene, does not correspond to a zone of biological tissue, but the The process explained here is in all respects analogous to what it would be to exploit an image of biological tissue.
- This image is made from the fluorescence signal detected by the fluorescence sensor 10, placing the probe 1 at a distance of 115mm from the emitters 13 of the florescence signal.
- the image Ib represents the same scene, by placing the probe 1 at a distance of 190mm from the emitters 13 of the florescence signal.
- the image also represents the same scene, placing the probe 1 at a distance of 262mm emitters 13 of the florescence signal.
- FIG. 7 shows that the curve follows the same trend as the curve in
- the image Id of FIG. 6 corresponds to the fluorescence signal emitters 13 observed with the probe 1 at an observation distance of 115 mm.
- the image If of FIG. 6 corresponds to the same fluorescence signal emitters 13 observed with the probe 1 at an observation distance di equal to 163 mm.
- the image of the figure corresponds to the image Id, realized with a distance of observation of
- this method makes it possible to modulate, on display, the intensity of the detected fluorescence signal as a function of the distance determined between at least the point of the surface area of a biological tissue and the probe 1.
- the device according to the invention may comprise two sources of laser marking which make it possible to form a cross-sight. It is then possible to detect the fluorescence signal in the center of this cross to obtain a quantitative value of this signal: Fluorescence signal re pt ref) to a reference distance d ref and a reference exposure time t re f. [045] Thus, from a value of the fluorescence signal detected under particular conditions of use (at a distance d t and during an exposure time it is possible to calculate the value of the intensity of the signal of fluorescence Fluorescence signal (d e ⁇ , which would have been in a reference condition ⁇ dt t re ):
