Description
Technical field
The present invention relates to clinical medicine 3 Dimension Image Technique field, particularly relate to a kind of UWB 3-D imaging system for medical science.
Background technology
Modern medicine imaging technique, as a kind of detection method of non-intrusion type, by providing the 26S Proteasome Structure and Function image of tissue, organ for medical diagnosis, plays more and more important role in human lives.
At present, medical imaging technology is generally divided into structure imaging technology and the large class of functional imaging technology two.Common structure imaging technology comprises X ray CT imaging technique (X-ray Computed Tomography, XCT), mr imaging technique (Magnetic Resonance Imaging, MRI), ultra sonic imaging (UltrasoundImaging) etc.Common functional imaging technology comprises Functional MRI (Functional MagneticResonance Imaging, FMRI), single photon emission computerized tomography technology (Single-PhotonEmission Computed To-mography, SPECT), positron emission tomography (PositronEmission Tomography, PET) and optical tomography (Optical Tomography) etc.XCT and MRI can provide structural information, but can not be used for pathological diagnosis; SPECT, PET and optical image technology can provide cell function and metabolic change, but accurately cannot locate pathological tissues; Ultrasonic technology is substantially harmless, but between the less different tissues of sound impedance difference, DeGrain is distinguished in imaging, and ultrasound wave only provides two-dimensional imaging at present, and 3 Dimension Image Technique is still immature.Above, except ultrasonic technique, all the other technological means can radiation emitting ray, is harmful to, repeatedly repeatedly irradiates, have the risk causing human body cell canceration the person.
UWB medical 3 D imaging technique, UWB Microwave electromagnetic irradiation belongs to Non-ionizing radiation, in safe-dosaging limits, substantially harmless to human body.Secondly, UWB microwave imaging can obtain the important dielectric parameter characteristic of biological tissue.Easily can distinguish blood, the moisture between cancerous issue and normal structure, practical function imaging.Moreover UWB medical imaging is little in media interior decay, and penetrance is good, relies on the ELECTROMAGNETIC REFLECTION to discontinuity medium, effect is distinguished to the imaging of tissue and is better than ultrasonic imaging.Solving other microwave Imaging Technique only can one dimension, two-dimensional imaging, and the deficiency of DeGrain is distinguished in harmful and imaging.
Summary of the invention
The object of the invention is to overcome that existing imaging technique is harmful, imaging distinguishes DeGrain and only can one dimension, the deficiency of two-dimensional imaging, provides a kind of UWB medical 3 D imaging system.
The technical scheme realizing the object of the invention is as follows:
A kind of UWB medical 3 D imaging system, comprise transmitting-receiving array antenna, described transmitting-receiving array antenna connects receives and dispatches array element corresponding connection, receiving element in described transmitting-receiving array element passes the signal along to A/D sampling unit, and the instruction received from time series stereodata unit, transmitter unit in described transmitting-receiving array element receives the instruction from time series stereodata unit, also comprise SAR data image forming process unit, described SAR data image forming process unit receives the signal that A/D sampling unit sends, and be delivered to user's display and control terminal, described user's display and control terminal sends instructions to SAR data image forming process unit and time series stereodata unit, instruction from user's display and control terminal is sent to SERVO CONTROL and driver element by time series stereodata unit, described SERVO CONTROL and driver element gated sweep frame,
Also comprise described scanning gantry and comprise inner core and urceolus, described urceolus centrally can carry out 360 degree of rotations by axle, and described transmitting-receiving array antenna is connected on urceolus.
After adopting said structure, the invention has the beneficial effects as follows: can realize 3 d function imaging, successful is distinguished in imaging, harmless, is applicable to clinical medical imaging technique.
