Description
Technical field
The present invention relates to a kind of oncotherapy field, particularly the HIFU tumour ablation system.
Background technology
Signal that the magnetic resonance phenomenon produced utilize to be collected and the imaging technique of reconstructed image by MRI (Magnetic Resonance Imaging nuclear magnetic resonance) system.Atomic nucleus in the tissue (contain radix proton or neutron, refer generally to the hydrogen proton) magnetizes in high-intensity magnetic field, after gradient fields gives space orientation, radio-frequency pulse encourages the hydrogen proton of specific precession frequency, and the energy that the hydrogen proton of accepting to encourage discharges in relaxation process is exactly a magnetic resonance signal.By computer magnetic resonance signal is collected, become the black and white GTG by the different switching of signal intensity, opsition dependent is formed two dimension or three-dimensional form, finally forms magnetic resonance image (MRI) (MRI).It has no radiation infringement, the pseudo-shadow of no bone, can many-side, the advantage of multiparameter imaging, soft tissue resolution capability highly.In addition, the parameters relevant with temperature such as the change that utilizes the hydrogen proton resonance frequency among the MRI and spin lattice relaxation time change, and can realize the real-time thermometric of patient's noinvasive.
The building block of MRI system has magnet, spectrometer, patient's bogey, computer analysis software etc.Present employed MRI system, its magnet has two kinds of versions substantially, and a kind of is Open architecture, and a magnetic material respectively is set up and down, and the main stationary magnetic field that is produced is called open MRI systems perpendicular to ground; Another kind of MRI system is a loop configuration, produces main stationary magnetic field at the annular space of a sealing, during use, needs the patient is placed in this annular space.
The element of HIFU (High Intensity Focused Ultrasound high intensity focused ultrasound) tumour ablation system has: HIFU therapy equipment (claiming that again ultrasonic transducer, transducer group, wave source, treatment are first-class), the patient's bogey that is used to carry the patient, computer control software, power generator etc.
Its base therapy principle is to send ultrasonic beam by single or a plurality of ultrasonic transducers, focuses on through media target area in body by the patient is external, makes the ultrasonic sound intensity at focus place, target area reach several thousand even several ten thousand W/cm
2The biological tissue at focus place, target area produces violent mechanical vibration (relaxation) under the synergetic effect of energy, constantly orderly molecular vibration energy is changed into unordered molecular thermalmotion energy, be that mechanical energy is converted to the heat energy in the medium, the temperature of focus place, target area biological tissue was risen to more than 65 ℃ in moment (0.1-ls), make protein that irreversible coagulation necrosis takes place rapidly.Because in the so short time, non-target area is organized and can be subjected to the HIFU damage hardly, " melts " (ablation) purpose of tumor so can reach noinvasive.The tumor therapeuticing method that HIFU tumour ablation treating technology is a kind of noinvasive, have no side effect has become the research focus of international academic community in recent years, and obtains using widely day by day in medical circle.
The HIFU treatment technology has obtained certain clinical practice and has promoted, and has confirmed that China is the country that clinical practice HIFU treatment technology the earliest in the world, quantity is maximum at present, also is to manufacture maximum country of this system product enterprise.
HIFU therapy system in the market all adopts the guiding of B ultrasonic image to implement the location, and system exists fatal defectives such as imaging effect is unintelligible, the tumor-localizing precision is inaccurate, security reliability is relatively poor relatively.In addition, can't carry out noinvasive thermometric, the real-time curative effect assessment of iconography, also become the puzzlement of its clinical practice.
The EXABLTE 2000 type supersonic therapeutic systems that Israel INSIGHTEC company produces adopt the 1.5T magnetic resonance imaging system guiding location of U.S. GE company, and imaging effect is clear, and tumor-localizing is accurate.But because what use is high-field MRI systems, its magnet selects for use superconductor to make, and need use the cooling back installation of liquid nitrogen, makes whole system too expand, operate loaded down with trivial details relatively, the manufacturing cost costliness.And the MRI components of system as directed adopts traditional loop configuration in the HIFU system that they use.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, a kind of brand-new HIFU tumour ablation system is provided.
The objective of the invention is to be achieved through the following technical solutions:
A kind of HIFU tumour ablation system, it comprises at least one HIFU therapy equipment, also comprises an open MRI systems, and the magnetic material of this open MRI systems is provided with perpendicular to ground, and this HIFU therapy equipment is arranged between this magnetic material.
Wherein, the direction of the main stationary magnetic field of this MRI system is parallel to the ground.
Wherein, this HIFU therapy equipment is the overhead HIFU therapy equipment on top between the magnetic material that is located at this open MRI systems.
In addition, this HIFU therapy equipment can also be the underneath type HIFU therapy equipment of bottom between the magnetic material that is located at this open MRI systems.
Perhaps, this HIFU tumour ablation system comprises the underneath type HIFU therapy equipment of bottom between the overhead HIFU therapy equipment on top between the magnetic material that is located at this open MRI systems and the magnetic material that is located at this open MRI systems.
Wherein, the mode of this overhead HIFU therapy equipment employing suspension or support is arranged on the top between this magnetic material.
This underneath type HIFU therapy equipment is carried on the base of this HIFU tumour ablation system.
In addition, this system also comprises patient's bogey, and it links to each other with this base by a lowering or hoisting gear, and links to each other with this underneath type HIFU therapy equipment by encapsulant.
And this patient's bogey is provided with and the corresponding perforate of this underneath type HIFU therapy equipment.
Positive progressive effect of the present invention is: the present invention is an one with MRI technology and HIFU technological incorporation, in a creative way the magnetic material of MRI system is placed up and down from traditional level and changed into perpendicular to the horizontal plane setting, make more convenient installation HIFU therapy equipment between magnetic material, by utilizing MRI system placement technology, the real time temperature change detection techniques, the real-time imaging technology of high-resolution etc., solved the accurate location during puzzlement B ultrasonic formula HIFU system development is used, the noinvasive thermometric, fundamental issues such as curative effect assessment, broken through the development bottleneck of HIFU tumour ablation technology, make the HIFU treatment technology have more safety, reliability, practicality and credibility, and it also has low cost of manufacture, advantage such as easy to use.
