Description
Technical field
This utility model relates to nuclear medicine image equipment, particularly the special gammacamera of a kind of mammary gland based on CZT.
Background technology
Nuclear medicine image is based on the inside and outside radioactivity difference of internal organs and the inner local radiation gender gap of internal organs, and internal organs are directly relevant with the aggregate amount of developer with height radioactive in pathological changes, the number of aggregate amount depends on again the factors such as blood flow, cell function, cell quantity, metabolic rate and excretion drain, therefore, nuclear medicine image can not only show the position of internal organs and pathological changes, form and size, the more important thing is the information simultaneously provided about aspects such as blood flow, function and metabolism.
Blood flow, function and Developmental and Metabolic Disorder are usually the early changes of disease, can appear at before morphosis changes, therefore nuclear medicine image often contributes to the early diagnosis of disease, and be widely used in internal organs and functional status and the disease essence research at molecular level.
Detector is the most important ingredient of nuclear medicine facility, and scintillation crystal is the core of conventional detectors.For gamma-ray detection, now widely used technology is, adopt sodium iodide,crystal (NaI(Tl)), the scintillation crystal such as bismuth germanium oxide (BGO), yttrium luetcium silicate (LYSO), gamma-rays is changed into fluorescence (purple light or ultraviolet), then use photomultiplier tube (PMT) optical signal to be changed into the signal of telecommunication of imaging needs.But, through repeatedly transforming, processing between gamma-rays to the signal of telecommunication, there is scattering in fluorescence in crystal, causes the loss of bulk information, also reduce the degree of accuracy to gamma-rays location ex vivo simultaneously, limit the spatial resolution of nuclear medicine facility, sensitivity.Therefore, tradition has obvious defect based on the nuclear medicine facility of scintillation crystal, PMT, subsequent conditioning circuit basic technology.
At present, along with CZT(tellurium zinc cadmium) research of semi-conducting material is deeply, gamma-rays is directly converted into the signal of telecommunication by CZT semiconductor detector, without the transition of fluorescence, also do not need PMT, volume reduces, directly can obtain the position signalling from detector photon and energy, and bring a series of excellent properties thus, as high in energy resolution, spatial resolution is high, detection efficient is high, sensitivity is good, etc.The application of CZT semiconductor detector substantially increases certainty of measurement, improves picture quality, shortens imaging time, decreases patient injection dosage, is specially adapted to the early diagnosis and therapy of different parts cancer.
Needing with patient during conventional gamma cameras capable mammary gland scintigraphy prostrate for the custom-designed flat board of mammary gland video picture allowing two mammary gland naturally droop, obtaining the lateral projection of every side mammary gland.Patient lies on the back bit slice before acquisition one frame subsequently.Because the probe of conventional gamma cameras is comparatively large, be generally the large visual field of 40 ~ 60cm, the scope that can detect is large, but not easily presses close to body surface, far away apart from target spot, detects efficiency (γ counting rate) and reduces, have impact on its resolution and sensitivity.And when getting the anteposition video picture of dorsal position row mammary gland, mammary gland is overlapping with thoracic wall and thorax abdomen organ (heart and liver etc.), target organ and background contrast is reduced, affects detecting breast lesion.Therefore needing to develop a kind of gammacamera with high-resolution and low coverage newly with what improve the resolution of mammary gland video picture and optimization mammary gland video picture detects efficiency.
Utility model content
The purpose of this utility model is to provide the special gammacamera of a kind of mammary gland based on CZT, and the first, adopt CZT detector, spatial resolution, energy resolution, temporal resolution, detection efficient, sensitivity all have clear superiority.The second, below CZT detector, be provided with a support panel.Support panel one is that prevent the artificial movement of mammary gland, the thickness of breast is reduced, and pathological changes point is more easily detected device and detects in order to fix and to extrude breast slightly.Two is can wardrobe Caudad and the position video picture of middle side when mammary gland to contact with CZT detector and accompanies slight compression, increases to contrast and the resolution of picture simultaneously, optimizes being positioned in the middle of mammary gland and the detecting of deep.Three is have shielding action to gamma-rays, adds the multiformity of superset, the visual field only can be confined to mammary gland, eliminates the image of (outside) above division board, reduces the scattering interference from closing on organ.4th, probe erecting of panel is on elevating mechanism, and pressure when elevating mechanism presses down is 450 ~ 600g, so feel more comfortable when patient checks.5th, the probe (check-out console) of the special gammacamera of mammary gland is adjustable, not only can oscilaltion, can also around mammary gland target spot all-direction rotation, to select different position to study.
For achieving the above object, the special gammacamera of mammary gland based on CZT provided by the utility model, comprise mainframe box, maintenance cabinet door, workbench, castor, electric pushrod, CZT detector, cantilever design, display bracket and display, maintenance cabinet door is provided with outside mainframe box, side, mainframe box top is provided with workbench, and opposite side is provided with cantilever design; Described workbench is provided with display bracket, is provided with display above display bracket, mainframe box has foot wheel; Also comprise riser guide, riser guide is installed above cantilever design, and the bottom of riser guide is provided with supporting plane, and the top of supporting plane is provided with CZT detector, and described CZT detector is slidably arranged on riser guide.
