The development enhancement device performs collection on a SPECT device development image on the same node of the heart beating, performs superposition on the collected image through using multiple-superposed image processing technology, enhances the display strength of the focal zone of the heart, increases the acutance of the rim of the focal zone of the heart, and improves the imaging quality of the hypoxia survived cardiac muscle.
Description
Technical field
The present invention relates to image processing equipment, especially, be that the development of a kind of weary oxygen survival myocardium strengthens equipment.
Background technology
Along with carrying out of arteria coronaria Reconstruction, the problem that whether there is survival myocardium is increasingly subject to the concern of people, and how to detect survival myocardium and be just particularly important, if patients with coronary heart disease can be identified survival myocardium in time, enforcement revascularization as early as possible, recover regional myocardial blood supply, then can improve contractile function and the prognosis of patient's cardiac muscle. Can the patient clarified a diagnosis as myocardial infarction be benefited from revascularization, and estimation prognosis, avoid causing unnecessary wound, Economy type medicine expense etc. to patient in be respectively provided with significance. Survival myocardium in coronary heart disease supplies angle from oxygen, it is possible to is considered as weary oxygen but the cardiac muscular tissue of survival, therefore, it can utilize anoxia developing agent that survival myocardium is developed,99mTc-HL91 detects weary oxygen but survival myocardium is worth and is confirmed by many experimentatioies. Research finds,99mTc-HL91 can detect regional myocardial ischemia's anoxia, in global ischemia anoxia model it have also been found that99mTc-HL91 significantly absorbs, and points out its diagnostic value in single and Multivessel disease.
Weary oxygen myocardial imaging is as a kind of brand-new imaging modality, however it remains all deficiencies, and cardiac muscular tissue and background absorb99mTc-HL91 difference gradient is little, and picture quality, not as traditional myocardial imaging, just can show cardiac silhouette, the heart uptake that hypoxic-ischemic degree is different after need to regulating window values or background99mThe problem such as the difference gradient of Tc-HL91 is inconspicuous.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide the development of a kind of weary oxygen survival myocardium and strengthen equipment, the development enhancing equipment of this weary oxygen survival myocardium can greatly improve the image quality of weary oxygen survival myocardium.
The technical solution adopted for the present invention to solve the technical problems is:
The development of this weary oxygen survival myocardium strengthens equipment, including:
Image signal line, SPECT equipment of plugging into development outfan;
Image procossing main frame, connects described image signal line, and catches the process image from described image signal line;
Heart rate inductive head, measures frequency and the intensity of heart rate, and sends the heart rate data after measuring to described image procossing main frame.
The described image procossing main frame data according to described heart rate inductive head, catch the image from SPECT equipment under same heartbeat amplitude, and the image captured is carried out several and overlaps by described image procossing main frame.
As preferably, described heart rate inductive head is cardiotachometer, electric sphygmomanometer or the frequency of heart rate determined according to B ultrasonic image and intensity.
It is an advantage of the current invention that:
Heart size shape on the node of same amplitude of beating is all consistent, utilize the image processing techniques of several coincidences, strengthen the image display intensity of heart focal zone, add the acutance of heart disease range edge, improve the image quality of weary oxygen survival myocardium, it is simple to difference focal area and normal region.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of heart rate waveform.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Consulting Fig. 1, in the present embodiment, the development of this weary oxygen survival myocardium strengthens equipment, including:
Image signal line, SPECT equipment of plugging into development outfan;
Image procossing main frame, connects described image signal line, and catches the process image from described image signal line;
Heart rate inductive head, measures frequency and the intensity of heart rate, and sends the heart rate data after measuring to described image procossing main frame.
The described image procossing main frame data according to described heart rate inductive head, catch the image from SPECT equipment under same heartbeat amplitude, and the image captured is carried out several and overlaps by described image procossing main frame.
The algorithm of several coincidences described can adopt the picture registration general-purpose algorithm in MATLAB.
Described heart rate measurement equipment can adopt traditional cardiotachometer, electric sphygmomanometer or the heartbeat frequency determined according to B ultrasonic image and intensity, beating predictive of heart rate and beating intensity due to heart, therefore the amplitude of heartbeat is can be determined that by heart rate and intensity of beating, when patient at rest, when heartbeat is to same amplitude, its size and shape are basically identical, such as Fig. 1, waveform has reacted the amplitude of heart beating, and waveform rising edge is, with the intersection point of straight line, the point on opportunity gathering the development of SPECT equipment with straight line intersection point or the trailing edge of waveform.
The present invention is used in SPECT equipment in weary oxygen myocardial imaging, it is possible to is effectively improved the development difference of Fa Yang cardiac muscular tissue and normal myocardium tissue, improves development quality.
Described be only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included in protection scope of the present invention.
