Performance test method for medical computed tomography equipment

Abstract

The invention relates to a performance test method for medical computed tomography equipment, which comprises a computer and a CT experimental instrument, and the CT experimental instrument comprises an X-ray tube, an X-ray detector module, a reconstruction unit module, a position alignment unit module, a differential body data generation unit module and a display image generation unit module, the X-ray detector module is used for detecting X-rays penetrating through a detected body and generating projection data, the reconstruction unit module can generate a plurality of original body data at different imaging moments according to the projection data, the differential body data generation unit module adopts the plurality of original body data after the alignment, and performs differential processing between the original body data at different imaging moments, and obtains the differential body data corresponding to the different imaging moments. In short, according to the technical scheme, an excellent optimization scheme is utilized, and performance of medical computed tomography equipment can be well tested.

Description

Technical field [0001] The present invention relates to the field of medical equipment performance testing, and more particularly to a performance test method for medical computers tomography equipment. Background technique [0002] CT (Computed Tomography), is scanning a layer around the human body; measured data from each point in this level, then utilizes the high-speed calculation capability of the electronic computer and the principle of image reconstruction, the cross-section of this level is obtained. Image or coronary image; the earliest understanding of ray imaging is starting from X-rays; the development and application of medical X-ray machine imaging technology has been nearly a hundred years of history, it is the physical properties and biological effects of X-rays The human organ tissue is checked; because the ordinary X-ray machine can only project the internal morphology of the human body on the two-dimensional plane, it will cause the imaging organ and bone to ov...
