Abstract

The invention relates to a medical imaging device and a method for obtaining images for evaluating the performance thereof. The method comprises the steps of obtaining the effective thickness of a scanning object; obtaining the range of a detector of the medical imaging device; on the basis of the effective thickness of the scanning object and the range of the detector of the medical imaging device, automatically configuring the scanning mode of the medical imaging device; on the basis of the automatically-configured scanning mode, scanning he scanning object to obtain scanning data; on the basis of the scanning data, generating multiple scanning images; on the basis of the multiple scanning images, generating an integrated image, wherein the integrated image is used for evaluating the performance of the medical imaging device. The images used for evaluating the performance of the medical imaging device and obtained through the method do not depend on the die body size, the performanceof complete bay number detectors can be rapidly and conveniently evaluated, and the die body manufacturing cost is saved.

Description

technical field [0001] The present application relates to the field of medical imaging, in particular to a medical imaging device and a method for acquiring images used to evaluate the performance of the medical imaging device. Background technique [0002] In the field of medical diagnosis and treatment today, medical imaging equipment plays an important role, especially CT imaging equipment is one of the most important medical equipment at present. Before CT imaging equipment is used for human body scanning for medical diagnosis, the performance of CT imaging equipment needs to be evaluated in accordance with various regulations. The performance of CT imaging equipment mainly refers to the performance of the detector. Existing performance evaluation methods for CT imaging equipment rely on phantoms that comply with regulations. However, with the emergence of multi-row CT imaging equipment and the increase in the number of detector rows, the size of the phantom has to be i...
