Problems solved by technology

[0005] Since the doctor allocates the scanning time of different positions according to the experience value, the allocated scanning time may be inaccurate, which will make the obtained scanning results relatively poor, and the final image of the scanned object will also be relatively poor

Embodiment Construction

[0054] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0055] related technologies, such as Figure 1a As shown, when the PET equipment is working in the continuous mobile scanning mode, the doctor can roughly assign different scanning positions according to the total scanning time and experience value (i.e. Figure 1a scan length in ) scan duration (ie Figure 1a The scanning time in), the corresponding speed of different scanning positions can be calculated automatically. Scanning according to the scanning speed of different positions can obtain the scanning result, and reconstruct the image based on the scanning result to obtain the image of the scanned object. Since the doctor allocates the scanning time of different positions according to the experience value, the allocated scanning ti...

Abstract

The invention provides a scan duration determining method and device, which belongs to the field of medical imaging. The method comprises the steps that a region of interest in a scout image corresponding to a scanned object is acquired, wherein the scout image is acquired by scanning the scanned object within a preset duration; the variance of the radioactivity in the region of interest is determined; and based on the variance and the total scan duration, the optimal scan duration for each scan position of the scanned object is determined. According to the invention, the determined image of the scanned object is great.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a method and device for determining the scanning duration. Background technique [0002] In the field of medicine, PET (positron emission tomography, positron emission tomography) equipment can be used for early diagnosis of human or animal tumors, heart system diseases and nervous system diseases, which can be obtained by scanning the scanned object with PET equipment. images to determine the location of the lesion. [0003] In the prior art, when the PET device scans the object to be scanned, it generally scans in a continuous moving scanning mode. In this mode, the detector of the PET device and the object to be scanned are always in a state of relative motion. When the PET device works in the continuous moving scanning mode, the doctor can roughly allocate the scanning time of different scanning positions according to the total scanning time and experience value, and the corre...
