Problems solved by technology
However, due to the time difference between the images collected by the two, the two sets of images cannot be completely matched.
Moreover, on the one hand, since the patient may take a deep breath and hold his breath when performing a CT or MR scan, the CT image and MR image in this case will inevitably have a large difference from the PET data of a free-breathing scan.
On the other hand, since the patient is very likely to move autonomously during the scanning process of the device, it will also cause the image mismatch between the two
[0003] However, since reconstructing a PET image requires a matching attenuation map, otherwise mismatch artifacts will appear, affecting the image quality

The invention relates to a medical image mismatch detection method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring first modal image data and second modal image data of the multi-modal medical imaging diagnosis equipment; reconstructing the first modal image data and the second modal image data to obtain a first modal image corresponding tothe first modal image data and a second modal image corresponding to the second modal image data; acquiring a first region corresponding to the body in the first modal image and a second region corresponding to the body in the second modal image according to the first modal image and the second modal image; determining a contour difference image caused by body movement according to the first areaand the second area; and determining a mismatch detection result of the first modal image and the second modal image according to the contour difference image. The method can automatically detect whether the medical image is mismatched or not.
Description
technical field [0001] The present application relates to the field of medical technology, in particular to a medical image mismatch detection method, device, computer equipment and storage medium. Background technique [0002] With the development of medical technology, multi-modal medical imaging diagnostic equipment has emerged, such as PET / CT and PET / MR imaging technologies. The multimodal medical imaging diagnostic equipment can simultaneously obtain the distribution map of radioactive elements in the patient's body and the attenuation map of x-rays by various tissue parts. However, due to the time difference between the images collected by the two, the two sets of images cannot be completely matched. Moreover, on the one hand, because the patient may take a deep breath and hold his breath during CT or MR scanning, the CT image and MR image in this case will inevitably have a large difference from the PET data of a free-breathing scan. On the other hand, since the pat...
