The invention discloses an image artifact automatic correction method, a system and a device and a storage medium. The method is implemented in the medical imaging device. The method comprises the following steps: acquiring a first reconstructed image of a target object; determining whether the first reconstructed image contains artifacts or not; and in response to the fact that the first reconstructed image contains artifacts, determining a target reconstructed image of the target object through at least one iteration. Wherein each iteration comprises the following steps: acquiring a second reconstructed image of the target object in the current iteration round by executing an artifact removal operation; determining whether the second reconstructed image contains artifacts or not; in response to the fact that the second reconstructed image does not contain artifacts or the contained artifacts meet a preset tolerance condition, acquiring original scanning data of the target object, anddetermining the target reconstructed image through artifact removal operation based on the original scanning data; and in response to the fact that the artifact contained in the second reconstructedimage does not meet the preset tolerance condition, executing the next round of iteration.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular to an image artifact automatic correction method, system, device and storage medium. Background technique [0002] In recent years, with the development of medical imaging, imaging technology has become more and more mature, and medical imaging equipment (such as CT equipment) has become more and more widely used, for example, disease screening. [0003] At present, there are more or less artifacts in medical images generated by scanning medical imaging equipment. The existence of artifacts may mislead the diagnosis of diseases based on medical images, resulting in missed or misdiagnosed cases. Therefore, it is hoped that a method for quickly removing artifacts can be provided to quickly detect and remove artifacts in medical images, so as to ensure that the artifacts in the generated medical images are as small as possible or even non-existent, and improve th...
