The invention relates to a medical image acquisition method and device, equipment and a computer readable storage medium. The method comprises the following steps: acquiring a medical image in real time; extracting gradient direction histogram features of the medical image; inputting the gradient direction histogram features of the medical image into a completely trained shallow machine learning model to obtain a classification result, the classification result being used for representing whether artifacts in the medical image influence identification of tissue features or not; and under the condition that the classification result shows that the artifacts in the medical image influence the identification of the tissue features, carrying out medical image acquisition again. According to the invention, the method solves a problem that a medical imaging system cannot recognize the image quality, achieves the recognition of the image quality of a medical image, achieves the automatic image re-scanning when the image quality is not enough, and effectively reduces the workload of a doctor.
Description
technical field [0001] The present invention relates to the field of medical image processing, in particular to a medical image acquisition method, device, equipment and computer-readable storage medium. Background technique [0002] In medical imaging systems, image quality depends on many factors, such as spatial resolution, tissue contrast, signal-to-noise ratio, contrast-to-noise ratio, image defects, etc. Among them, in scanning, the image quality of motion artifacts caused by the subject's movement such as breathing, heartbeat, and posture cannot be improved through optimization of hardware and scanning parameters, and poor image quality cannot meet Clinical diagnostic requirements. [0003] In order to present better image quality, after image reconstruction, physicians need to manually retrieve and observe the reconstructed images, and evaluate the integrity of the information contained in the images, so as to determine whether these images are reliable before data ...
