Abstract

The application provides a medical image reconstruction method, a medical image display method, medical image display equipment and a medical image reconstruction system, and relates to the technical field of medical images. The method comprises the steps of reconstructing a medical image file based on a first imaging parameter, acquiring a second imaging parameter, and generating a parameter description file only when the second imaging parameter is determined to be different from a parameter value of a first imaging parameter display parameter only. Because only the parameter description file is generated when the second imaging parameter is different from the first imaging parameter only in displaying the parameter values, and a plurality of medical image files under the second imaging parameter are not required to be generated, the imaging pressure of the medical image equipment can be effectively reduced.
