Description

Technical Field

[0001] The present invention relates to the field of medical information, and in particular to a method and system for dynamically prompting MR artifacts in a diagnosis report system. Background Art

[0002] In daily MR scanning, due to the technical characteristics and technical limitations of MR equipment, some artifacts will be systematically generated on patient images in certain specific cases. These artifacts are likely to have a serious impact on inexperienced diagnostic doctors. Generally speaking, the way doctors eliminate the diagnostic risks brought by artifacts is through active learning, as well as careful observation and analysis at work. The active learning method relies heavily on the doctor's personal learning ability and cannot be simply educated and passed on. If a doctor has been focusing on a certain field for a long time, he / she is usually familiar with the artifacts in this field. Once he / she is involved in other less familiar fields, he / she may still be affected by artifacts that are difficult to detect, thereby affecting the quality of diagnosis or causing confusion and reducing efficiency.

[0003] If there is a personalized reminder method that dynamically indicates the type of artifact that may occur based on the patient's scan situation and displays typical artifacts, the risk can be systematically reduced. Summary of the invention

[0004] In view of this, the main purpose of the present invention is to provide a method and system for dynamically prompting MR artifacts in a diagnostic report system. In view of the fact that imaging doctors are not familiar with MR artifacts, which may affect the diagnosis quality and efficiency, based on the analysis of DICOM image sequence characteristics, possible artifact types and examples of typical artifacts are dynamically given, so as to reduce the difficulty of learning for diagnostic doctors and improve the diagnosis quality and efficiency.
