Inclusion criteria
Inclusion criteria: The research subjects of this study consist of two levels: 1. The participating doctors; 2. Evaluate the cases (images) used. 1. Criteria for the test physician (1) Hold a valid physician's practice certificate, with the scope of practice including medical imaging diagnosis. (2) Divided into two groups based on professional experience: • Junior group: Independently engaged in echocardiographic diagnosis and report writing for no more than 5 years. • Senior Group: Independently engaged in echocardiographic diagnosis and report writing for at least 10 years, and holding the title of attending physician or above. (3) Currently, no less than 10 echocardiogram reports are routinely completed every week. (4) Participate voluntarily and sign a written informed consent form. (5) Be proficient in operating computers and ensure access to the research systems deployed within the institute during the research period. 2. Criteria for evaluating cases (images) The static images and dynamic cycles of echocardiography used in this study must meet the following requirements: (1) The image quality is qualified and can meet the basic requirements for clinical diagnosis (clear display of key areas such as heart cavity structure and valves). (2) The images include conventional sections (such as the long axis, short axis, apical four-chamber heart, two-chamber heart, etc. of the left ventricle beside the sternum) and necessary measurement data. (3) The case diagnosis should have a wide coverage and include: Cases that are normal or have no obvious structural abnormalities
Exclusion criteria
Exclusion criteria: Exclusion criteria for the participating doctors Doctors who meet any of the following conditions will be excluded: (1) Physicians who are not specialized in echocardiography or whose daily work does not involve cardiac ultrasound diagnosis. (2) Personnel who directly participated in the algorithm development or training data annotation of the AI system verified in this study. (3) There is a direct conflict of interest with the research project funder that may affect the objectivity of the results. (4) Those who plan to be away for a long time during the research period and are unable to complete all the evaluated cases. 2. Evaluate the exclusion criteria for cases (images) Case images that meet any of the following conditions will not be accepted: (1) The image quality is extremely poor, making it impossible to conduct reliable visual assessment. (2) The patient information is not desensitized thoroughly, posing a risk of privacy leakage. (3) The diagnosis of the case is not clear. Even after review by the expert committee, no consensus can be reached to determine the "gold standard".
