This invention discloses a method, device, electronic equipment, and medium for assessing the risk of pulmonary embolism. It relies entirely on collected non-invasive objective data and eliminates subjective judgments based on medical history or physician experience, effectively avoiding risk misjudgments caused by subjective variables in the PESI / sPESI model. This ensures the consistency and reliability of the assessment results. The ratio of Qa to Qb is used as the core assessment indicator. This ratio is a continuous variable, eliminating the need for empirical segmentation of parameters and avoiding significant differences in assessment results among patients with similar conditions. The risk level is assessed based on the ratio of Qa to Qb obtained through hemodynamic simulation. The results perfectly match clinical understanding of the severity of pulmonary embolism, improving assessment accuracy. Simultaneously, it reduces patient examination trauma and avoids high equipment and operational costs.

Methods and systems are provided for calibrating a single photon emission computed tomography (SPECT) imaging system. In one example, a collimated line source for calibrating a SPECT system comprises a radioactive material aligned along a central axis of the collimated line source and a plurality of collimator plates arranged perpendicularly around the central axis, the collimator plates including a material that substantially absorbs photons striking the collimator plates.
