Systems and methods for identifying medical image acquisition parameters

摘要

Systems and methods are disclosed for identifying image acquisition parameters. One method includes receiving a patient data set including one or more reconstructions, one or more preliminary scans or patient information, and one or more acquisition parameters; computing one or more patient characteristics based on one or both of one or more preliminary scans and the patient information; computing one or more image characteristics associated with the one or more reconstructions; grouping the patient data set with one or more other patient data sets using the one or more patient characteristics; and identifying one or more image acquisition parameters suitable for the patient data set using the one or more image characteristics, the grouping of the patient data set with one or more other patient data sets, or a combination thereof.

主权项

1. A computer-implemented method of identifying image acquisition parameters, the method comprising:
receiving a preliminary medical scan or reconstruction of a patient anatomy; computing one or more patient characteristics and one or more first image characteristics of the received preliminary medical scan or reconstruction based on a scan type, the scan type including scout scan, calcium scan, partial acquisition scan, or contrast timing scan; receiving a second medical scan of the patient anatomy, the second medical scan including a reconstructed medical image defined, at least in part, by vessel segments or by vessel centerlines of the patient anatomy; determining one or more local image regions of the received second medical scan of the patient anatomy; computing one or more second image characteristics for a determined local image region of the received second medical scan, the one or more second image characteristics including global and local image quality scores computed based on the scan type of the received preliminary medical scan or reconstruction; determining an image quality score based on the patient characteristics, the computed first image characteristics, and the computed second image characteristics; and identifying one or more recommended image acquisition parameters or a prediction of image quality for a new image based on the determined image quality score.
