摘要:
A system including initialization, imaging, alignment, processing, and setting modules. The initialization module obtains patient parameters for a patient and procedure and surgeon parameters. The initialization module selects first settings for an x-ray source based on the patient, procedure, and surgeon parameters. The image module obtains a first sample set of images of a region-of-interest of the patient and a master sample set of images. The first sample set was acquired as a result of the x-ray source operating according to the first settings. The alignment module aligns the first sample set to the master sample set. The processing module processes pixel data corresponding to a result of the alignment based on a pixel parameter or one of the patient parameters. The setting module adjusts the first settings to provide updated settings. X-ray dosage associated with the updated settings is less than x-ray dosage associated with the first settings.
