Abstract: Described is a method of providing an estimate of radiation dose received by a patient during an imaging scan performed by an imaging system. The method includes receiving patient information about the patient, receiving scan data generated during the imaging scan of the patient by the imaging system, creating a virtual dose model of the patient based upon the patient information and the scan data, receiving a selection of a region of interest of the patient, performing a dose simulation on the virtual dose model of the patient or a portion thereof, and determining, based upon an outcome of the dose simulation, an estimate of the radiation dose received within the region of interest. The imaging scan can be a partial imaging scan of a portion of the patient. Also provided is a system and software for carrying out this method.

Abstract: Described are systems and methods for assessing a likelihood of chronic thromboembolic pulmonary hypertension (CTEPH) within a subject patient based upon an analysis of characteristics indicative of chronic thromboembolic pulmonary hypertension within an imaging study of the subject patient. The systems and methods can identify characteristics of one or more anatomical structures within a cardiac region of the subject patient indicative of CTEPH, characteristics of a pulmonary vasculature of the subject patient indicative of CTEPH, and characteristics of a chronic abnormality in a lung of the subject patient indicative of CTEPH. The systems and methods can assess these characteristics to compute the likelihood of CTEPH within the subject patient.
