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: An apparatus for suspending air bubbles in a fluid path of a fluid injector system includes an internal chamber having a curved interior wall defined within the housing, an inlet fluid pathway in fluid communication with the internal chamber, and an outlet fluid pathway in fluid communication with the internal chamber. The inlet fluid pathway extending into the chamber at a tangent to the curved interior wall, and the outlet fluid pathway spaced from the inlet fluid pathway such that fluid flowing into the internal chamber via the inlet fluid pathway is directed away from the outlet fluid pathway. The internal chamber is configured to create an internal fluid vortex in an injection fluid entering the internal chamber from the inlet fluid pathway, and wherein the internal fluid vortex at least temporarily suspends one or more air bubbles in the fluid in the internal vortex and delays the passage of the one or more air bubbles to the outlet fluid pathway.
