Abstract: A system, method, and computer-readable medium are disclosed for extracting breathing pattern data from ultrasound images for aiding downstream clinical patient management, including detecting a trigger event indicative of a breathing pattern from at least one of an audio-based trigger and an image-based trigger from an ultrasound video stream. The presently disclosed technique may further include identifying a breathing pattern in the ultrasound video stream responsive to detection of the trigger event. The presently disclosed technique may also include extraction of at least one breathing-related parameter and the generation of a record with the at least one breathing-related parameter.

Abstract: A system (100) for medical imaging is described. The system (100) includes: a computer tomography (CT) device (502) having a table (106); a processor; and a memory (130) that stores instructions. When executed by the processor, the instructions cause the processor to: compile ground truth data from measured BFS at a plurality of locations of an examined portion of a body, including each of a plurality of specific locations (201); train a computational model (211) to predict BFS using the ground truth data; infer BFS's throughout the examined portion of the body based on the computational model (211); and determine a contrast medium injection duration, or a speed of a table (106), or both, prior to a CT scan (402) based on the inferred BFS's. A method (600) and a tangible non-transitory computer readable medium are also disclosed.
