Abstract
A system, method, and computer program product are disclosed for occlusion detection and/or pressure limiting in a fluid injector system. A fluid injector system may include at least one fluid injector device, one or more drive components, and a control device. The control device may comprise at least one processor programmed or configured to: provide instructions to the fluid injector system to deliver fluid from the at least one fluid injector device at a predetermined fluid flow rate, determine a first fluid pressure measurement within the at least one fluid injector device at a first time, determine a second fluid pressure measurement within the at least one fluid injector at a second time, determine a pressure differential between the first fluid pressure measurement and the second fluid pressure measurement, calculate a change in compliance volume of the at least one fluid injector device based on the determined pressure differential, compare the calculated change in compliance volume with the predetermined fluid flow rate, repeat the steps throughout the fluid injection procedure, and determine whether an occlusion or a partial occlusion has occurred downstream of the at least one fluid injector device.
