Abstract
A method includes predicting a contrast bolus arrival time, and performing at least one of the following: a) automatically switching from a monitor phase to a scan phase at the predicted arrival time; and b) prompting a user to began a scan at the predicted arrival time.
Claims12
A method comprising:
- injecting a subject with a contrast bolus;
- predicting a contrast bolus arrival time at a region of interest, said predicting comprising monitoring a slope change of a time intensity curve and monitoring a derivative of the slope for consecutive declines in value;
- and
- performing at least one of the following:
- a) automatically switching from a monitor phase to a scan phase at the predicted arrival time;
- and
- b) prompting the user to begin a scan at the predicted arrival time.
4 more elements
A computer readable medium embedded with a program configured to instruct a computer to:
- receive data related to a contrast bolus injected into a patient;
- and
- predict a bolus transit time to a region of interest based on the received data by monitoring a slope change of a time intensity curve and a derivative of the slope for consecutive declines in value.
A system comprising:
- an x-ray source;
- an x-ray detector positioned to receive x-rays emitted from said source;
- and
- a computer operationally coupled to said source and said detector, said computer configured to:
- predict a contrast bolus arrival time at a region of interest by monitoring a slope change of a time intensity curve and a derivative of the slope for consecutive declines in value;
- and
- perform at least one of the following:
- a) automatically switch from a monitor phase to a scan phase at the predicted arrival time;
- and
- b) prompt a user to began a scan at the predicted arrival time.
