Abstract
A method for bolus tracking includes acquiring one or more baseline images. One or more trigger regions are automatically established within the baseline images. A bolus is administered. The automatically established trigger regions are monitored for bolus arrival at the one or more trigger regions. Bolus arrival at a volume of interest is forecasted based on the bolus arrival at the one or more trigger regions. A diagnostic scan of the volume of interest is acquired at the forecasted time.
Claims26
A method for bolus tracking, comprising:
- acquiring one or more baseline images;
- automatically establishing one or more trigger regions within each of the one or more baseline images;
- administering a bolus;
- monitoring the automatically established trigger regions for bolus arrival at the one or more trigger regions;
- forecasting bolus arrival at a volume of interest based on the bolus arrival at the one or more trigger regions;
- and
- acquiring a diagnostic scan of the volume of interest at the forecasted time.
A method for bolus tracking, comprising:
- acquiring a scout image;
- automatically detecting a monitoring line within the scout image;
- acquiring a baseline image at a location determined by the location of the automatically detected monitoring line within the scout image;
- acquiring a baseline image;
- automatically establishing a plurality of trigger regions within the baseline image;
- administering a bolus;
- monitoring the automatically established trigger regions for bolus arrival at the one or more trigger regions;
- forecasting bolus arrival at a volume of interest based on the bolus arrival at the one or more trigger regions;
- and
- acquiring a diagnostic scan of the volume of interest at the forecasted time.
A computer system comprising:
- a processor;
- and
- a non-transitory, tangible, program storage medium, readable by the computer system, embodying a program of instructions executable by the processor to perform method steps for bolus tracking, the method comprising:
- acquiring a scout image;
- automatically detecting a monitoring line within the scout image;
- acquiring a baseline image at a location determined by the location of the automatically detected monitoring line within the scout image;
- acquiring a baseline image;
- automatically establishing one or more trigger regions within the baseline image;
- administering a bolus;
- monitoring the automatically established trigger regions for bolus arrival at the one or more trigger regions;
- forecasting bolus arrival at a volume of interest based on the bolus arrival at the one or more trigger regions;
- and
- acquiring a diagnostic scan of the volume of interest at the forecasted time.
