First Claim
Patent Images
1. A method, comprising:
- determining, via a hardware processor, an end systolic imaging trigger;
prospectively gating a first scan performed using an imaging system, and gated based at least on the end systolic imaging trigger, wherein first cardiac imaging data is acquired with the prospective gating, by the imaging system during the first scan and the first imaging data corresponds to a first predetermined data acquisition interval surrounding end systole;
determining, via the hardware processor, an end diastolic imaging trigger;
prospectively gating a second scan performed using the imaging system, and gated based at least on the diastolic imaging trigger, wherein second cardiac imaging data is acquired with the prospective gating by the imaging system during the second scan and the second imaging data corresponds to a second predetermined data acquisition interval about end diastole; and
post-processing the first and the second cardiac imaging data.

5. A method, comprising:
-
determining, via a hardware processor, an end systolic imaging trigger; gating a first scan performed with an imaging system, via prospectively gating, based at least on the end systolic imaging trigger, wherein first cardiac imaging data is acquired by the imaging system during the first scan and the first imaging data corresponds to a first predetermined data acquisition interval surrounding end systole; determining, via the hardware processor, an end diastolic imaging trigger; gating a second scan performed with the imaging system, via prospectively gating, based at least on the diastolic imaging trigger, wherein second cardiac imaging data is acquired by the imaging system during the second scan and the second imaging data corresponds to a second predetermined data acquisition interval about end diastole; post-processing the first and the second cardiac imaging data based on the end systolic imaging trigger and the end diastolic imaging trigger; and simulating imaging data between the first and second imaging data based on an anatomical model of the heart and boundary conditions determined based on the end systolic imaging trigger and the end diastolic imaging trigger.
