Abstract
A strain imaging system may acquire first ultrasound data of a region of interest of a heart of a subject at a first frame rate during a first cardiac cycle of the heart of the subject. The strain imaging system may acquire second ultrasound data of a subset of the region of interest of the heart of the subject at a second frame rate during a second cardiac cycle of the heart of the subject. The strain imaging system may determine information related to cardiac deformation of the region of interest of the heart of the subject using strain imaging, the first ultrasound data, and the second ultrasound data. The strain imaging system may display the information related to cardiac deformation of the region of interest of the heart of the subject.
Claims20
A system comprising:
- a memory configured to store instructions;
- and
- one or more processors configured to execute the instructions to:
- acquire first ultrasound data of a region of interest of a heart of a subject at a first frame rate during a first cardiac cycle of the heart of the subject;
- segment the region of interest of the heart into a set of myocardial segments;
- track the set of myocardial segments during the first cardiac cycle;
- determine motion characteristics of the set of myocardial segments;
- determine the subset of the region of interest for which to acquire the second ultrasound data based on the motion characteristics;
