Abstract
A system includes a probe configured to transmit ultrasound signals directed to a target blood vessel and receive echo information associated with the transmitted ultrasound signals. The system also includes at least one processing device configured to process the received echo information and generating a three-dimensional ultrasound image of the target blood vessel; obtain a three-dimensional vascular model corresponding to the target blood vessel; identify a best-fit of the three-dimensional vascular model onto the three-dimensional target image; store the best fit of the three-dimensional vascular model as a segmentation result; and calculate, based on the segmentation result, measurements for the target blood vessel.
Claims20
A system, comprising:
- a probe configured to:
- transmit ultrasound signals directed to a target blood vessel, and
- receive echo information associated with the transmitted ultrasound signals;
- and
- at least one processing device configured to:
- process the received echo information and generate a three-dimensional ultrasound image of the target blood vessel,
- obtain a flexible three-dimensional vascular model corresponding to the target blood vessel, wherein the flexible three-dimensional vascular model includes a statistical shape model derived from human samples and without using any mesh, and wherein the statistical shape model infers one of a statistical distribution;
- perform a shape fitting procedure of the flexible three-dimensional vascular model onto the three-dimensional ultrasound image of the target blood vessel, wherein the shape fitting procedure overlays the flexible three-dimensional vascular model onto the ultrasound image of the target blood vessel and morphs the flexible three-dimensional vascular model to match the ultrasound image of the target blood vessel,
- store a segmentation result based on the shape fitting procedure, and
- calculate, based on the segmentation result, measurements for the target blood vessel.
