Abstract

An ultrasound imaging system includes an a processor circuit that stores, in a memory in communication with the processor circuit, a target parameter representative of a target anatomical scan window. The processor circuit receives a first ultrasound image acquired by a first ultrasound probe with a first anatomical scan window during a first acquisition period. The processor circuit determines a first parameter representative of the first anatomical scan window. The processor circuit retrieves the target parameter from the memory. The processor circuit compares the target parameter and the first parameter. The processor circuit outputs a visual representation of the comparison to a display in communication with the processor circuit.

First claim

What is claimed is:

1. A method of determining an anatomical scan window associated with an ultrasound image, comprising the steps of:
acquiring with an ultrasound probe a first ultrasound image with a first anatomical scan window during a first acquisition period;
analyzing the acquired first ultrasound image to determine the first anatomical scan window;
comparing a desired value of the scan window with the anatomical scan window from the analyzing step to determine whether the first anatomical scan window and the desired value of the scan window are the same or differ;
if the first anatomical scan window and the desired value of the scan window differ revert to and repeat the acquiring, analyzing, and comparing steps; and
if the first anatomical scan window and the desired value of the scan window are the same,
annotate the first ultrasound image with the determined scan window;
store the determined scan window and the first ultrasound image in a computer memory for subsequent use, and
retrieve the stored determined scan window and the first ultrasound image for use in a subsequent comparing step.

2. The method of claim 1 , further comprising the step of displaying the first ultrasound image along with the determined scan window.
