Abstract
By example, a method includes: receiving ultrasound image data of a patient, including a segmented region corresponding to a liver; automatically identifying an area for a region of interest within the segmented region, wherein the region of interest corresponds to a region in the liver for performing shear-wave elastography; and presenting, on a display, the ultrasound image data and the area for the region of interest.
Claims13
A method comprising:
- receiving ultrasound image data of a patient, including a segmented region corresponding to a liver;
- prior to performing shear-wave elastography, automatically identifying an area for a region of interest within the segmented region using at least one mask, wherein the region of interest corresponds to a region in the liver for subsequently performing shear-wave elastography;
- and
- presenting, on a display, the ultrasound image data and the area for the region of interest,
- wherein said automatically identifying the area for the region of interest within the segmented region using the at least one mask further comprises:
- determining a first mask by filtering pixels that do not correspond to liver tissue;
- determining a second mask for identifying an axial position in the segmented region;
- determining a third mask for identifying a lateral position in the segmented region;
- combining the first mask, the second mask, and the third mask to limit the area for the region of interest within the segmented region;
- determining a fourth mask corresponding to image data in a region resulting from poor probe contact with the patient;
- and
- combining the first mask, the second mask, the third mask, and the fourth mask to limit the area for the region of interest within the segmented region.

An ultrasound imaging system comprising:
- a probe including at least one transducer configured to transmit ultrasonic waves and receive reflected ultrasonic waves;
- a display configured to present a presentation to an operator;
- and
- a processor configured to process data corresponding to the reflected ultrasonic waves to determine a segmented region corresponding to a liver of a patient, and further configured to cause the display to present the presentation,
- wherein the presentation includes image data of the segmented region and at least one dynamic region-of-interest indicator indicating a corresponding region of interest in the liver for subsequently performing shear-wave elastography, wherein the processor is configured to automatically determine the region of interest within the segmented region using at least one mask prior to performing shear-wave elastography,
- wherein the processor is further configured to automatically determine the region of interest from the segmented region using the at least one mask by:
- determining a first mask by filtering pixels that do not correspond to liver tissue;
- determining a second mask for identifying an axial position in the segmented region;
- determining a third mask for identifying a lateral position in the segmented region;
- combining the first mask, the second mask, and the third mask to limit an area for the region of interest within the segmented region;
- determining a fourth mask corresponding to image data in a region resulting from poor probe contact with the patient;
- and
- combining the first mask, the second mask, the third mask, and the fourth mask to limit the area for the region of interest within the segmented region.
