Abstract
Methods and systems are provided for automatically characterizing lesions in ultrasound images. In one example, a method includes automatically determining an A/B ratio of a region of interest (ROI) via an A/B ratio model that is trained to output the A/B ratio using a B-mode image of the ROI and an elastography image of the ROI as inputs, and displaying the A/B ratio on a display device.
Claims19
A method, comprising:
- receiving a request to determine an A/B ratio of a region of interest (ROI) of an elastography image displayed to a user on a display device, the elastography image including an underlying B-mode image displayed to the user on the display device and an elastography overlay displayed on the underlying B-mode image, the elastography overlay including elastography information of tissue imaged in the underlying B-mode image and measured by an ultrasound probe of an ultrasound system;
- in response to receiving the request, adjusting a gain of the elastography overlay of the elastography image to generate a processed elastography image that includes the underlying B-mode image and the adjusted-gain elastography overlay on the underlying B-mode image, the adjusted-gain elastography overlay having a different gain than the elastography overlay that is displayed to the user;
- entering the processed elastography image and a selected B-mode image of the ROI as inputs to an A/B ratio model that is trained to output the A/B ratio using the selected B-mode image of the ROI and the processed elastography image of the ROI as inputs, wherein the selected B-mode image is the underlying B-mode image or a different B-mode image that includes the ROI, and wherein the A/B ratio comprises a width and/or an area of the ROI in the elastography overlay relative to a width and/or an area of the ROI in the selected B-mode image;
- and
- displaying the A/B ratio on the display device.

A method for an ultrasound system, comprising:
- displaying an elastography image to a user on a display device, the elastography image including an underlying B-mode image and an overlay on the B-mode image, the overlay including elastography information of tissue imaged in the B-mode image and measured by an ultrasound probe of the ultrasound system, the overlay displayed at a first transparency;
- receiving a request to adjust a transparency of the overlay to a second transparency, and in response, adjusting the transparency of the overlay displayed on the display device to the second transparency;
- receiving a request to determine an A/B ratio of a region of interest (ROI) of the elastography image displayed to the user on the display device, wherein the A/B ratio is a ratio of a first area of the ROI in the elastography image to a second area of the ROI in the B-mode image;
- responsive to receiving the request, further adjusting the transparency of the overlay of the elastography image to a third transparency to generate a processed elastography image, wherein the processed elastography image includes the adjusted-transparency overlay with the third transparency on the underlying B-mode image, and wherein the third transparency is different than the first transparency;
- entering the processed elastography image and the underlying B-mode image as inputs to a model trained to output the A/B ratio based on the processed elastography image and the underlying B-mode image;
- and
- outputting the A/B ratio for display on a display device.
