Abstract

An ultrasound imaging system and method includes acquiring ultrasound image data of an object while translating the ultrasound probe, where the ultrasound probe includes a scanning surface. The ultrasound imaging system and method includes displaying an acquisition view during the process of acquiring the panoramic ultrasound data. The ultrasound imaging system and method includes automatically determining acoustic contact of the scanning surface with the object while acquiring the panoramic ultrasound data and displaying a color-coded indicator at the same time as the acquisition view, where the color-coded indicator represents the acoustic contact of the scanning surface in real-time during the process of acquiring the panoramic ultrasound data.

First claim

What is claimed is:

1. A method of ultrasound imaging, said method comprising:
acquiring panoramic ultrasound data of an object while translating an ultrasound probe, wherein the ultrasound probe includes a scanning surface;
displaying an acquisition view during the process of acquiring the panoramic ultrasound data, wherein the acquisition view comprises a live image representing real-time ultrasound data acquired from a current position of the ultrasound probe and one or more still images displayed to the left of the live image, the one or more still images representing previously acquired panoramic ultrasound data, wherein a position of the live image is moved to the right with respect to the acquisition view during the process of acquiring the panoramic ultrasound data;
automatically determining acoustic contact of the scanning surface with the object while acquiring the panoramic ultrasound data;
displaying a color-coded indicator at the same time as the acquisition view, wherein the color-coded indicator represents the acoustic contact of the scanning surface in real-time during the process of acquiring the panoramic ultrasound data and comprises a bar extending an entire width of the live image and directly contacting a bottom edge of the live image, wherein the bottom edge is at an opposite side of the live image with respect to the ultrasound probe,
wherein the color-coded indicator is horizontally aligned with the live image during the process of acquiring the panoramic ultrasound data, and wherein the color-coded indicator is moved to the right during the process of acquiring the panoramic ultrasound data so that the color-coded indicator remains horizontally aligned with the live image as the live image is moved during the process of acquiring the panoramic ultrasound data;
wherein a length of the bar is color-coded such that the bar is displayed in a first color to indicate acoustic contact of the scanning surface in response to determining that the entire scanning surface has acoustic contact, the bar is displayed in a second color that is different from the first color to indicate that the scanning surface does not have acoustic contact in response to determining that entire scanning surface does not have acoustic contact, and a first portion of the bar is displayed in the first color to indicate acoustic contact for a corresponding first portion of the scanning surface and a second portion of the bar is displayed in the second color to indicate that a corresponding second portion of the scanning surface does not have acoustic contact in response to determining the first portion of the scanning surface has acoustic contact and the second portion of the scanning surface does not have acoustic contact.

2. The method of claim 1 , wherein said determining the acoustic contact of the scanning surface comprises comparing intensities of the panoramic ultrasound data to a threshold.

3. The method of claim 1 , wherein the first color is green and the second color is red.

4. The method of claim 1 , further comprising: identifying a first subset of the panoramic ultrasound data that was acquired with acoustic contact and a second subset of the panoramic ultrasound data that was acquired without acoustic contact; and generating a panoramic view comprising a plurality of videos based on the first subset of the panoramic ultrasound data, wherein the panoramic view does not include the second subset of the panoramic ultrasound data.

5. The method of claim 2 , wherein the threshold is determined based on the panoramic ultrasound data.

6. The method of claim 2 , wherein the threshold is determined based on a pre-scan ultrasound data of the object.

7. The method of claim 4 , wherein the panoramic ultrasound data was acquired from a lung and includes a plurality of intercostal spaces, and wherein the plurality of intercostal spaces are represented by the plurality of videos.

8. The method of claim 7 , wherein the panoramic ultrasound data includes a plurality of frames of ultrasound data, and wherein a first portion of one of the frames is in is in the first subset and a second portion of the frame is in the second subset.

9. The method of claim 7 , wherein the panoramic ultrasound data includes a plurality of frames of ultrasound data, and wherein the plurality of videos in the panoramic view are generated based on one or more of the plurality of frames of ultrasound data, portions of one or more of the plurality of frames with acoustic contact, or both one or more of the plurality of frames of ultrasound data and portions of one or more of the plurality of frames of ultrasound data with acoustic contact.

10. An ultrasound imaging system comprising:
a display device;
an ultrasound probe including a scanning surface;
and a processor in electronic communication with the ultrasound probe and the display device, wherein the processor is configured to:
control the ultrasound probe to acquire panoramic ultrasound data of an object while the ultrasound probe is translated;
display an acquisition view on the display device while the ultrasound probe is acquiring the panoramic ultrasound data, wherein the acquisition view comprises a live image representing real-time ultrasound data acquired from a current position of the ultrasound probe and one or more still images displayed to the left of the live image, the one or more still images representing previously acquired panoramic ultrasound data, wherein a position of the live image is moved to the right with respect to the acquisition view during the process of acquiring the panoramic ultrasound data;
display a color-coded indicator at a same time as the acquisition view, wherein the color-coded indicator represents an acoustic contact of the scanning surface in real-time while acquiring the panoramic ultrasound data and comprises a bar extending an entire width of the live image and directly contacting a bottom edge of the live image, wherein a length of the bar is color-coded, wherein the bottom edge is at an opposite side of the live image with respect to the ultrasound probe, wherein the color-coded indicator is horizontally aligned with the live image during the process of acquiring the panoramic ultrasound data, and wherein the color-coded indicator is moved to the right during the process of acquiring the panoramic ultrasound data so that the color-coded indicator remains horizontally aligned on the live image as the live image is moved during the process of acquiring the panoramic ultrasound data;
and display the bar in a first color to indicate acoustic contact of the scanning surface in response to determining that the entire scanning surface has acoustic contact; display the bar in a second color that is different than the first color to indicate that the scanning surface does not have acoustic contact in response to determining that the entire scanning surface does not have acoustic contact; and display a first portion of the bar in the first color to indicate acoustic contact for a corresponding first portion of the scanning surface and display a second portion of the bar in the second color to indicate that a corresponding second portion of the scanning surface does not have acoustic contact in response to determining the first portion of the scanning surface has acoustic contact and the second portion of the scanning surface does not have acoustic contact.

11. The ultrasound imaging system of claim 10 , wherein the processor is configured to adjust the color-coded indicator in real-time as the acoustic contact of the scanning surface changes.

12. The ultrasound imaging system of claim 10 , wherein the processor is further config
