System and method for remote radiology technician assistance

A method for saving bandwidth for transmission of a live video of a medical imaging procedure, comprising:

• receiving, at a first processor, an input transmitted over a low bandwidth communications channel from a second processor remotely located from the first processor, wherein the input comprises a size of a region of interest (ROI) of a video frame of the live video, a desired sub-sampling factor for the video frame, and a location of the ROI;
• transmitting, via a transmitter, over the low bandwidth communication channel from the first processor to the second processor the ROI from the video frame at a first resolution and a sub-sampled frame of the video frame at a second resolution, wherein the first resolution is greater than the second resolution, and the first resolution is the resolution at which the live video is captured;
• and
• receiving, at the second processor, the ROI from the video frame at the first resolution and the sub-sampled frame at the second resolution;
• and
• displaying, on a display coupled to the second processor, a composite video frame of the live video with the ROI at the first resolution and a region outside the ROI at the second resolution.

A system, comprising:

• a first processor;
• a camera coupled to the first processor, wherein the camera is configured to capture a live video of a medical imaging procedure;
• a transmitter coupled to the first processor, wherein the first processor, the camera, and the transmitter are located at a first location;
• a second processor;
• and
• a display coupled to the second processor, wherein the second processor and the display are located at a second location remote from the first location;
• wherein the first processor is configured to:
• receive an input transmitted over a low bandwidth communications channel from a second processor remotely located from the first processor, wherein the input comprises a size of a region of interest (ROI) of a video frame of the live video, a desired sub-sampling factor for the video frame, and a location of the ROI;
• and
• transmit, via the transmitter, over the low bandwidth communication channel to the second processor the ROI from the video frame at a first resolution and a sub-sampled frame of the video frame at a second resolution, wherein the first resolution is greater than the second resolution, and the first resolution is the resolution at which the live video is captured;
• and
• wherein the second processor is configured to:
• receive the ROI from the video frame at the first resolution and the sub-sampled frame at the second resolution;
• and
• display, on a display, a composite video frame of the live video with the ROI at the first resolution and a region outside the ROI at the second resolution.
