Computer Vision Systems and Methods for Real-Time Localization of Needles in Ultrasound Images

A system for real-time localization of a medical device in a video, comprising:

• a processor;
• and
• a memory in communication with the processor, the memory having computer instructions stored thereon which, when executed, cause the processor to perform the following steps:
• receiving a plurality of frames from the video;
• identifying one of the plurality of frames as a background image and a frame adjacent to the background image as a current image;
• performing a bitwise complement operation on the background image to generate a complement image;
• and
• performing a pointwise logical AND operation on the complement image and the current image to identify the location of the medical device.

A non-transitory computer-readable medium having computer-readable instructions stored thereon which, when executed by a computer system, cause the computer system to perform the steps of:

• receiving at a processor a plurality of frames from a video;
• identifying by the processor one of the plurality of frames as a background image and a frame adjacent to the background image as a current image;
• performing by the processor a bitwise complement operation on the background image to generate a complement image;
• and
• performing by the processor a pointwise logical AND operation on the complement image and the current image to identify the location of a medical device.
