Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 10:
11. The ultrasound imaging system of claim 10, wherein:
the one or more classifier algorithms comprise a classifier algorithm trained to determine that an interventional instrument is present by:
comparing the composite tissue frame with a second composite tissue frame;
generating a frame difference based on the comparison, the frame difference representing the non-cyclic temporal change;
detecting the tissue warping based on the frame difference;
determining, based on the detection of tissue warping:
the presence of the interventional instrument; and
a location of the interventional instrument;

the composite tissue frame and the second composite tissue frame comprise composite tissue frames that are at least one of:
consecutive frames in time;
separated by a predetermined amount of time; or
separated by a predetermined quantity of frames; and

selection of the composite tissue frame and the second composite tissue frame is determined:
automatically, by the ultrasound imaging system based on an image-capture setting; or
by a user input.
