More Information
Summary:A system processes pixel representative image data of medical images of patient anatomy to automatically identify an interventional instrument. The system includes an acquisition processor that receives pixel luminance data comprising multiple sequential medical images of a patient anatomical portion and luminance data of an individual image comprises multiple pixel luminance representative values of multiple individual pixels of the individual image. An image data processor detects and subtracts background image data from the pixel luminance data comprising the multiple sequential medical images to provide processed pixel luminance data comprising multiple processed sequential medical images. The image data processor computes gradient components of individual pixels of the processed pixel luminance data. The image data processor modifies the computed gradient component data by suppressing computed gradient components lacking symmetry about an interventional instrument width dimension and filters the modified computed gradient component data for use in providing image representative data showing the interventional instrument.
