Tracking For Detection Of TEE Probe In Fluoroscopy Medical Imaging

摘要

A probe pose is detected in fluoroscopy medical imaging. The pose of the probe through a sequence of fluoroscopic images is detected. The detection relies on an inference framework for visual tracking overtime. By applying visual tracking, the pose through the sequence is consistent or the pose at one time guides the detection of the probe at another time. Single frame drop-out of detection may be avoided. Verification using detection of the tip of the probe and/or weighting of possible detections by separate detection of markers on the probe may further improve the accuracy.

主权项

1. A method for detection of a probe in fluoroscopy medical imaging, the method comprising:
scanning, with a fluoroscopy system, a patient with the probe within the patient, the scanning providing a sequence of frames of data representing the patient and the probe over time; detecting a plurality of pose hypotheses for the probe from the frames of data; selecting one of the pose hypotheses for each frame of data with an inference framework using the pose hypotheses for others of the frames of data; and aligning coordinates of the fluoroscopy system with the probe based on the selected pose hypothesis.
