Abstract
A method and system for assisting a physician compute the 3D location of the tip of a surgical device inserted into a patient is described. A trained model computes the 3D location of the hidden portion of the surgical device based on live image data of the operative field. A display shows the tip of the surgical device and a 3D model of the body organ in a fused arrangement.
Claims20
A system for assisting a physician compute the 3D location of a tip of a surgical device inserted into an organ of a patient comprising:
- a plurality of cameras arranged outside of the patient to obtain operative-field image data;
- and
- a processor programmed and operable to compute the 3D location of the device tip based on the operative-field image data.
A method for assisting a physician perform a medical procedure on a patient with a medical device comprises locating a hidden portion of the medical device in an organ of the patient based on live camera images of the operative field.
The method as recited in claim 19, further comprising extracting at least one feature from the object, and computing a motion signature of the extracted feature based on tracking the extracted feature over time, and wherein the locating step is based on the motion signature.
