Abstract
Described herein is a method of registering a medical image of a subject with a 3D model of a subject, including calibrating the 3D model globally by aligning markers on the subject with corresponding markers on the 3D model; and calibrating the 3D model locally by aligning a scanning image of an internal structure of the subject with a corresponding internal structure of the 3D model. Also described herein is an apparatus of performing the method.
Claims20
A method of registering a medical image of a subject with a three-dimensional (3D) model, comprising:
- calibrating, by a processor, the 3D model globally by aligning markers on the subject with corresponding markers on the 3D model;
- and
- calibrating, by the processor, the 3D model locally by aligning a scanning image of an internal structure of the subject with a corresponding internal structure of the 3D model.
An apparatus of registering a medical image of a subject with a 3D model, comprising:
- a tracking system, comprising:
- a position sensor, wherein the position sensor is attachable to a probe;
- and
- a navigation transducer, wherein the navigation transducer is configured to detect a position and an orientation of the probe via the position sensor;
- a memory for storing a 3D model of the subject, wherein the 3D model includes an 3D model of an internal structure of the subject;
- and
- a processor connected to the tracking system, wherein the processor is configured to:
- calibrate the 3D model globally by aligning markers on the subject with corresponding markers on the 3D model;
- and
- calibrate the 3D model locally by aligning a scanning image of the internal structure of the subject with the internal structure of the 3D model.
