Abstract
An apparatus and method is provided for coordinating two fluoroscope images, which permits accurate computer-based planning of the insertion point and angle of approach of a needle, drill, screw, nail, wire or other surgical instrumentation into the body of a patient, and subsequently guides the surgeon in performing the insertion in accordance with the plan.
Claims55
A computer-aided method for planning a surgical procedure comprising:
- registering to a known coordinate frame a first two-dimensional, image of a body's anatomy taken at a first observation angle;
- displaying the first image;
- and
- drawing in the displayed first image a representation of a surgical object to be placed in the body based on the registration of the first image with the known coordinate frame.
A computer readable storage medium encoded with instructions, which, when read by a computer, enable a computer to undertake a process comprising:
- registering to a known coordinate frame a first two-dimensional, image of a body's anatomy taken at a first observation angle;
- displaying the first image;
- and
- drawing in the displayed first image a representation of a surgical object to be placed in the body based on the registration of the first image with the known coordinate frame.
A computer-aided method for planning a surgical procedure comprising:
- registering a first two-dimensional, image of a body's anatomy taken at a first observation angle with a second two-dimensional image of the body's anatomy taken at a second observation angle;
- displaying the first image;
- drawing within the displayed first image drawing within the displayed first image a representation of a surgical object to be placed in the body based on an input indicating a position of the surgical object;
- displaying the second image;
- and
- drawing in the displayed second image the representation of the surgical object.
A computer readable storage medium encoded with instructions, which, when read by a computer, enable a computer to undertake a process comprising:
- receiving a first two-dimensional, image taken of a patient's body and a plurality of radio-opaque fiducials placed adjacent the body at known positions;
- and
- registering the image by optimizing parameters of a known geometric model such that projections of the plurality of fiducials into the first image best fit positions of the plurality of fiducials in the image.
