US Patent:

20130113791, May 9, 2013

Filed:

Dec 20, 2012

Appl. No.:

13/722259

Inventors:

Samuel Morris Johnston - Durham NC, US

Assignee:

MINISPINE, INC. - Lake Worth FL

International Classification:

G06T 11/60
G06T 3/00
G06T 15/00

US Classification:

345419, 345634, 345682, 345589

Abstract:

A system and method for displaying images of internal anatomy includes an image processing device configured to provide high resolution images of the surgical field from low resolution scans during the procedure. The image processing device digitally manipulates a previously-obtained high resolution baseline image to produce many representative images based on permutations of movement of the baseline image. During the procedure a representative image is selected having an acceptable degree of correlation to the new low resolution image. The selected representative image and the new image are merged to provide a higher resolution image of the surgical field. The image processing device is also configured to provide interactive movement of the displayed image based on movement of the imaging device, and to permit placement of annotations on the displayed image to facilitate communication between the radiology technician and the surgeon.

International Classification:

A61B 34/20
A61B 6/00
A61B 6/12
A61B 90/00

Abstract:

A computer-assisted imaging and localization system assists the physician in positioning implants and instruments into a patient's body. The system displays overlapping images—one image of the surgical site with the patient's anatomy and another image showing the implant(s) or instrument(s). The overlapping image of the implant/instrument is moved over the static image of the anatomy as the implant/instrument is moved. These moving image of the implant/instrument can be an unaltered image or an image altered to intensify or mitigate the anatomical or non-anatomical aspects of the moving image. Sliding these images over one another helps the surgeon in positioning devices or instruments with a high degree of accuracy and with a limited number of additional x-rays.
