Carl J Brunnett: Computer tomography assisted stereotactic surgery system and method. Picker International, Fay Sharpe Beall Fagan Minnich & McKee, December 20, 1988: US04791934 (591 worldwide citation)

Diagnostic mapping data representing a series of planar slices through a patient are generated by a CT or other multi-plane scanner (A) and stored in an image memory (32). To free the CT or other scanner for other patients, the mapping data and patient are transferred to a second location. At the se ...

During surgery, a physician speaks commands that are received by a microphone (10). A speech processor (12) converts audio signals from the microphone into word signals. A command interpreter (14) compares each word signal with a list of previously authorized command words. When the word signal corr ...

A CT scanner (A) non-invasively examines a volumetric region of a subject and generates volumetric image data indicative thereof. An object memory (B) stores the data values corresponding to each voxel of the volume region. An affine transform algorithm (60) operates on the visible faces (24, 26, 28 ...

An exoskeleton material (12), such as a thermoplastic mesh, is heat softened. The heat softened material is stretched over and conformed to a soft tissue region of the patient, such as a patient's breast. The material is allowed or caused to set or harden and is affixed (14) to a patient support (10 ...

A surgical guide for use with an image guided surgery includes first and second surfaces. At least three signaling devices such as infrared emitters are disposed on the first surface, and a cylindrical mounting boss is disposed on the second surface. A guide aperture is perpendicular to the first an ...

A patient supported on a patient support (12) is moved into a bore (22) of a planning imaging device, such as a CT scanner (20). A three-dimensional diagnostic image in three-dimensional diagnostic image space is generated and stored in a memory (130). The patient is repositioned outside of the bore ...

Frederick C Mailey, Robert A Cecil: Hingedly supported integrated trackball and selection device. Picker International, Fay Sharpe Beall Fagan Minnich & McKee, August 17, 1993: US05237311 (176 worldwide citation)

A trackball (10) is rotatably mounted on rollers (12, 14). The rollers are connected with rotational encoders (16, 18) for producing a series of pulses. Up/down counters (20, 22) convert the pulses into an indication of translation along two axes. Downward, non-rotational pressure on the trackball c ...

Gene H Barnett, Christopher H Wood, Patrick A Dayton: Apparatus for anatomical tracking. Picker International, Timothy B Gurlin, John J Fry, Eugene E Clair, November 9, 1999: US05980535 (174 worldwide citation)

A position signaling is usable in connection with an image guided surgery system. A plurality of infrared emitters are mounted on a reference object. The reference object is in turn attached to the rocker arm of a head clamp. The head clamp includes a frame and a first head engaging pin secured to o ...

Dale A Messner, Patrick A Dayton: Tool calibrator. Picker International, Timothy B Gurin, John J Fry, Eugene E Clair, November 23, 1999: US05987960 (164 worldwide citation)

A tool calibrator includes two portions shaped to slidably engage and secure a tool in a desired position. The tool is secured by a series of staggered V shaped grooves on each of the two portions having a known geometrical relationship with a diameter of a tool head of the tool. The tool calibrator ...
