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 ...

Carl J Brunnett: Method and apparatus for improved radiation detection in radiation scanning systems. Picker Corporation, Watts Hoffmann Fisher & Heinke Co, October 4, 1977: US04052620 (124 worldwide citation)

An improved radiation measuring and processing unit for a radiation scanning system precisely determines the average intensity of a beam of radiation as it impinges upon a radiation detector during a primary time period of predetermined duration. The unit computes the average intensity by detecting ...

Hugh T Morgan, Darrell M Smith, Carl J Brunnett: Separate and combined multi-modality diagnostic imaging system. Picker International, Fay Sharpe Fagan Minnich & McKee, March 20, 2001: US06205347 (108 worldwide citation)

A multi-modality diagnostic imaging system includes a first imaging subsystem (A), such as a computed tomographic (CT) system, for performing a first imaging procedure on a subject. A second imaging subsystem (B), such as a nuclear medicine system (NUC), performs a second imaging procedure on a subj ...

James E Burke, Lester Miller, Rodney A Mattson, Carl J Brunnett, Theodore A Resnick: Computerized tomographic scanner having a toroidal x-ray tube with a stationary annular anode and a rotating cathode assembly. Picker International, Fay Sharpe Beall Fagan Minnich & McKee, April 19, 1994: US05305363 (60 worldwide citation)

A toroidal x-ray tube (I) is supported (II) for rotation about a horizontal axis (170), translation along a vertical axis (172), and translation along a horizontal axis (174). The x-ray tube includes a toroidal housing (A), an annular anode (B), and a cathode (0) which rotates a beam of electrons ar ...

Carl J Brunnett, Chris J Vrettos: CT scanner having multiple detector widths. Picker International, Fay Sharpe Beall Fagan Minnich & McKee, November 24, 1992: US05166961 (34 worldwide citation)

A CT scanner (10) includes a radiation source (12) mounted for rotation about a scan circle (14). A ring of radiation detectors (30) includes narrow detectors (30.sub.n) and wide detectors (30.sub.w). The narrow and wide detectors are separately sampled (42.sub.n, 42.sub.w) and operated on with diff ...

Carl J Brunnett, Jerome R Cox Jr, Donald L Snyder, Rodney A Mattson: Transverse tomography system having multibeam orbital scanning with all beams offset from the center of orbit. Picker Corporation, Watts Hoffmann Fisher & Heinke, February 15, 1977: US04008400 (26 worldwide citation)

A dual axial scanner in a transverse tomography system collects nonredundant data throughout one or more substantially 360.degree. orbital scan paths with uniform motion about a patient. A set of N X-ray beams scans the patient in a manner to allow collection of two sets of non-redundant data corres ...

Carl J Brunnett, Rodney A Mattson: Radiation detector. Picker International, Watts Hoffmann Fisher & Heinke Co, September 26, 1989: US04870667 (22 worldwide citation)

An improved computed tomography radiation detector is disclosed. One embodiment includes first and second layers of crystalline scintilation material mutually aligned in a path of x-rays to be detected, to receive the x-rays in sequence. The layer upstream in the x-ray path comprises a scintillation ...
