Device For Radiation Therapy Of Rectal Cancer
US Patent:
5685876, Nov 11, 1997
Filed:
Sep 18, 1995
Appl. No.:
8/529332
Inventors:
Frederic A. Gibbs - Salt Lake City UT
Christopher F. Johnson - Bountiful UT
Christopher F. Johnson - Bountiful UT
Assignee:
University of Utah Research Foundation - Salt Lake City UT
International Classification:
A61B 1700
US Classification:
606 1
Abstract:
A device for pushing a scar in the perineal region of a patient so that the scar can be optimally positioned during radiation treatment of the rectal area of the patient. A base is positioned beneath a patient's legs as the patient lies on a radiation therapy support platform. A guide and support member extends upwardly from the base so that the guide and support member is positioned between the thighs of the patient. A slide member is supported by the guide and support member, with the slide member being constrained to slide back and forth along the guide and support member in a direction substantially parallel to the patient's legs so that pressure can be exerted on the patient's perineum by the leading end of the slide member. The slide member can be moved manually, and a retaining mechanism is provided for releasably locking the slide member in any selected position along its movement. The device is used by manually moving the slide member toward the patient's perineum so that the leading end of the slide member pushes the perineal scar cephalad and then holds the scar in proper position during subsequent radiation therapy of the rectal area of the patient.
Device And Method For Precision Macular X-Irradiation
US Patent:
6134294, Oct 17, 2000
Filed:
Feb 13, 1998
Appl. No.:
9/023827
Inventors:
Frederic A Gibbs - Salt Lake City UT
Assignee:
University of Utah Research Foundation - Salt Lake City UT
International Classification:
A61N 510
US Classification:
378 65
Abstract:
A device for precision X-irradiation of the macular region of the retina of a patient's eye has a mounting plate mounted to a linear accelerator collimator. A housing extends from the mounting plate, and a secondary collimator is positioned in the housing. An elongate aperture extends through the secondary collimator and is in linear alignment with an axis of an X-ray beam emanating from the linear accelerator collimator. A support member extends outwardly from a side of the housing, and an elongate, hollow, sight tube is mounted on the support member. The longitudinal axis of the sight tube aligns with the axis of the X-ray beam so that the axis of the sight tube and the axis of the X-ray beam intersect each other. A light beam is transmitted down the sight tube. The light beam impinges on a cornea of a patient's eye.
