Patent number: 5515416Abstract: This invention relates to a bi-plane X-ray imaging medical system having two radiation axis with a common isocenter for simultaneous viewing of a targeted object in two planes for three dimensional orientation, these two radiation axes can be rotated about the isocenter, thus rotating these two planes individually or simultaneously and varying the angle between them for most advantageous imaging. And further, varying the angle allows for larger opening for access to the patient during a surgery or for loading/unloading the patient.Type: GrantFiled: May 30, 1995Date of Patent: May 7, 1996Inventors: Bernard W.

Patent number: 5386447Abstract: An apparatus (10) for use in performing medical procedures on a breast of a patient is disclosed. The apparatus (10) includes a frame assembly (12) for supporting the patient having an opening (22) therein through which the patient's breasts are permitted to protrude, an imaging system (18) for identifying any suspicious lesions within the patient's breasts, and a biopsy assembly (20) for use in performing a biopsy on the patient's breasts. The frame assembly (12) is tiltable from a vertical position to a non-vertical position to facilitate mammography and the mammographic biopsy procedure. In addition, the imaging system (18) and biopsy assembly (20) are moveable across the patient's chest from one breast to the other. The imaging system (18) is also rotatable and tiltable relative to the patient's breasts to obtain oblique views of the breasts.Type: GrantFiled: September 23, 1992Date of Patent: January 31, 1995Assignee: Fischer Imaging CorporationInventor: Bernard W.

Patent number: 5086447Abstract: An overhead X-ray apparatus for imaging in the bi-plane configuration which apparatus has the radiation isocenter vertically displaceable. A C-arm (or a like) for supporting an X-ray tube and image receptor is mounted on a carriage assembly in a rotatable arrangement about a vertical axes. The carriage assembly comprises a support frame and a slideable support mounted on overhead rails coupled by a scissor mechanism. A distance between the support frame and the slideable support and, hence the vertical position of the radiation isocenter can be varied by action of chains or timing belts connecting the support frame with the anchoring member which moves along the slideable support while actuated by an actuator.Type: GrantFiled: June 4, 1990Date of Patent: February 4, 1992Inventors: Aldona A.
