Patent number: 6022325Abstract: A motorized biopsy needle positioner employed in a mammographic needle biopsy system receives coordinate information representative of an identified point of interest within a patient's captive breast under examination and automatically positions a biopsy needle in accordance with that coordinate information to permit insertion of the biopsy needle to the identified point of interest. An offset mode of operation of the motorized biopsy needle positioner automatically positions the biopsy needle in accordance with coordinate information representative of an offset point within the patient's breast that is offset from the previously identified point of interest to permit insertion of the biopsy needle to that offset point. A manual mode of operation of the motorized biopsy needle positioner permits the user to actuate directional keys of a user control unit to position the biopsy needle in one or more directions, as specified by the actuated directional keys.Type: GrantFiled: September 4, 1998Date of Patent: February 8, 2000Assignee: Fischer Imaging CorporationInventors: Bernard Siczek, Menachem Assa, Michael A.

Patent number: 5569266Abstract: The disclosed system (10) employs an MRI device to identify the location of an area of interest within a patient's breast (28) and guide a medical instrument (26) for insertion to the identified location. The patient (30) is positioned on a table top (18) having an opening (52) through which the patient's breast (28) pendulantly projects. The pendulant breast (28) is immobilized by a basket (36). The table top (18) and patient (30) are then introduced into magnetic field generator (12) and MRI signals are received by receiver (14). The location of an area of interest within the patient's breast (28) is determined based on the received signals. A guidance assembly (24) can then be used to aim the medical instrument (26) towards the location of interest via a penetration path selected so as to avoid the receiver (14) and basket (36).Type: GrantFiled: September 13, 1993Date of Patent: October 29, 1996Assignee: Fischer Imaging CorporationInventor: Bernard Siczek

Patent number: 5526394Abstract: An apparatus is disclosed for imaging a patient's breast (18) by scanning an imaging signal (58) and a receiver (30) across the patient's breast (18) and then constructing a time-delay integration composite image based on the scan. The receiver (30) includes an array of radiation sensitive detector elements (132). Read out of the array (132) is synchronized with the scanning motion of the receiver (30) based on output from position encoder (104) such that synchronization is maintained despite scan drive variances. A novel assembly (106) is also disclosed for allowing selection of an appropriate radiation filter based on particular imaging conditions.Type: GrantFiled: November 26, 1993Date of Patent: June 11, 1996Assignee: Fischer Imaging CorporationInventors: Bernard Siczek, Emre Toker

Patent number: 3944141Abstract: Apparatus is disclosed for forming a paint spray gun having a protective hood about the spray orifice, wherein the hood may be pivotally lifted for cleaning and other purposes. A cam surface connected to the hood disables the spray gun trigger apparatus, which in turn prevents the spray gun paint valve from being actuated.Type: GrantFiled: May 19, 1975Date of Patent: March 16, 1976Assignee: Graco Inc.Inventor: Bernard Siczek
