Positioning function mammographic biopsy function system with offset
First Claim
1. A method for performing medical procedures on a patient'"'"'s breast, comprising the steps of:
- a) displaying a first image of said patient'"'"'s breast corresponding to a first viewpoint;
b) displaying a second image of said patient'"'"'s breast corresponding to a second viewpoint;
c) providing an input device for obtaining positional information regarding locations of interest within said patient'"'"'s breast, said input device including a visual cue which is positionable relative to said displayed images, wherein positional data relative to a position of said visual cue is obtained by activating said input device;
d) viewing said displayed images of said patient'"'"'s breast to identify and determine three-dimensional coordinates of a selected location of interest within said patient'"'"'s breast by positioning said visual cue relative to said selected location of interest as viewed in said first image of said patient'"'"'s breast and activating said input device to obtain first image data, positioning said visual cue relative to said selected location of interest as viewed in said second image of said patient'"'"'s breast and activating said input device to obtain second image data and employing said first image data and said second image data to determine said three-dimensional coordinates of said selected location of interest within said patient'"'"'s breast; and
e) viewing only one of said displayed images of said patient'"'"'s breast to identify and determine three-dimensional coordinates of at least one offset location which is spatially offset relative to said selected location of interest by positioning said visual cue relative to said offset location as viewed in said only one of said displayed images of said patient'"'"'s breast and activating said input device to obtain offset data.

Abstract
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.

4. An apparatus for performing medical procedures on a breast of a patient, comprising:
-
(a) support means for supporting a patient'"'"'s breast in an imaging position relative to a predetermined frame of reference; (b) transmitting means, disposed in predetermined relation to and positionable relative to said predetermined frame of reference, for transmitting an imaging signal through a patient'"'"'s breast; (c) receiving means, disposed in predetermined relation to and position able relative to said predetermined frame of reference, in opposing relation to said transmitting means with a patient'"'"'s breast positioned therebetween, for receiving at least a portion of said transmitted imaging beam passing through a patient'"'"'s breast and for providing imaging information regarding said received signal portion; (d) identifying means, employing said imaging information, for identifying locations of interest within a patient'"'"'s breast so as to permit determination of three dimensional coordinates of said identified locations of interest within said predetermined frame of reference, said identifying means including display means for displaying first and second images of a patient'"'"'s breast corresponding to first and second imaging viewpoints, respectively, relative to said predetermined frame of reference, and an input means for obtaining positional information regarding said locations of interest within a patient'"'"'s breast, said input means including a visual cue which is position able relative to said displayed images, wherein positional data relative to a position of said visual cue is obtained by activating said input means, said identifying means including first means for allowing a user to determine three-dimensional coordinates of a selected location of interest within a patient'"'"'s breast by first viewing said displayed images of a patient'"'"'s breast, positioning said visual cue relative to said selected location of interest as viewed in said first image of a patient'"'"'s breast and activating said input means to obtain first image data, secondly, viewing said displayed images of patient'"'"'s breast positioning said visual cue relative to said selected location of interest as viewed in said second image of a patient'"'"'s breast and activating said input means to obtain second image data and employing said first image data and said second image data to determine said three-dimensional coordinates of said selected location of interest within a patient'"'"'s breast; and said identifying means further including second means for allowing a user to determine three-dimensional coordinates of at least one offset location which is spatially offset relative to said selected location of interest by viewing only one of said displayed images of a patient'"'"'s breast, positioning said visual cue relative to said offset location as viewed in said only one of said displayed images of a patient'"'"'s breast and activating said input means to obtain offset data. - View Dependent Claims (5, 6, 7)
