Abstract
Apparatus and methods are provided for locating a target in a living body. Three cameras are supported at an elevated location such as on a wall or from a ceiling. The cameras are supplied as an integrated unit with a computer and are factory calibrated to said computer. A patient examining table is provided with a single radiation device, the radiation which is detectable by the cameras. The table is moved both horizontally and vertically to establish X, Y and Z coordinates relative to the room in which the installation is made. A hand held ultrasound probe is positioned to detect a target in a body disposed on said table, and an ultrasound scan screen apparatus displays the relation of the probe to the target, and also provides information for moving the table to position the target at a predetermined location.
