A.1 Build-Up, Peg, and Retainer Kit Options

If you want to use build-up to simulate tissue, you can put plates of either "solid water" or acrylic (optional accessories) securely on one or both sides of the Model 35300A Detector. Build-up pegs and retainer rings for securing the acrylic plates to the 35300A Detector are also available as optional accessories (see Figure A-1). The build-up pegs (a set of eight) screw into threaded holes in the 35300A Detector, (four build-up pegs can be installed on each side of the 35300A Detector). The retainer rings are held in position with set screws that are turned with a hex wrench also included with the Model 90100 TRACKER

System.
