Patient Phantom/Penetrometer System

To check the tabletop output of image intensified fluoroscopic equipment properly, a simulated body or phantom should be placed between the x-ray output meter and the input phosphor. The phantom protects the phosphor from the direct beam and provides the simulated attenuation needed to check the performance of image-intensifier systems. A penetrometer permits the determination of system contrast gradient under simulated operating conditions.

The Model 07-706 consists of:

(a) Two 7 x 7 x 0.75 inch blocks of high-purity aluminum, which represent the equivalent absorption of 26 cm of water and simulate a thick or heavy-set patient at 90 kVp. A single block is the equivalent of a child or adult chest. Aluminum simulates the scatter characteristics of the human body.

(b) One 7 x 7 x0.125 inch lead beam-stop plate. When placed in the beam, this plate allows automatic brightness-control machines to deliver maximum output.

(c) One 7 x 7 x 0.03125 inch aluminum penetrometer plate with 0.25, 0.176, 0.125, 0.088, and 0.0625 inch holes. Place this plate between the two aluminum blocks and ascertain the contrast gradient of the penetrometer on image-amplified systems.

(d) Two sets of legs: one 1.25 inch long and one 10.375 inch long.
