摘要： A sensor including an eddy current loop and an ultrasonic transducer transmitting along a common axis is placed against a second surface of a graphite/epoxy composite structure whose first surface has been formed over the surface of a steel model. The eddy current coil can produce a signal measuring the separation between the sensor and the surface of the steel model, and the ultrasonic transduer can produce a signal representing the thickness of the graphite/epoxy composite panel. The distance and thickness signals are passed to electrical circuitry that computes their difference and displays the calibrated result as a measure of the gap between the steel model and the graphite/epoxy tool.

摘要： A light weight syringe shield for use with syringes containing radioactive materials. The shield includes an outer shell of lead or similar gamma ray impervious material and a correspondingly configured inner shell of synthetic resinous materials. Both shells are of arcuate cross section, and extend through an arc substantially greater than 180 degrees so as to be selectively spread to enable the shield to be snapped laterally on the barrel of the syringe to be resiliently retained thereby. The shield is sufficiently long to cover that part of the barrel normally filled with the radioactive material, and it may be slid longitudinally of the barrel to permit calibration in an ion well chamber, as well as when the syringe is in use.

摘要： A phantom simulation imaging quality control device that effectively simulates one centimeter lesions, using steel ball bearings as gamma ray attenuators. The bearings are mounted in a synthetic resinous sheet in an orthogonal pattern. The phantom can provide uniformity, resolution, linearity, distortion and field size checks, all with a single exposure.
