11. REMOTE CONTROL FUCTION & OPERATION
11.1. INTRODUCTION
Currently, mAs, kVp and Pre-set memory techniques (Prom memory) can be selected by the operator
by depressing push buttons or by scrolling displays on a control panel. Each technique or mode
selection depends on an anatomic region or view for radiographic examination. The collimator lamp
and laser pointer is turned “on” by the lamp push-button and turned “off” by a 30 second collimator
timer run off.
Many portable operators and field users have suggested we find a better way to select an exposure
technique and parameters along with mAs, kVp and pre-set Prom memory values. Most field operators
hold portable X-Ray units with one hand, while holding the exposure hand switch with the other hand.
This makes selecting technique factors on the control panel awkward without dropping the portable
unit or hand switch. We have modified our X-ray portable software and functions of the Prep. and
Exposure hand switch to allow selection of all exposure parameters (mAs & kVp) and control of the
collimator lamp and laser beam.
The exposure hand switch consists of a two step hand switch. The first (1) stage of the hand switch is
called the “Preparation (Prep. or Ready)” stage. The second (2) stage of the hand switch is called the
“Exposure (Exp or X-Ray out)“ stage. (See drawing 1.)
All functions of the remote control described above are executed by clicking the first stage on the hand
switch which is the “Prep.” mode of operation. Each remote control function and technique value
selection is described below.
