A Review of Portable Apparatus

Abstract

In this year, 1928, the radiological apparatus available for installation in modern departments has reached a high degree of efficiency; the gradual introduction and improvements in the design of the closed-iron transformer and its adoption in association with the hot cathode tube has placed at the disposal of the radiologist the means of obtaining a standardisation of results quite outside his reach some few years ago; it is perhaps with gratitude to those whose work we are indebted for our apparatus, and to our manufacturers for the progress which has been made, that we view our modern departments. Efforts are being made to standardise the apparatus to such an extent that the radiologist can devote himself to the diagnosis of the radiograms without having to concern himself with exact electrical data; this one feels is a step in the right direction. At the present day it would appear that demand is being made for extremely high milliamperage outfits, and the apparatus is available which will deliver two or three hundred milliamperes at a penetration of well over a hundred kilovolts peak. These outputs are demanded, and in consequence, the design of x-ray apparatus has become one of no small difficulty, demanding exact physical knowledge. With such an elaborate plant in our own departments, it is perhaps natural that we should feel that the production of a satisfactory radiogram in a patient's house must naturally be a hazardous undertaking, and to be avoided by every possible means in our power.
