Abstract
While x-ray computed tomography (CT) is falling in price it is still beyond the means of most primary and secondary health care centres in the world. I would like to show how if a teleradiology system is installed there is a good prospect for also being able to install a simple but diagnostically effective CT system. This can be based on film used either as a one or two dimensional detector. 1. CT SYSTEMS The major components of a CT system are: 1) health care worker(s) who can decide which part of a patient needs to be imaged 2) an x-ray transparent bed on which a patient can be made comfortable positioned and restrained as necessary 3) an x-ray source mounted on a gantry 4) an x-ray detector mounted on the gantry 5) a digitizer for the x-ray signal 6) a computer to receive the signal 7) an algorithm that calculates the reconstructed CT image 8) a halftone or color display monitor 9) a radiologist who can interpret the images 10) communication from the radiologist to the health care worker(s). 2. BENEFITS OF CT VIA TELERADIOLOGY I would like to proceed on the premise that a teleradiology system could be placed between steps 6 and 7. This has the following benefits: a) Radiologists who are relatively scarce and generally located in urban tertiary care centres could serve people in remote areas
