THE X-RAY’S NEW EYE
In 1895, when the X-ray was discovered by Roentgen, it was a marvel of modern science. Now the X-ray has a brother – the EMI Scanner. This is a machine which can produce pictures of more kinds of body tissues in more detail than the ordinary X-ray can. It can show the difference, for example, between blood and water. The first EMI Scanner was designed to examine the brain. Now EMI also produces a more complicated Scanner which can examine slices of body tissue. It gives doctors more information about their patients and helps doctors make more accurate diagnoses.
The machine is very expensive for the average hospital. It has a bed where the patient lies down and above the bed there is a scanning unit which contains the X-ray tube and sensitive detectors. The computer, control panel and television screen are all in another room, where the operator of the Scanner sits and from where he can watch the patient.
The Scanner examines the body in slices, 13 mms thick. To make a picture of a complete slice takes only 20 seconds. An X-ray beam passes through the slice 18 times at a different angle each time. The way in which X-ray is absorbed by the tissues is read by the detectors. During the 20 seconds, there are 300,000 readings. The computer receives all this information, processes it and makes a picture of the slice, which is seen on the television screen. The information is then stored by the computer. It is very important that the scanning only takes 20 seconds. This means that the patient can stay still and the readings are not affected by the movement of the body or by the patients breathing.
The Scanner is still young. But EMI have research programmes in many countries. So far there are 600 Scanners being used in over 30 countries in Europe, America, Russia and Japan.
