REPORTER: "This new technique is made possible because of the CAT Scanner. Put simply, it is an X-Ray machine tied to a computer. The CAT Scanner - as shown in this demonstration can X-Ray the body layer by layer, taking as little as an eighth of an inch at a time - although half-inch sections are more typical. The two men who developed this phenomenal machine won the Nobel Prize this year for its development. The CAT Scanner shows the body as it has never been seen before, and doctors have been finding smaller tumours they could not see before. But there was a problem. There was no way of finding and removing the small tumours - until now. The Huntington Institute, along with the Jet Propulsion Lab - part of NASA - both in Pasadena, have developed a way of pinpointing the smaller tumour - typically the size of an eraser on a pencil - and getting it out.
The technique, known as the Sheldon Stereotactic Procedure has been called the most significant event in neurosurgery in Twenty-five years. Small cancerous tumours can now be discovered and removed."
C. HUNTER SHELDEN: "A very precise method of localising tumours when they are small enough so that we think their removal will have so fe cells that conventional or other type of locally given therapeutic procedures may relieve or may cure the tumour.
REPORTER: "Surgeons can now find how far over, across and down the tumour is. When the CAT Scan is used, this ring is placed on the patient's head. The ring has pins on it, each is a different length. And by looking at the Cat-Scan - and the rings on the Cat-Scan - surgeons know how deep the tumour is. And by using that same ring in surgery, they can remove most of the tumour. Also very important here is the Shelden Tumourscope, which goes into the brain at that precise spot. It allows surgical instruments to go in - as well as a three-dimensional viewer. Cancerous tumours are almost always fatal, and even after this surgery, they can still grow back. the long-term effect of this technique is not known, but it is felt that a patient's chances will be greatly improved if a tumour can be removed when it is small, and other forms of therapy used to rid the body of cancer. It is felt that this is a major breakthrough and that there is much more to come."

Background: In the United States, a breakthrough in the field of brain surgery. It involves the matching of computer, X-Ray and diagnostic technology and comes in the form of the Computerised Axial Tomography Scanner - otherwise known as the CAT Scanner. From the Huntington Institute of Applied Medical Research in California, Paul Dandridge reports.
