Communication:X - Ray Vision —— The CAT Scan
X - ray machine is called the CAT scan. It wasn't until 1971 that there was a major breakthrough in X ray technology. A physicist invented a computer system X ray machine that could take a photograph along a X wide plain inside the brain. This photograph slices the brain which called a tomograph. And for his Comuterized Axial Tomographic Scanner, CAT scanner for short, the physicist was awarded Nobel Prize. How does the CAT scanner actually help us find the unknow number or density inside the boday? You may find the answer in this programme.
