APPARATUS AND METHOD FOR DETECTING CANCER IN TISSUE Raymond V. damadian Patented February 5, 1974 #3,789,832 xcerpts from Raymond Damadian's patent application It has now been found that, by measuring the degree of organization of these selected molecules in cells being studied and comparing this with the degree of organization in a known cancerous cell, cancer cells can be detected. Furthermore, it has now been found that the less the organization the greater the malignancy therefore a scale can be made to provide a standard for basing a decision on the degree of malignancy Further apparatus is provided for scanning throughout the entire body during which time the relaxation times are measured for selected nuclei and compared with standards. In this way a determination can be made of the existence of cancer together with the location and degree of malignancy of the cancerous cells This patent describes a device that uses very powerful magnetic fields to resonate the nuclei in cells in a body. Collapsing the field and measuring the relaxation times gave a comparison to healthy cells Later advances in digital signal processing have resulted in magnetic resonance imaging(MRi)equipment with color-coded image viewing of living tissue and its chemical composition.
