Edward Joseph Hoffman

Died 1 Jul 2004 at age 62 (born 1 Jan 1942).American biomedical physicist whohelped create(1974) the PET Scanner (Positron Emission Tomography), which is used to detect cancers and other diseases.Michael E Phelps and others sharecreditfor this invention. A patient is prepared for a PET scan with an injection of slightly radioactive material, typically tagging molecules that behave like glucose within the body. Since cancerous tissues consume glucose, the scanner can then detect their location. PET technology can also be employed in the diagnosis of cardiovascular disease and Alzheimer's disease. Hoffman further developed the PET Scanner for use in making quantitative measurements. He became internationally known in the field of medical imaging. By the time he died in 2004, some 1,500 scanners were in use as a powerful diagnostic tool for saving or extending lives.«
