Modern Medical Science

The practice of medicine is based on diagnosis and treatment. A hundred years ago, the physician felt the pulse and came to various conclusions about illness. He had only few instruments to diagnose a disease. Within the last hundred years, medical technology developed. This carries information about development of medical science.

New methods of viewing diseased structures inside the body improved diagnosis of disease beginning in 1970 s.

• A Gamma Camera detects radioactive medication that attaches certain forms of cancer cells.

• Computed tomography (CT) scanners use X- Rays to produce life like three dimensional images of body structures

• Magnetic Resonance Imaging (MRI) scanners produce highly detailed images without X- Rays.

• X -Ray machine was invented by Wilhelm Rontgen in 1895.

• Positron Emission Tomography (PET) detects very early warning signs of disease.

• The CAT scan machine was invented in 1973.

• ECG machine was invented in 1975.

• The Danish physician Niels Ryberg Finsen developed an ultraviolet ray lamp.
