Electron microscope
We know that microscope which is used to see the structure of
cells. But if we want to see internal organs and bacteria we must need
electronic microscope. Electronic microscope was an essential tool in the
discovery of bacteria that causes diseases. Scientist, Francis crick and James
Watson to make one of the most important discoveries of the 20th
century – the structure of DNA, the material which makes up our genes.
MRI scanner
Today commonly we are using this term MRI scan but actually
this is called as nuclear magnetic resonance (NMR). In 1950 Felix Bloch discovered a
strong signal. At the time Felix Bloch stuck realize NMR could be used to
examine the inside of human bodies. This idea is used to help the today’s
development of medicine and it was great helpful to detect the all problems in
human body.

x rays because he was passing a high voltage through a vacuum tube when he
noticed it sent out visible rays. These rays would leave traces on a
photographic plate. Roentgen was excited and named that ray is X rays (unknown)
which is now we are using many other medical purpose.
Endoscope
Endoscope was a thinking of a medical student his name
Heinrich Lamm. In 1930 he got a idea of using glass fibers to examine the
inside of the human body. For long time medical field fitted a miniature camera
