PPT on computers in medical field

3. Revealing key points
one at a time :-
Computers have become mainstream appliances, they have found their way into virtually all aspects of
human endeavors and medicine is no exception. Computers help physicians and medical researchers
discover, test and apply medical techniques in virtually every hospital in the world.
Furthermore, computer technology provides an infrastructure to allow for medical ideas and knowledge to
be filed and shared globally with other medical professionals.
Computers especially used in medical field are creating endeavors and thus, saving thousands of lives. It is
that part of human acknowledgement that has proved to be very beneficial, reaching every part of human
body left out or which was difficult to get into.

SCAN
A computerized tomography
(CT) scan combines a
series of X-ray images
taken from different angles
and uses computer
processing to create cross-
sectional images, or slices,
of the bones, blood vessels
and soft tissues inside your
body. CT scan images
provide more detailed
information than plain X-
rays do.
A CT scan has many uses,
but is particularly well-suited
to quickly examine people

RATE
MONITORING
A heart rate monitor is a device you wear
that measures and displays your heart
rate. It detects each heart beat and counts
it and displays the number of beats per
minute. Personal heart rate monitors are
used to measure exercise intensity.
Also Known As: HRM, Polar monitor,
cardio monitor
Heart rate monitors can continuously track
and record heart rate during exercise,
compared with an on-demand pulse
monitor which only shows a value at a
single point.
Many heart rate monitors save and
display the workout heart rate on a
graph compared to time, speed,
elevation and other aspects measured
during the workout. The time in different

SURGERY
Surgery is a medical specialty that uses
operative manual and instrumental
techniques on a patient to investigate or treat
a pathological condition such as a disease or
injury, to help improve bodily function or
appearance or to repair unwanted ruptured
areas.
The act of performing surgery may be called a
"surgical procedure", "operation", or simply
"surgery". In this context, the verb "operate"
means to perform surgery. The adjective
"surgical" means pertaining to surgery;
e.g. surgical instruments or surgical nurse.
The patient or subject on which the surgery is
performed can be a person or an animal.
A surgeon is a person who practices surgery

RESEARCH
Biomedical research (or experimental medicine)
encompasses a wide array of research from "basic
research involving the explanation of more
fundamental scientific principles, to clinical research,
which is distinguished by the involvement of patients.
Within this spectrum is applied research,
or translational research conducted to aid and support
the development of knowledge in the field of medicine,
and pre-clinical research, for example involving
animals.
Both clinical and pre-clinical research phases exist in
the pharmaceutical industry's drug development
pipelines, where the clinical phase is denoted by the
term clinical trial. However, only part of the clinical or
pre-clinical research is oriented towards a specific
pharmaceutical purpose. The need for fundamental and
mechanistic understanding, diagnostics, medical
devices and non-pharmaceutical therapies means that

Magnetic Resonance Imaging
(MRI) A magnetic resonance imaging instrument (MRI scanner), or
"nuclear magnetic resonance (NMR) imaging" scanner as it
was originally known, uses powerful magnets to polarize and
excite hydrogen nuclei (i.e., single protons) of water
molecules in human tissue, producing a detectable signal
which is spatially encoded, resulting in images of the body.
The MRI machine emits a radio frequency (RF) pulse at the
resonant frequency of the hydrogen atoms on water
molecules. Radio frequency antennas ("RF coils") send the
pulse to the area of the body to be examined. The RF pulse is
absorbed by protons, causing their direction with respect to
the primary magnetic field to change. When the RF pulse is
turned off, the protons "relax" back to alignment with the
primary magnet and emit radio-waves in the process. This
radio-frequency emission from the hydrogen-atoms on water
is what is detected and reconstructed into an image.
The resonant frequency of a spinning magnetic dipole (of
