PROCESING THE RADIOGRAPH-DIGITAL IMAGE PROCESSING NOTES

LINK UPDATED

THIS IS THE BEST ARTICLE ON PROCESSING THE RADIOGRAPH AS FAR AS DIGITAL IMAGE PROCESSING IS CONCERNED

SUMMARY HAS BEEN GIVEN BELOW

FULL ARTICLE CAN BE DOWNLOADED FROM THIS LINK GIVEN BELOW IT IS REALLY INFORMATIVE AND EASY TO LEARN

IT IS A SURE SHOT QUESTION OF MDU ROHTAKL ALSO.

SUMMARY

When an X-ray film has been exposed, it must be processed in order to produce a

permanent visible radiographic image that can be kept without deterioration for a number of

years. Processing transforms the latent image into a visible image. The term for the

several procedures that collectively produce the visible, permanent image is processing

and consists of developing, rinsing, fixing, washing and drying procedures

DIFFERENT ROLES OF A BIOMEDICAL ENGINEER IN JOBS

Biomedical engineers are an important part of the medical community. The knowledge, inventions, and people that are behind many biomedical engineering jobs are responsible for improving lives across the globe by creating new theories on life systems or designing medical instruments.

The contributions made by those employed in biomedical engineering jobs are countless: minuscule devices to inhibit cell growth; artificial bones, tendons, and discs; highly sensitive monitors and medical imaging systems; artificial hearts; synthetic blood; medical robotics; and tissue engineering – to name just a few.

Acoustic Wave Technology Sensors

Acoustic wave devices have been in commercial use for more than 60 years. The telecommunications industry is the largest consumer, accounting for ~3 billion acoustic wave filters annually, primarily in mobile cell phones and base stations.

These are typically surface acoustic wave (SAW) devices, and act as bandpass filters in both the radio frequency and intermediate frequency sections of the transceiver electronics. Several of the emerging applications for acoustic wave devices as sensors may eventually equal the demand of the telecommunications market.

INTRODUCTION TO BIOMECHANICS (BASIC DEFINITIONS) MUST KNOW

Definitions

Bio mechanics – application of the principles of mechanics / physics to biological organisms
muscle action vs. function
- action – motions produced by a muscle’s shortening; described in reference to axes and planes of body
  - – determined by architecture of joint and position of muscle around it
  - – pure mechanics which can be inferred
- function – how the organism chooses to use a muscle
  - – can involve positive, negative or non- work (see below)
agonists (Gr., contestant)– muscles with an identical action; usually restricted to single axis or plane of reference
