Ultrasound has been used in medicine for at least 50 years. Its current importance can be judged by the fact that, of all the various kinds of diagnostic images produced in the world, 1 in 4 is an ultrasound scan. Ultrasound energy is exactly like sound energy, it is a variation in ...
In examinations using external energy sources such as X-rays, ultrasound and injected radioactive substances, the information contained in the images is produced by the interaction between the energy and the organ under examination. This interaction can be visualized in two different ways: an image ...

Basic Principles and Technology Abstract Ultrasound was introduced as a new tool in medical diagnosis in 1947. This technology is based on transmission of high-frequency sound waves or pressure waves through a medium. Unlike electromagnetic waves, sound waves cannot be transmitted through a vacuum or...

The lecture will cover the basic principles of image acquisition. Since multiple ultrasound modes are used during the examination, the examiner has to be familiar with the advantages and disadvantages of these modalities in order to accurately use this diagnostic method. Besides under- standing the ...
