Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is not an advantage of Ultrasound examination
A
-must have a trained operator to be effective
B
-non ionising
C
-no/or little discomfort whilst procedure is taking place
D
-equipment is relatively cheap
Explanation: 

Detailed explanation-1: -Ultrasound imaging is extremely safe and does not use radiation. Ultrasound scanning gives a clear picture of soft tissues that do not show up well on x-ray images. Ultrasound is the preferred imaging modality for the diagnosis and monitoring of pregnant women and their unborn babies.

Detailed explanation-2: -Disadvantages of Ultrasonic Testing Techniques: More expensive than other methods. Difficult to use on thin materials. Part Geometry can cause complications. Needs relatively smooth surface to couple transducer.

Detailed explanation-3: -Increased depth means a lower frequency is required for optimal imaging. As a consequence there is a lower resolution. Anisotropy. Simply this means a structure is highly reflective to ultrasound. Bone blocks US waves. Artefacts are common. Training.

Detailed explanation-4: -Versatile imaging. Compared to X-rays, which are best for taking images of your bones, ultrasounds give us a better look at your soft tissues. Widely accessible. Noninvasive. Less risk. What you can expect.
