Applications of physics are used in hospitals for both diagnosis and therapy. Whenever blood pressure (or temperature) is measured, an ECG recording is used, an endoscope is used, a scanner is used.
1 of 10
What is measured through physics in hospitals?
Blood pressure, ECG (electrocardiogram) potential differences generated by the heart and exposure to ionising radiation.
2 of 10
What is the disadvantage of using a CT scanner?
A CT scanner uses X-rays which are ionising radiation and can therefore damage living tissue.
3 of 10
What does an endoscope contain and why is it used?
Bundles of fibre optics and is used to look inside the body without making large incisions.
4 of 10
Why are X-rays used?
To take pictures of suspected broken bones.
5 of 10
Why are CT scanners used?
To build up digital pictures of a cross-section through the body.
6 of 10
Why are MR scanners used?
They use radio waves to produce detailed digital pictures of the body.
7 of 10
Which part of the electromagnet spectrum is used in a CT scanner?
X-rays.
8 of 10
Why do broken bones show up on X-rays?
X-rays are absorbed by bone.
