Medical applications of physics

name the different medical uses of
what is the equation for calculating speed?
If a dog travels at 10m/s for 2 mins, how far does it travel?

Uses of X-rays
CAT Scanner
X-Ray Therapy

a)Electronic systems can be used to produce
ultrasound waves, which have a frequency higher
than the upper limit of hearing for humans.

b) Ultrasound waves are partially reflected when they
meet a boundary between two different media.
The time taken for the reflections to reach a detector
can be used to determine how far away sucha boundary is
c) Calculation of the distance between interfaces
in various media.
s = v X t

d) Ultrasound waves can be used in medicine.
Additional Guidance
Candidates should know that the range of human hearing is about 20 Hz to 20000 Hz.
Candidates may be required to use data from diagrams of oscilloscope traces.

s is distance in metres, m
v is speed in metres per second, m/s
t is time in seconds, s

Examples include pre-natal scanning and the removal
of kidney stones.
