Applied Science AQA/Imaging Methods

Context
... to be familiar with all of the diagnostic techniques available in the NHS.

Brief
In general, point students towards the approach to take, as opposed to just giving them information.

Advice
- pick two methods

- explain how they work to produce images (include diagrams)

- describe and explain suitable and unsuitable conditions for imaging with each technique - include example calculations to support your explanation of how the techniques work

Calculations
Setting out your Calculations for D1

1. Introduction - what you can work out and why it is useful.

(e.g. I will show the calculation of acoustic impedance because it is useful when...)

2. The equation (words or symbols) - and what the terms represent.

(e.g. write the equation here - when explaining the terms, it is useful to include units.)

3. Context - introducing the relevant numbers that you are going to use in your calculation.

(e.g. the density of bone is...; the speed ultrasound travels through bone is...)

4. Workings - showing how the numbers go into the equation.

(set this out clearly)

5. Answer - with units and a comment about what it means. e.g. what it tells you about the image quality or a comparison.

(e.g. this value is much higher than soft tissue, which tells us...; this number can then be used in the calculation of the reflection coefficient, which can tell us...)

Ideas for Calculations to Include

Research into these ideas - aim to include at least two different calculations for each imaging method to be sure of meeting the distinction criterion.
