things I may have missed

Question 1

what is kinematics

Answer 1

the study of rigid body motions and the associated forces

Question 2

what is the affine transform for rotation and translation

Answer 2

see notes

Question 3

what is the use of affine transforms in medicine

Answer 3

quantifying/mapping movement and images of movement can help classify normal movement and abnormalities
- only applied to rigid bodies (eg bones, cannot be applied to softer tissues such as intestines
- imaging errors can be reduced by repeat imaging from different centres, however it is difficult to position the patient the same way twice
