1. Medical Physics

2. A survey…
How many schools here have decided to choose the Elective: Medical Physics ?
How many schools here have decided NOT to choose the Elective: Medical Physics ?
Why ? Why NOT ?

3. fear… worry… Ignore it …
My sharing…
fear…
Two years ago, when first meeting Medical Physics, I …
worry…
Ignore it …

4. I will probably choose Medical Physics as one of the Elective.
But now…
I will probably choose Medical Physics as one of the Elective.
Why?

5. Curriculum (a): Making sense of the eye and the ear
- basic structure of the eye
- cone cells and rod cells
- spectral response
- resolving power
- accommodation

6. Curriculum (a): Making sense of the eye and the ear
- power of lens
- near point and far point
- defects of vision and corrections

7. Curriculum (a): Making sense of the eye and the ear
- basic structure of ear
- middle ear  pressure amplification
- inner ear  frequency discrimination
- sound intensity level
- curves of equal loudness
- noise

8. Some teachers may think that…

Biology?  

9. Advantage/disadvantage (1)?
Advantages:
Disadvantages:
Students also taking Biology may have an advantage. (Background knowledge)
Involves many Biological / Medical terms.
Topics relevant to student’s life.
Quite demanding on writing skills.
Many resources are already available from Biology teachers.

10. Curriculum (b): Medical imaging using non-ionizing radiation
Ultrasound:
- piezoelectric effect
- acoustic impedance
- intensity reflection coefficient
- attenuation of ultrasound
- A- scan (A = amplitude)
- B- scan (B = brightness)
- identify suitable frequency
- Advantages and limitation

11. Curriculum (b): Medical imaging using non-ionizing radiation
Fibre optic endoscopy:
- characteristic of optical fibre
- How fibre optic endoscope works
- coherent bundle fibres / incoherent bundle fibres
- Advantages and limitation

12. Some teachers may think that…

15. Advantage/disadvantage?
Advantages:
Disadvantages:
Most topics are new to teachers
Most topics are not difficult for teacher/students to understand.
Quite demanding on writing skills.
Include not many calculations and they are not difficult.
Only a few experiments and activities can be done in school.
Topics relevant to student’s life

16. Curriculum (c): Medical imaging using ionizing radiation
X-ray
radiographic imaging
Curriculum (c): Medical imaging using ionizing radiation
CT Scan
Radionuclide for
medical uses
