3. (One technique) Section 2: Pictorial section. Each question consists of a picture. Do the following: i) name the one or two phenomenon/a or the technique/s depicted therein - use the correct term/s- and ii) provide a short description of this/these, while indicating specifically how it/they relate/s to medical imaging. 4 points each; 20 points total. 1. (Two phenomena: encapsulated in green and red) Relative output Energy (key) 4. (One technique) 2. J(One important aspect of an imaging modality, encapsulated in red) x-y plane Signal Amplitude Receiver Coil

Explanation / Answer

1.answer. the relative output of any person will be high when there is influx of potassium ions,i.e the energy required to produce a particular task will increase initially and drops down slowly after a small duration.

2.answer.in MRI imaging the signal itself is oscillating in the MHz range (the resonance frequency)

signal amplitude and wavelength are gradually reducing with increasing time.and finally reaches to zero.

4.answer.computerized tomography of the saggital section of the brain taken in three transverse planes T1,T2,T3
