Question 9

Question
Radiographers take precautions to minimise the [blank_start]radiation[blank_end] [blank_start]dose[blank_end] from X-rays. They do this by wearing lead [blank_start]aprons[blank_end], or standing behind a lead [blank_start]screen[blank_end], or [blank_start]leaving[blank_end] the [blank_start]room[blank_end] while scans are being done. This reduces the [blank_start]exposure[blank_end] time, and provides shielding.

Question
Fill in the blanks about the safety and image quality of X-rays and ultrasound. SAFETY: [blank_start]Ultrasound[blank_end] is [blank_start]non-ionising[blank_end] and [blank_start]safe[blank_end]. They [blank_start]can[blank_end] be used on babies. [blank_start]X-rays[blank_end] are [blank_start]ionising[blank_end], and can cause [blank_start]genetic mutations[blank_end] which harm [blank_start]cells[blank_end]. They [blank_start]cannot[blank_end] be used on babies. CT scans use [blank_start]more[blank_end] [blank_start]X-rays[blank_end], so are [blank_start]more[blank_end] ionising. They [blank_start]increase[blank_end] the [blank_start]radiation dose[blank_end] even more. They [blank_start]cannot[blank_end] be used on babies. IMAGE QUALITY: [blank_start]Ultrasound[blank_end] images are usually [blank_start]fuzzy.[blank_end] [blank_start]X-ray[blank_end] images are [blank_start]clear[blank_end] if showing [blank_start]bone or metal[blank_end] - otherwise, they are [blank_start]fuzzy[blank_end]. CT scans are clear, [blank_start]three-dimensional[blank_end] and [blank_start]high-resolution[blank_end]. They can be used to diagnose [blank_start]complicated illnesses[blank_end].

Question 40

Question
CT scans use [blank_start]X-rays[blank_end] to produce high-[blank_start]resolution[blank_end] images of soft and hard [blank_start]tissue[blank_end]. The patient is put inside a [blank_start]cylindrical[blank_end] scanner, and an [blank_start]X-ray[blank_end] beam is fired through the body from an [blank_start]X-ray[blank_end] [blank_start]tube[blank_end] and is picked up by [blank_start]detectors[blank_end] on the other side. The tube and detectors are [blank_start]rotated[blank_end] throughout the scan. A computer interprets the signals from the detectors to produce a [blank_start]two-dimensional[blank_end] image.

Question 41

Question
X-rays can cause [blank_start]ionisation[blank_end] (i.e. they kill living cells), so can be used to treat [blank_start]cancer[blank_end]. The X-rays are focused on a [blank_start]tumour[blank_end] using a [blank_start]wide[blank_end] beam. This beam is rotated around the patient with the [blank_start]tumour[blank_end] at the centre. This minimises the [blank_start]exposure[blank_end] of normal cells to [blank_start]radiation[blank_end], so reduces the chances of the rest of the body being damaged.
Answer

  • cancer
  • tumour
  • wide

  • parallel
  • rays
  • principal
  • diverging
  • converging

Question 44

Question
If the angle of incidence is [blank_start]less than[blank_end] the critical angle, most of the light passes out but some light is internally [blank_start]reflected[blank_end]. If the angle of incidence is [blank_start]equal to[blank_end] the critical angle, the emerging ray comes out along the [blank_start]surface[blank_end] and more internal reflection occurs. If the angle of incidence is [blank_start]greater than[blank_end] the critical angle, no light comes out - it is [blank_start]totally[blank_end] [blank_start]internally[blank_end] reflected.
Answer
  • less than
  • equal to
  • greater than
  • reflected
  • surface
  • totally
  • internally
