Question

Using a multifield image intensifier tube, which of the following input phosphor diameters will require the highest patient dose ?

A. 35 cm

B. 25 cm

C. 17 cm

D. 12 cm

Answer 1

A multifield image intensifier tube with a larger input phosphor diameter will require a higher patient dose.

Step-by-step explanation:

A multifield image intensifier tube is used in medical imaging to amplify and enhance low levels of light. The input phosphor diameter of the tube is important for determining the patient dose. The larger the input phosphor diameter, the higher the patient dose.

Therefore, among the given options, the input phosphor diameter of 35 cm (option A) will require the highest patient dose.
