Question

On a conventional, or serial, CT scan, if we want 5mm slices with 1mm of overlap, the table increment should be ___mm.

Answer 1

The table increment for the given CT scan is 4mm.

Step-by-step explanation:

The table increment, also known as the table feed per rotation, can be calculated using the following formula:

Table Increment = Desired Slice Thickness - Overlap

In this case, the desired slice thickness is 5mm and the overlap is 1mm. Plugging these values into the formula, we get:

Table Increment = 5mm - 1mm = 4mm

Therefore, the table increment should be 4mm.
