Question

If a SPECT is being performed using a single head camera involving 64 projections and 52000 counts are collected during each 20-s stop, what are the total counts for the study and the total acquisition time?

a. 1 million cts, 20 mins
b. 1.1 million cts, 21 mins
c. 3.3 million cts, 21 mins
d. 3.3 million cts, 25 mins

Answer 1

The total counts for the study are 3,328,000 counts and the total acquisition time is approximately 21 minutes.

Step-by-step explanation:

To find the total counts for the study, we need to multiply the number of projections by the counts collected during each stop. So, 64 projections x 52,000 counts = 3,328,000 counts for the study.

To find the total acquisition time, we need to multiply the number of projections by the stop time. So, 64 projections x 20 seconds = 1,280 seconds. To convert this to minutes, we divide by 60, which gives us approximately 21 minutes.
