Final answer:
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.
