In acquiring a sequential CT image, the combination of X-ray tube and detector rotates as one unit to cover the 360 ̊ around the patient. (a) If the data has been acquired using 1800 projections, what is the angle that each projection covers? (b) If the CT gantry rotates one full cycle in 0.7 seconds, how long does it take to complete the data acquisition for each projection? (c) If there are 25 slices to be acquired, how long does it take to complete the total imaging session?

The office receives 110 customers per hour. All customers first see a receptionist. The receptionist directs them in one of three directions. 75 percent go directly to Issue License (staffed by 9 workers) where a new photo and license are done. 15 percent are required to take an eye test (staffed by one worker), and 10 percent must first take a multiple-choice electronic written test (on one of three computers). Only 85 percent of people pass the eye test and the remaining 15 percent exit. The customers who pass the eye test proceed on to the written test. 10 percent of the people who take the written test fail it, while 90 percent pass the test and then proceed to Issue License. The processing times of the stations are listed in the following table.
