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?
