Q1. Using Exercise 3 in the slides as the starting point. Calculate the utilization (%) for the nurse, tech and CT scanner and calculate the process capacity if the technologist took 4 minutes of work from the nurse.

Q2. Comment on what other changes the hospital could possibly make.

Case Overview Dr. Steve Foster, head of radiology at a large, multidisciplinary hospital in the Midwestern United Stated, has to create a plan to maximize utilization of the 3 new CT scanner units purchased by his hospital. Each new scanner could provide high-resolution images in less than 7 minutes, compared to 32 minutes for the hospital's 6 older CT scanners. Foster needed to design a new process that would benefit the greatest number of patients and also maximize the return on the considerable financial investment of the new units represented. Process Flow for Original CT Scan Process Locate patient in waiting room Move patient into CT room Place IV line for contrast injection Assist patient off CT table Return patient to changing Change linen and clean CT Refill contrast injector area room Perform CT scan Select CT scan protocol and prepare scanner Reconstruc t CT image Code and distribute CT image Process Capacity Exercise 3 If the original process flows remained in place after the new CT scanners were installed, how many scans can be completed per hour? What is the utilization of each of the resources? Resource Unit Load (min) Capacity per hour Utilization (%) No. of Resource Units Total Resource Capacity Process Capacity per Hour Nurse 14 60/14 = 4.29 1 4.29 4.29/4.29 = 100 Tech. 6.5 9.23 1 9.23 4.29 46.4 6.5 9.23 1 9.23 46.4 Process Capacity Exercise 3 If the original process flows remained in place after the new CT scanners were installed, how many scans can be completed per hour?
