Body Scans And Bottlenecks Case Solution & Answer

 Body Scans And Bottlenecks Case Solution


Dr. Steve Foster had higher position in radiology department, a mid-west hospital was taking different steps on maximizing the efficiency of its CT scanners. The hospital has been using 6 CT scanners that taken more of the worker’s time as compared to the time taken by the nurses. The new scanners were adopted by the hospital with value of $2 million per scanner. CT scanners were purchased to cut back the period and costs per scan, by providing a high resolution images within pace i.e. five times faster than the old scanning systems. But, the workers are unable to require the complete advantage of those systems because the time taken by a technician was the longest lag or bottleneck per scan. The hospital’s management had to specialize in changing the processes to require the fullest advantage of the new systems, through their speedy scanning capabilities.


The radiology department of the Mid-west hospital within the use of yank has been using the CT scanners, centered on the old technology, to perform numbers of CT scan over a period of 1998 -2001. The six scanning units were used through different shifts to deal with 550000 patients. However, the entire time taken by each scan process was 32 units, because of units were supported old technology.

The whole scanning process was supported three components i.e. preparation of patient, actual scan, and therefore, the construction of scanned images, therefore, the whole process was administered by one nurse and one technician, whereby a technician had to offer a complete 17 minutes for scanning, which was an opportunity for the nurse. So, these while lags were leading operational inefficiency and better costs for the hospital.

However, in 2005, after considering the lower profitability and operational inefficiencies, the management of the hospital invested $2 million each in 3 new multi-detector CT scanners, which increased operational efficiency and reduced the scanning time by five times as compared to the 32 minutes’ lengthy process by the old systems. The key concern of the management was to justify the prices with the increased benefit’s provided by the new systems. The new scanners were purchased to exchange the six old scanners because the scanning completion period of 32 minutes was very long. New scanners were assumed to scale back the scanning time also because the time, taken by a technician in performing one scan. Dr. Foster is encountered with many challenges while leaning out processes that are set in situ in order that inefficiencies are often removed while developing a replacement process.

Analysis– Old Version v/s New Version

The case was analyzed by checking out the operational inefficiencies or the bottleneck within the overall scanning process. The project management and operational management tools had been wont to analyze the scanning time, efficiencies, number of shifts and therefore, the related costs, i.e. the operational expenses per scan. Afterwards, the method capacity of the new CT scanners was calculated and compared with the first figures to work out the bottlenecks, and proposals in improving the method. Lastly, the case was concluded with possible costs and benefits of adopting new technological systems and proposals to require the fullest advantage of the fast CT scanners.

Old Scanners

The CT scanning process using the old systems wont to take 32 minutes per scan. The components of the scanning process are given as below with time taken by each step of the scanning process

  • Locating the patient within the lounge by a nurse is 2 minutes
  • Moving the patient towards the CT scanning room by a nurse is 2 minutes
  • Placing IV line for the contrast injection by nurse is 2 minutes
  • Setting up the CT scan protocol and constructing the machine by technical team is 3 minutes.
  • Performing CT scan takes 17 minutes.
  • Monitoring the reconstruction of CT image takes 10 minutes
  • Assisting to patients in getting off the table by nurse is 1 minute
  • Taking patient back to lounge by nurse takes 2 minutes
  • Changing the linen and cleaning the scan room by nurse is 2 minutes
  • Refilling the contrast injector by nurse takes 3 minutes
  • Coding and distributing the CT scan by the technician takes 2 minutes

Shortcomings of Old Scanning process

The complete scanning process demonstrated that technician was occupying 18 minutes quite a nurse per patient, and therefore, the 18 minutes’ period was an opportunity for the nurse. These 18 minutes had created bottleneck within the scanning process, ultimately resulting in reduced profitability and operational inefficiency. Both the nurse and therefore, the technician had been performing several responsibilities, but the time taken by the technician was greater by 18 minutes, thanks to older CT scanners…………………..
