About our project  Why this project?  Planning  Introduction  Timetable  Data collecting and processing  Target values  Less than 2% rejects out of the total

Methods used to collect data  Collecting rejects  Collecting over a period of 2 weeks  A fill-in form with every reject  Differentiate between rooms and the time of day  Question list  We asked your opinion  Observation

Findings  Main cause  Differentiate between rooms  Total  Spoiled  Compared to total  Compared to target  Result question list  Not all results will be shown, if you are interested in all the results you should read our report.

Main cause (differentiate) Making the X-rayDeveloping

Main cause (total)

Spoiled compared to total GeneralA-block

Spoiled compared to target GeneralA-block

Result question list  83,3 % of the radiographers filled in the question list

What do you think is the main cause of the spoiled X-rays?

What is the average amount of X-rays you reject in a weeks time?

Experience of work pressure

What do you think of the exposures on the exposure factor list?

Result question list  Facts  There are a lot of experienced radiographers.  Every radiographer finds the quality of the x-rays. to be good  Most of the radiographers don’t think that there are too much rejects.  Almost all radiographers thinks there is too much work pressure, especially in the morning.

Conclusions  After processing the data we can conclude that the target set, isn’t reached by any part of the X- ray department. Yet every radiographer thinks the quality of the X-rays is well.  Exposure is the main cause of spoiled X-rays within this department. This is 66 %, so a clear majority.  Dark room errors are the second cause for the majority of rejects with a percentage of almost 23%.

Conclusions  In the morning most radiographers experience high work pressure.  In the afternoon the highest percentage of rejects occurs.  Out of the question list we can conclude that in most cases the exposure factor list isn’t used by the radiographers.

Recommendations  Repeat this project twice a year.  The radiographers should make better use of the exposure-factor list.  Improve the quality of the equipment of room 4.  Lower the work pressure especially in the morning.  Check the exposure factor list if it is still adequate.
