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

Result question list
83,3 % of the radiographers filled in the question list
![Page 12: A project to find the main cause of rejected x-rays](https://reader036.vdocuments.us/reader036/viewer/2022062805/5697bfd91a28abf838cafbf1/html5/thumbnails/12.jpg)
What do you think is the main cause of the spoiled X-rays?
![Page 13: A project to find the main cause of rejected x-rays](https://reader036.vdocuments.us/reader036/viewer/2022062805/5697bfd91a28abf838cafbf1/html5/thumbnails/13.jpg)
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.
![Page 17: A project to find the main cause of rejected x-rays](https://reader036.vdocuments.us/reader036/viewer/2022062805/5697bfd91a28abf838cafbf1/html5/thumbnails/17.jpg)
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.
