Description of activity and work performed
Project 1
Analysis of procedures for head,
chest and abdominal CT scans,
from different vendors.
Objectives:
- To achieve CT procedures harmonization;
- To obtain dose reduction;
- To obtain adequate image quality considering the clinical task.
Results:
A dose reduction of 10,
36 and 10%,
respectively in head,
chest and abdominal CT scans was achieved,
whilst maintaining adequate objective and subjective image quality and harmonising procedures.
Project 2
Analysis of overexposed areas in paediatric plain radiography
Objectives:
- To compare the beam collimation with electronic collimation in chest,
abdomen and pelvis paediatric plain radiographs and quantify the over exposed areas.
- To analyse the impact of beam collimation in DAP values in paediatrics.
Results:
Average overexposure of 13,
16 and 23% was found in chest,
abdomen and pelvis radiography,
respectively.
Correction actions were implemented to avoid/decrease the overexposure.
Project 3
Analyse exposure data of dental panoramic and cephalometric imaging procedures
Objectives:
- To establish local DRLs for dental panoramic procedures
- To establish local DRLs for cephalometric procedures
