Figure 1.
The median effective dose and number of examinations per quarter year in mSv for aortic CTA examinations.
With the introduction the IR system (between 1/11 and 2/11) a significant reduction in radiation exposure can be reported.
Figure 2.
The median effective dose and number of examinations per quarter year in mSv for pulmonary CTA examinations.
The effective dose drops significantly in the last reported quarter, since the protocol was switched from 120kv to 100kv.
Figure 3.
The median effective dose and number of examinations per quarter year in mSv for thorax-abdomen-pelvis CT examinations.
With the introduction the IR system (between 1/11 and 2/11) a significant reduction in radiation exposure can be reported. The clinical value of a DMS is demonstrated with the increase in effective dose in 4/11 and the direct detection and correction.
Figure 4.
The median effective dose and number of examinations per quarter year in mSv for low dose scans of the cranial (for example sinuses).
Note it is important to point out that for unenhanced neurological CT scan the effect of IR in combination with a wide-detector configuration is naturally minor.
Figure 5.
The median effective dose and number of examinations per quarter year in mSv for all examination between January 2010 and December 2012.
With the introduction the IR system (between 1/11 and 2/11) a significant reduction in radiation exposure can be reported.
