European regulation stress the importance of optimization ininterventional practices .The International Commission on Radiological Protection (ICRP) recommends adopting an integral approach for radiation protection during interventional procedures and auditing not only patient doses but also occupational doses , while never losing sight of the clinical outcome in any medical procedure. Manufacturers of X-ray and imaging systems have also madeimportant efforts to optimize their products by improving the post-processing of the images and making it possible to reduce the patient doses by more than 50% while...
Description of activity and work performed
Measurement of patient and scatter dose were performed in three catheterization rooms dedicated to interventional cardiology. Two of the interventional laboratories are Allura Xper models and the third one is an Allura Clarity (all from Philips Healthcare). All three have the same image detector and X-ray tube and quite a similar generator. The main difference between the Allura Xper model and the Allura Clarity is that the latter has an additional functionality (hardware and software) that can provide an important patient dose reduction [3-10]. This...
Conclusion and recommendations
In interventional practices, “dose reduction” systems using high filtration X-ray beams can provide an important reduction in patient dose indicators. Their use should be encouraged in interventional rooms whenever the image quality provided gives enough clinical information. But it is also important to note that they may not provide reduction in scatter dose for operators. Therefore, interventionalists must not overlook personal protection even when working with patient dose reduction systems.
