Notifications and alerts in patient dose values for computed tomography and fluoroscopy-guided interventional procedures (original) (raw)
European Radiology
The terms “notifications” and “alerts” for medical exposures are used by several national and international organisations. Recommendations for CT scanners have been published by the American Association of Physicists in Medicine. Some interventional radiology societies as well as national authorities have also published dose notifications for fluoroscopy-guided interventional procedures. Notifications and alerts may also be useful for optimisation and to avoid unintended and accidental exposures. The main interest in using these values for high-dose procedures (CT and interventional) is to optimise imaging procedures, reducing the probability of stochastic effects and avoiding tissue reactions. Alerts in X-ray systems may be considered before procedures (as in CT), during procedures (in some interventional radiology systems), and after procedures, when the patient radiation dose results are known and processed. This review summarises the different uses of notifications and alerts to...

Radiation dose management in CT imaging: Initial experience with commercial dose watch software
Journal of Physics: Conference Series
In this study, a patient dose tracking software was utilised for the management patient doses and optimisation of scanning protocols for computed tomography (CT) imaging. This study aimed to evaluate the used of GE DoseWatch software for local dose tracking and management. The commercial DoseWatch software was first installed at Imaging Unit, Advanced Medical and Dental Institute, Universiti Sains Malaysia (AMDI, USM), Penang on November 2018. All the CT scans were tracked by this software connected on-line to the Siemens SOMATOM AS+ CT scanner and GE Discovery SPECT/CT scanner. A total of 361 CT dose dataset were evaluated during the period of 10 months started from November 2018 until August 2019. From the initial experience, this software allows rapid and reliable collection and management of the CT dose data involving large number of examinations. From comparative study with our established local dose reference level, the mean DLP for few CT protocols exceeded the LDRLs such as ...
