Real-time skin dose Radiation Monitoring during Coronary Angiography
The collective dose of radiation used in medical investigations and procedures has increased by greater than 700% between 1980 and 2006 [1]. Consequently the use of ionizing radiation has developed into an important, yet potentially avoidable, public health threat [2] that deserves considerable attention. This is particularly the case in adult cardiology patients where coronary angiography repr...
متن کاملReal-time colour pictorial radiation monitoring during coronary angiography: effect on patient peak skin and total dose during coronary angiography.
AIMS The aim of this study was to evaluate whether a real-time (RT) colour pictorial radiation dose monitoring system reduces patient skin and total radiation dose during coronary angiography and intervention. METHODS AND RESULTS Patient demographics, procedural variables and radiation parameters were recorded before and after institution of the RT skin dose recording system. Peak skin dose a...
متن کاملCerebral Autoregulation Real-Time Monitoring
Cerebral autoregulation is a mechanism which maintains constant cerebral blood flow (CBF) despite changes in mean arterial pressure (MAP). Assessing whether this mechanism is intact or impaired and determining its boundaries is important in many clinical settings, where primary or secondary injuries to the brain may occur. Herein we describe the development of a new ultrasound tagged near infra...
متن کاملStatus of eye lens radiation dose monitoring in European hospitals.
A questionnaire was developed by the members of WG12 of EURADOS in order to establish an overview of the current status of eye lens radiation dose monitoring in hospitals. The questionnaire was sent to medical physicists and radiation protection officers in hospitals across Europe. Specific topics were addressed in the questionnaire such as: knowledge of the proposed eye lens dose limit; monito...
متن کاملReal-time digital subtraction angiography for therapeutic neuroradiologic procedures.
Procedural control during therapeutic neuroradiologic procedures is generally based on repeated angiograms to assess the degree to which embolization has reduced abnormal blood flow. Due to the complex craniofacial skeletal anatomy that is superimposed over lesions in this area, subtraction studies are usually required to see the vessels and visualize a tumor stain satisfactorily. We have used ...
