A patient dose-reduction technique for neuroendovascular image-guided interventions: Image quality comparison study

摘要

Background and PurposeThe ROI–dose-reduced intervention (ROI–DRI) technique represents an extension of ROI fluoroscopy combining x-ray entrance skin dose reduction with spatially different recursive temporal filtering to reduce excessive image noise in the dose-reduced periphery in real-time. The aim of our study was to compare the image quality of simulated neurointerventions with regular and reduced radiation doses using a standard flat-panel detector system.
