Titel:
Volume Constraint Denoising of Digital Subtraction Angiography Sequences
Abstract:
Digital Subtraction Angiography (DSA) using C-arm systems is a widely used imaging modality for the morphological and functional assessment of human vasculature. As 2D+t DSA sequences typically suffer from noise, the application of denoising algorithms is necessary for subsequent processing, e.g., in order to compute quantitative measures such as the Bolus Arrival Time (BAT). We propose a variational denoising method that accounts for the physics of the image formation process and preserves the...     »
