3D-Localization of Single Point-Like Gamma Sources with a Coded Aperture Camera

Autor: Meißner, Tobias, Cerbone, Laura Antonia, Russo, Paolo, Nahm, Werner, Hesser, Jürgen

3D-localization of gamma sources has the potential to improve the outcome of radio-guided surgery. The goal of this paper is to analyze the localization accuracy for point-like sources with a single coded aperture camera. We both simulated and measur

Analysis of Weighted Fraction of Length for Interfacial Gap in Cervical Composite Restorations as a Function of the Number of B-Scans of OCT Volume Scans

Autor: Schneider, Hartmut, Meißner, Tobias, Rüger, Claudia, Haak, Rainer

In dental research, the morphometric assessment of restorations is a challenge. This also applies to the assessment of the length of interfacial adhesive defects in composite restorations as a measure of tooth-restoration bond failure. The determined

Assessment of the Axial Resolution of a Compact Gamma Camera with Coded Aperture Collimator

Autor: Meißner, Tobias, Cerbone, Laura Antonia, Russo, Paolo, Nahm, Werner, Hesser, Jürgen

Purpose: Handheld gamma cameras with coded aperture collimators are under investigation for intraoperative imaging in nuclear medicine. Coded apertures are a promising collimation technique for applications such as lymph node localization due to thei

Simulation Study on Super-Resolution for Coded Aperture Gamma Imaging

Autor: Meißner, Tobias, Nahm, Werner, Hesser, Jürgen, Löw, Nikolas

Coded Aperture Imaging (CAI) has been proposed as an alternative collimation technique in nuclear imaging. To maximize spatial resolution small pinholes in the coded aperture mask are required. However, a high-resolution detector is needed to correct
