TASK SPECIFIC EVALUATION METHODOLOGY FOR CLINICAL FULL FIELD DIGITAL MAMMOGRAPHY
… strategies and a variety of mathematical model observers in order to evaluate the performance of clinical FFDM systems under different conditions. To evaluate image acquisition performance, we tested a system-model-based Hotelling observer (SMHO) model on a bench-top system using a uniform …

Objective Assessment Methods for List Mode Imaging System
… of a medical imaging system, both the task and observer have to be well defined. The objective quality of the image depends on how well the specified observer can extract the desired information to perform the task. Classification or detection tasks are often considered in practice. Two commonly …

Implementation and Analysis of 3-D Tomographic Reconstructions from Space-Based Imaging Platforms
… reconstructions of the simulations, and using a Hotelling observer to determine the overall image quality. Tomographic reconstructions are found to be effective in many applications for space imaging. However, the severely limited projection angles do provide constraints on the overall …

Simultaneous ⁹⁹m̳Tc-MDP/¹²³I-MIBG imaging of neuroblastoma using SPECT-CT
… OSEM and MC-JOSEM, respectively. Channel Hotelling observer (CHO) was used to calculate lesion detectability. On average, the CHO SNR obtained from dual-isotope studies is close to that of single-isotope studies for each radionuclide. (SNR: 3.521 for dual-isotope versus 3.828 for …
