Effects of crystal size on the imaging performance using two collimator seri...Sin-di Lee
This study evaluated the effects of crystal size on imaging performance for two gamma camera models (Siemens Symbia and GE NM/CT 800) using Monte Carlo simulations. Different collimators from each model and two crystal thicknesses were tested with 99mTc, 67Ga, and 131I point sources in air and water. For 99mTc imaging, the GE ELEGP collimator provided equivalent sensitivity to the Siemens LEAP collimator but with better resolution. For 67Ga and 131I, the Siemens Medium collimator had better sensitivity but worse resolution than the GE ME collimator. A thicker crystal improved sensitivity for all radionuclides without significantly impacting resolution. The

Bone scan is widely used in surveillance of bone metastases for patients with prostate cancer. The aim of this study is to investigate the difference of the radiomic features based on Tc-99m MDP whole body bone scan in the metastatic bone lesions and degenerative change on vertebral bones.
This document summarizes a research project discussion meeting on December 31, 2013 presented by Sin-di Lee from the Kaohsiung Veterans General Hospital Department of Nuclear Medicine. The presentation introduced literature search tools including PubMed for article collection, interlibrary cooperation, Zotero for literature organization, and R for statistical analysis. It then demonstrated how to use PubMed filters and links, create accounts, save searches and subscribe to them. It also explained how to use Zotero and R for literature management, statistical analysis, and presentation of results.
This document discusses Wheelmap, an app and website that allows users to find wheelchair accessible locations by marking them as wheelchair accessible, limited accessibility, or not accessible. It provides links to download the Wheelmap app on iOS and Android as well as contact information for the developer to get involved in translating the app interface into Traditional Chinese. The summary ends with a request for volunteers to contact the developer to help with the Traditional Chinese localization effort.
