Clinical commissioning of online seed matching protocol for prostate radiotherapy

Optimal Matching for Prostate Brachytherapy Seed Localization with Dimension Reduction

In prostate brachytherapy, x-ray fluoroscopy has been used for intra-operative dosimetry to provide qualitative assessment of implant quality. More recent developments have made possible 3D localization of the implanted radioactive seeds. This is usually modeled as an assignment problem and solved by resolving the correspondence of seeds. It is, however, NP-hard, and the problem is even harder ...

Auto-contouring the Prostate for Online Adaptive Radiotherapy

Among all the organs under cancer treatment, prostate is a very important one in male pelvic region but very difficult to segment, due to the poor contrast of 3D CT images, invisible boundaries between the prostate and its neighboring organs (e.g. bladder, rectum), and artifacts produced by prostate seeds etc. Furthermore, the same patient’s organ conditions (e.g. size, shape and location) can ...

Standard Operating Procedure: Clinical Commissioning Policy: The use of Stereotactic Ablative Radiotherapy (SABR) in the treatment of Prostate Cancer

A Decentralized Online Sortition Protocol

We propose a new online sortition protocol which is decentralized. We argue that our protocol has safety, fairness, randomness, non-reputation and openness properties. Sortition is a process that makes random decision and it is used in competitions and lotteries to determine who is the winner. In the real world, sortition is simply done using a lottery machine and all the participa...
