Background: The aim of conservative surgery for treatment of breast cancer is obtaining satisfactory aesthetic results. Segment-based surgery, which must be followed by radiotherapy (RT), is considered the treatment of choice for most breast cancer patients. Single-dose intraoperative radiation in the tumor bed (IORT) is a promising radiation technique that is more rapid than conventional RT an...

The aim of this study was to perform a detailed analysis of the air kerma values around a Liac mobile linear accelerator working in a conventional operating room (OR) for IORT. The Liac delivers electron beams at 4, 6, 8 and 10 MeV. A radiation survey to determine photon leakage and scatter consisted of air kerma measurements on a spherical surface of 1.5 m radius, centered on the titanium exit...

Background: Intraoperative Irradiation Therapy (IORT) refers to the delivery of radiation during surgery and needs computed- thickness target as one most significant factors. Objective: This paper aimed compute design a pattern distributing irradiation uniformly throughout target.Material Methods: The Monte Carlo code was used simulate experimental setup in this simulation study. electron flux ...

BACKGROUND Promoting national health research agendas in low- and middle-income countries (LMICs) requires adequate numbers of individuals with skills to initiate and conduct research. Recently, non-governmental organizations (NGOs) have joined research capacity building efforts to increase research leadership by LMIC nationals. Partners In Health, an international NGO operating in Rwanda, impl...

Multi-layered communication networks including satellites and unmanned aerial vehicles (UAVs) with remote sensing capability are expected to be an essential part of next-generation wireless systems. It has been reported that deep reinforcement learning algorithm brings performance improvement in various practical environments. However, it is anticipated the computational complexity will a criti...
