A general model for head and neck auto-segmentation with patient pre-treatment imaging during adaptive radiation therapy. [PDF]
Med PhysAbstract Background During head and neck (HN) radiation therapy, patients may undergo anatomical changes due to tumor shrinkage or weight loss. For these patients, adaptive radiation therapy (ART) is required to correct treatment plans and to ensure that the prescribed radiation dose is delivered to the tumor while minimizing dose to the surrounding ...

Simulation of Skeletal Muscles in Real-Time with Parallel Computing in GPU
Applied Sciences, 2020 Modeling and simulation of the skeletal muscles are usually solved using the Finite Element method (FEM) which, although accurate, commonly needs a complex mesh and the solution is not processed in real-time. In this work, a meshfree model that simulates

Algorithmic GPGPU memory optimization [PDF]
2013 International SoC Design Conference (ISOCC), 2013 The performance of General-Purpose computation on Graphics Processing Units (GPGPU) is heavily dependent on the memory access behavior. In this paper, we present an algorithmic methodology to semi-automatically find the best mapping of memory accesses present in serial loop nest to underlying data-parallel architectures based on a comprehensive static ...

A GPU-based Monte Carlo model for water radiolysis under ultra-high dose rate irradiation: Development and validation with MPEXS2.1-DNA. [PDF]
Med PhysAbstract Background FLASH radiotherapy using ultra‐high dose rates (UHDR, > 40 Gy/s) demonstrates significant healthy‐tissue sparing while maintaining tumor‐control effectiveness. However, the underlying mechanisms remain unclear, with hypotheses suggesting that reductions in reactive oxygen species (ROS) yields could contribute to the FLASH effect ...
