COTILab

COTILab specializes in high-performance computational photonics, translating academic research into GPU-accelerated simulation tools used by biophotonics engineers, medical-imaging scientists, and optical-system designers. Its flagship line, Monte Carlo eXtreme (MCX), delivers physically accurate photon-transport modeling that is orders of magnitude faster than CPU-based counterparts, enabling rapid iteration during the development of diffuse-optical-tomography systems, fluorescence-guided surgery devices, and wearable NIRS sensors. The same ray-tracing engine is embedded in MCX Studio, a cross-platform workbench that wraps scripting-level kernels behind interactive 3-D geometry editors, source-pattern wizards, spectral material libraries, and real-time fluence viewers. Researchers use the studio to benchmark new reconstruction algorithms against standardized digital phantoms, while clinicians exploit its batch mode to optimize source-detector fiber placements on patient-specific MRI meshes. Additional utilities export absorption-scattering maps to FE solvers, convert time-resolved data to HPC job arrays, and validate results against analytical solutions, streamlining regulatory documentation for FDA and CE submissions. Because the codebase is released under an open academic license, hardware vendors frequently bundle MCX benchmarks to demonstrate GPU scaling on workstations, cloud instances, and embedded CUDA boards. Users seeking turnkey access will find COTILab software available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the latest upstream build, and support unattended batch installation of multiple related applications.
