What's New

MCX v2023 is a milestone release since v2020 released 3 years ago. It contains all
the new features introduced in the two previous unofficial releases, v2022.10 and v2021.2,
along with extensive continuous integration (CI) development and numerous bug fixes.

Specifically, MCX v2023 officially ships a major new feature - split-voxel MC (SVMC),
published in Biomedical Optics Express by Shijie Yan and Qianqian Fang, see
Yan2020 for details.
Shortly, SVMC provides a level of accuracy close to mesh-based MC (MMC) in modeling
curved boundaries but it is 4x to 6x faster than MMC. Several demo scripts of SVMC
can be found in the MCXLAB package under examples/demo_svmc_*. In addition, MCX v2023
supports GPU-based polarized light simulation, see our JBO paper
Yan2022. Moreover, an "RF replay"
algorithm was implemented by Pauliina Hirvi et al. to create frequency-domain (RF)
Jacobians for both amplitude and phase components. Please read the details in
Hirvi2023. This release
also includes both the web-client and server scripts for MCX Cloud - an in-browser MC
simulator as we reported in Fang2022. Lastly, MCX
v2023 provides an official Python mcx module (pmcx) to run stream-lined MCX simulations
in Python, offering mcxlab-like interface.

Starting in MCX v2023, we have completed the migration from MCX-specific binary output
formats (.mc2/.mch) to human-readable, extensible and future-proof JSON-based portable
data formats defined by the NeuroJSON project. The NeuroJSON
project aims at simplify scientific data exchange using portable data formats that are
readable, searchable, shareable, can be readily validated and served in the web and cloud.
The NeuroJSON project is also led by MCX's author, Dr. Qianqian Fang, funded by the
US NIH U24-NS124027 grant.

As a result of this migration, the MCX executable's default output formats are now
.jnii for volumetric output data, and .jdat for detected photon/trajectory data.
Both data formats are JSON compatible. Details on how to read/write these data files
can be found below.

In summary, v2023 is packed with exciting updates, including

Introduced Split voxel MC (SVMC) to accurately model curved boundaries
GPU polarized light modeling (Stokes) with 900x speedup
RF replay to build frequency-domain Jacobians for amplitude and phase
Web-based MCX Cloud platform including web-client and server scripts
pymcx - an mcxlab-like Python module for running MCX simulations in Python
Added Debian/Ubuntu packages for easy installation
Added a unified command line interface, photon, to call mcx/mcxcl/mmc
Fine-tuned Windows installer
Extensively developed Github Action for automated building and packaging of mcx
Adopted standardized NeuroJSON JNIfTI and JData formats to ease data exchange
New source types: hyperboloid and ring (annulus,annulus sector)
