RTPSpy

RTPSpy performs real-time processing of functional magnetic resonance imaging (fMRI) data to provide online denoising, anatomical segmentation, region-of-interest mask generation, pipeline simulation, and signal exchange for rtfMRI experiments and neuromodulation research.

Key Features:

• Online Noise Reduction: Fast, comprehensive online fMRI image processing modules perform denoising in real time with quality comparable to offline denoising techniques.
• Anatomical Image Processing: Integrates FastSurfer, ANTs, and AFNI for tissue segmentation and ROI mask creation, producing outputs comparable to FreeSurfer and executable in minutes.
• Pipeline Simulation System: Simulation framework for online fMRI processing that allows optimization of processing pipelines and target-signal calculations.
• External Application Integration: Signal exchange with external applications via TCP/IP sockets to enable interoperability with other software and devices.
• Modular Architecture: Modular components permit customization and combination of individual processing steps for varied rtfMRI workflows.

Scientific Applications:

• Real-time fMRI neurofeedback and neuromodulation: Supports implementation and evaluation of treatment-oriented and personalized neuromodulation protocols.
• Mechanistic brain imaging studies: Enables online analysis and ROI-based investigations for studies of brain function.
• Experimental protocol optimization: Uses pipeline simulation and target-signal calculations to optimize processing choices and experimental designs.
