MRgFUS_software:
- Matlab code to control sonication real-time with baseline subtraction thermometry and a PID feedback controller
- V1: Single script version - intended for debugging purposes only
- V2: Modular software and GUI commented and tested - intended for use and straightforward modification
- ARFI folder: pulse sequence and recon code. C code must be compiled prior to use
- calcCEM_vect.m: computes thermal dose given focal temperature
- initFGEN.m: initializes waveform generator
- offFGEN.m: stops all waveform outputs to transducer
- parsepp.m: reads parameter file
- pidUpdate.m: PID controller computation
- readInFID.m: reads in next image from .fid data file
- runControlSoftware.m: master script, contains GUI to set up execution, begins sonication
- runExpGui.m/.fig: button to begin sonication
- runTempRecon.m: computes thermometry, calls other modules for execution
- userinterface.m/fig: optional GUI to set up sonication parameters
###MRgHIFU_hardware_pt#:
- Solidworks files and parts list of all hardware components used to build the system
- Split into 4 ".zip" files to comply with size requirements. Unzip into same folder for proper use.

Helpful tips:
- On the Varian systems, the current acquisition file can be found in '~/vnmrsys/exp2/acqfil/fid'
- Previously stored Varian data is found in'~/vnmrsys/data/studies/s_YYYYMMDD_##'
- Can run software in recon mode to see past execution
