Custom software written for various MRI quantification, computer simulation, as well as information related to MR hardware design and implementation.The programs below are developed in-house for pulse sequence design and image processing. All programs should be considered works in progress. Please email the respective authors with comments and errors.
T1rho/T2 processing GUI
This MatLab GUI will assist in processing T1rho- or T2-weighted images to create T1rho or T2 parametric maps. Software is compiled using MatLab 2007b and was tested on 2011b. Includes 2D in-plane co-registration Affine algorithms to correct for rigid-body distortions between data sets.

O2 Analysis – Analysis Software for 3He MRI
This software calculates regional VA/Q ratios from the regional measurements of PAO2 by a variation on methods used to calculate PAO2 from a known VA/Q ratio.

Shed – Automated parcellation of functional activation maps
Shed is a Matlab program designed to partition statistical activation maps into separate regions based on local peaks and cluster extents. Using a GUI interface, the program implements the watershedalgorithm to divide contiguous sub-regions of a statistical map without the need for manual intervention or user-bias.

SVS_B1cal – Calibrate the Transmit Reference Voltage on Siemens MRI scanners
SVS_B1cal is a Matlab program which determines the correct Transmit Reference voltage for an ROI specified by an SVS voxel. The program reads the spectroscopy signal from several SVS acquisitions acquired with varied transmit reference voltages. The program is designed to allow for quick transmit B1 calibration of a desired ROI.

RestLess – Real time monitoring of subject motion during fMRI scanning
RestLess is a Matlab program which monitors subject motion in real time during fMRI scanning on Siemens MRI scanners. The systems processes dicom images written in real time by the Siemens automated Dicom Export utility. It can display either absolute or relative subject motion and is capable of keeping up with TR times as fast as 1000ms.
