Improved estimation of the temporal decay function of in vivo metabolite signals

MRI-scanners enable non-invasive, in vivo quantitation of metabolites in, e.g., the brain of a patient. Among other things, this requires adequate estimation of the unknown temporal decay function of the complex-valued signal emanating from the metabolites. We propose a method to render a current decay estimator more simple, accurate, and robust...

Java/JNI/C/Fortran makefile project for a Java plug-in and related Android app in Eclipse ADT bundle: A side-by-side comparison

We have developed a Java/Fortran based application, called MonteCarlo, that enables the users can carry out Monte Carlo studies in the field of in vivo MRS. The application is supposed to be used as a tool for the jMRUI platform, being the in vivo MRS software system of the TRANSACT European Union project. The MonteCarlo application can be...

Simulating Metabolite Basis Sets for in vivo MRS Quantification; Incorporating details of the PRESS Pulse Sequence by means of the GAMMA C++ library

In this work we report on generating/using simulated metabolite basis sets for the quantification of in vivo MRS signals, assuming that they have been acquired by using the PRESS pulse sequence. To that end we have employed the classes and functions of the GAMMA C++ library. By using several versions of our PRESS-simulation program, we were able...
