책소개

In vivo magnetic resonance spectroscopy provides insight into metabolism in the
human body. New acquisition protocols are often proposed to improve the quality
or efficiency of data collection. Processing pipelines must also be developed to use
these data optimally. Current fitting software is either targeted at general
spectroscopy fitting, or for specific protocols. We therefore introduce the
MATLAB-based OXford Spectroscopy Analysis (OXSA) toolbox to allow researchers
to rapidly develop their own customised processing pipelines. The toolbox aims to
simplify development by: being easy to install and use; seamlessly importing
Siemens Digital Imaging and Communications in Medicine (DICOM) standard data;
allowing visualisation of spectroscopy data; offering a robust fitting routine;
flexibly specifying prior knowledge when fitting; and allowing batch processing of
spectra. This article demonstrates how each of these criteria have been fulfilled,
and gives technical details about the implementation in MATLAB. The code is
freely available to download from https://github.com/oxsatoolbox/oxsa.
