Aqual2 (A-cceptance QUAL-ification tool)

Analysis tool to extract geometric and contrast informmation from ADNI phantom scans

Features

Description

Aqual2 is an analysis tool for extracting geometric and contrast information from ADNI phantom scans.

Usage

System Requirements

Installation

  • In order to run Aqual2 you will need a recent version of Matlab (2006b is known to work).
  • Aqual2 has been developed for the Linux platform and may work under Windows and MacOS but these platforms have been invalidated.
  • Input images must be NIFTI-1 formatted, T1-weighted dense 3D volumes completely covering the phantom. The NIFTI input is assumed to have a valid "qform" transformation and that transformation is assumed to co-locate the image origin and MRI system isocenter.

Purpose

Two output streams are provided. Text output provides detailed information on geometric and contrast performance. Pdf output provides summary output to allow rapid qualitative evaluation of scanner geometric fidelity. Aqual2 has been developed against the database of ADNI phantom scans and is used in ADNI production processing.
