Frequently Asked Questions

What sort of data does Quantiphyse expect
Quantiphyse is designed for 3D medical imaging volumes. This might include imaging data, but also 3D volumes that define an ROI (binary values) or multiple ROI (integer/multi-level values). Quantiphyse recognises 4D (3+1D) imaging data as being three spatial dimensions and a fourth dimension of serial measurements at each 3D location - this would include timeseries data. This would be the normal format for use with many of the quantitative physiological image analysis tools, where multiple different measurements are needed to extract the relevant information. Quantiphyse can handle the special case of 2+1D data, i.e., a single slice of series data.
What file-types does Quantiphyse support
Quantiphyse directly supports Nifti volumes (both .nii and .nii.gz). There is some limited (and mainly experimental support) DICOM. But, if you have DICOM data we would suggest converting to Nifti yourself first.
How does Quantiphyse data defined on different grids/with different resolutions
Quantiphyse keeps all data on its original grad. But, for display purposes it will be interpolated onto the gird of the main data where necessary. Additionally, where an tool requires multiple data sources to be on the same grid to perform an analysis, interpolation will be used, the grid being determined by the tool.

Courses, Training & Demos

We run a variety of courses, workshops and demonstrations to introduce physiological image analysis techniques and offer hands-on experience with Quantiphyse. See below for recent and upcoming events.
