Most of the medical images (e.g. CT, MRI, PET, etc.) comprises multiple frames which represent slices, phases, timing etc. from the same imaging object. With the powerful support of multidimensional data representation, those images can be saved as multidimensional matrices in Matlab. However, within Matlab, most of image manipulation functions are limited or tailored for two-dimensional matrix. The MatrixUser is a matrix analysis software package which features functions designed and optimized specifically for manipulating multidimensional real or complex data matrix. Within a nice graphical representation, image analysis including multidimensional matrix display, matrix (image stack) processing and rendering can be conveniently accomplished with minimum efforts.
More specifically, MatrixUser features:
1. Multidimensional data import and conversion: Support importing and converting matrix data from MAT, NIFTI, DICOM, Clipboard and Screen Shot
2. Multidimensional matrix display: Support displaying multidimensional (1,2,3 and above) matrix and allow easily image switch between any dimension. Support profile inspection for a single voxel along any dimension. Support volume view with two additional orthogonal displays.
3. Image overlay: Allow overlay of two multidimensional matrices in studies such as fMRI, dynamic imaging and PET imaging, etc.
4. Matrix Manipulation: Allow convenient matrix truncation, concatenation and transform. Support multiple types of regular image processing (e.g. interpolation, spatial transformation, FFT, filtering and noise etc.)
5. Region-of-Interest and Segmentation: Allow convenient multislice ROI and segmentation analysis across the whole volume
6. Volume rendering: Support 3D volume rendering with easy parameter settings
7. Image representation: Provide functions for creating montage with multislice images, re-slicing matrix along any spatial direction, making image projection along arbitrary angle, creating movies and more
If you need a handy graphical matrix analyzer in Matlab, MatrixUser is designed for you and your studies. To run this program, simply run Main.m under the root folder. For more information, please also check
