CESTsimu is a CEST simulation tool with a GUI for intuitively simulating spectral (1D Z-spectra) and spatial (2D phantom) data. CESTsimu has potential to broaden the utilization of CEST MRI among diverse users. It consists of three modules: Saturation settings, Exchange settings, and Phantom settings. CESTsimu can not only import/export files in the defined format but can also import files generated by other existing simulation platform (pulseq-CEST). CESTsimu has potential to facilitate the broad utilization of CEST MRI among diverse users.
- CESTsimu is developed using MATLAB 2024b, so if your version of MATLAB is earlier than 2024b, try update your MATLAB when encountering problems.
- In MATLAB, navigate to the CESTsimu folder, open CESTsimu.mlappinstall and install. Then you will find CESTsimu in the "Apps" tab, in the "My apps" group. Click on it to execute the app.
No additional MATLAB toolbox (e.g., Signal Processing Toolbox) is required for CESTsimu.
The source code of the CESTsimu is uploaded and named as CESTsimu_vxx.mlapp. You can customize the GUI using the MATLAB App Designer.
First open the .MLAPP file using the MATLAB App Designer, as follow:
Then you can modify the UI component in the Design View.
You can also switch to the Code View, and modify the Functions or the Callbacks.
