3.0.3

1. A new method for tensor calculation, Image Registration between theory and original DWI pairs, are implemented in this version. With this method, the original DWI will be co- registered with its theoretical one (which is derived from the estimated tensor and diffusion gradient) iteratively during tensor calculation process. Two methods, AIR and Mutual Information Registration, are available for image registration within this new method.
2. it now supports Philips Enhanced DICOM format, both in "MriView 3D" and "DTI Mapping" functions.
3. For Philips Enhanced DICOM files, the program can retrieve the gradients directly from their file header.

2010.06.18

ROIEditor

1.4.2

More digits are displayed when a pixel value is smaller than 0.01.

2010.03.23

DtiStudio

3.0.2

1. A new pixel-based outlier rejection method for tensor calculation. With this method, only the outlier pixels, not the outlier image slices, will be discarded during iterative tensor calculation. This method also takes account of the negative effects caused by mis-alignment between the image slices. By this new approach, the original image data points can be used as many as possible, and the signal to noise ratio of the results can be significantly improved.
2. it now supports Philips 4-dimensional DICOM format.
3. it now supports multiple-repetition Siemens Mosaic format.
4. for users convenient, some mostly used gradient tables are pre-defined as a user-selectable drop-down list within this updated program,
5. for Siemens Mosaic files, the program can retrieve the gradients directly from the file header.

2009.09.18

DiffeoMap

1.6

* Landmarker was renamed to DiffeoMap to represent its function more accurately.
* After the transformations, the updated images can be automatically saved.
* The buttons for all landmark-based transformations are moved to the tool panel.

2009.09.09

DtiStudio

3.0.1beta

1. DtiStudio can read NifTi single file format with "MRI View 3D" command now.Users don't need to convert NifTi into Analyze dual-files any more.
2. This updated version can read Big-Endian DICOM files. if the dataset is saved by a non-Intel machine (e.g. Motorola 68xxx), it may have a good chance that the DICOM files is in Big-Endian format. with this version, DtiStudio can rebuild this kind of images correctly.
3. Fiber file information displaying. When you try to load a pre-saved fiber data file (which was saved as default format) into current working-space using "File->Load Fiber Data" command, the fibers may not been able to overlaid onto the images correctly if the parameter of the fiber doesn't match with that of image. A pop-up message window will show the fiber parameters in such cases, to help uers locating the errors.
4. DtiStudio can save "Fiber Density Map" as a new kind of fiber tracking results. In this image map, each pixel contains the number of fibers passing through the pixels. So you can get a general idea about "fiber density" after fiber tracking from this image map. the density map can also be normalized into (0..1) by the biggest number of the fibers of all pixels. this function is available by clicking "Fiber-Save" button in the "Fiber" tab.
5. New method of tensor calculation. Pervious pixel-based automatic outlier rejection algorithm has been improved (thanks for Yue Li's significant contributions). The new algorithm uses weighted least-square regression model combined with error-points clustering approach, try to eliminate the bad pixels and minimize the square-errors by weighting the original signals based on the error-map between original and theoretical ones.

2009.05.29

ROIEditor

1.4.1

A bug was fixed. The feature "Exclude some pixels by setting the range of their intensities" now also works in the functions "Statistics for One ROI Object", "ROI Axial Profile", "ROI Sagittal Profile", "ROI Coronal Profile" and "Export Pixel Value".

2008.10.13

Landmarker

1.4

A bug was found in the tensor / vector reorientation algorithm of all the previous Landmarker versions, Version 1.0.1, Version 1.1, Version 1.1.1, Version 1.2 and Version 1.3.
* A bug affects the linear and non-linear registration of tensor data (*.d).
* When the transformation involves shearing operations, the tensor orientation was not properly re-oriented.
* This affects tractgraphy after registration.
* This does not affect scalar values such as FA, ADC, and eigenvalues.
* We strongly encourage you to download Version 1.4 and reprocess your registered images. For the reprocessing, you simply need to reapply the stored transformation matrices using the new version (Version 1.4) because transformation matrices are not affected by the bug.
