New features and changes introduced in this version are
The toolbox includes the following enhancements to the DICOM functions:
The dicomwrite function can now write data in any modality that can be read using dicomread. Note, however, that when writing data in these modalities, dicomwrite does not verify the data or check to see if the correct amount of data is written.
The toolbox can now read and write private metadata, even if they are not defined in the DICOM data dictionary. When private metadata is not in the data dictionary, dicomread uses generic names for the metadata fields, rather than the descriptive names available to attributes defined in the data dictionary.
You can create a custom data dictionary that contains definitions of your private metadata, using the dicomdict function.
The DICOM data dictionary changed so that some words are different now than in previous releases. This is due to updates in the data dictionary as defined by the DICOM standards committee.
The Image Processing Toolbox 4.2 includes the following bug fixes:
The bwdist function now produces correct results for very large images (such as 10000-by-5000).
The dicomread function no longer produces the "Error using reshape" message when reading a DICOM file containing multiframe data and overlays stored in both the pixel data and in the metadata.
The dicomwrite function can now correctly handle data attributes with multiple VMs (value multiplicity).
The dicomwrite function now produces correct results for the RLE (run-length encoding) compression type when the number of bits per pixel is greater than 8.
The im2col function, when called with the syntax im2col(1:N, [1 N]), now returns a column vector.
The imview function, when called with the syntax imview(I,[]), where I is a constant image, no longer produces a warning message about a badly conditioned polynomial.
The montage function no longer displays an extra blank row when displaying certain multiples of images.
The poly2mask function no longer errors when trying to close certain polygons, specifically polygons where the last element of vector X doesn't match the first element, x(1) ~= x(end), and the last element of vector Y matches the first, y(1) == y(end), or vice versa.
The stretchlim function now uses more bins to achieve better results for input images of class uint16 or double.
