Example: VRs like CS (Code String) or DS (Decimal String) are directly encoded. The format is not important (Dicom or any format eg jpg, etc) but I need to know voxel dimensions/units and preferably the slice thickness would equal the slice spacing. For example, if the source instance refers to an instance in a Series, and the referenced instance is also converted, and hence placed in a new Series, then both the SOP Instance UID and the Series Reference UID in the hierarchical reference to the instance will need to be updated, as will the SOP Class UID of the referenced instance, if that Visible Female CT Datasets *All files now available on Harvard Dataverse. FileDataset corresponds to one slice of the CT scan. DICOM has been central to the development of modern radiological imaging: DICOM incorporates standards for imaging modalities such as radiography, ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), and radiation therapy. In order to keep the project manageable, it does not handle the specifics of individual SOP classes or other aspects of DICOM.

You are not authorized to redistribute or sell them, or use them for commercial purposes. The examples are standard PyTorch programs and have both dictionary-based and array-based transformation versions. My aim was to create a single DICOM per patient, and somehow keep the resolution for each image, but as per our previous discussion, this is not feasible in a single dataset, so I thought that maybe saving multiple dataset (each dataset with a specific resolution) would do the trick. The files need to be unzipped, use for example WinZip to decompress these files. When the database was released in 1997, computational resources to process hundreds or thousands of images were not widely Other libraries both inside and outside the pydicom organization are based on pydicom and provide support for other aspects of DICOM, and for more specific applications. dicom-microscopy-viewer - Vanilla JS library for web-based visualization of DICOM VL Whole Slide Microscopy Image datasets and derived information.
