Managing DICOM images: Tips and tricks for the radiologist.
RadiAnt Viewer is a DICOM image viewer with following features: Open and view DICOM files o Mono-frame and multi-frame, monochrome, RGB o Uncompressed, RLE, JPEG Lossy, JPEG Lossless, JPEG2000. Simple and intuitive interface. Zooming and panning.
Most DICOM images contain a description of bit depth that may be considered as the “nominal” bit depth, but this may be artificially large for computing compression ratios. For example, most MR images have a nominal bit depth of 16, though the actual pixel values may be encoded in fewer bits.
The following topics provide general information about the DICOM File Format. It is designed to help you become familiar with DICOM. For more detailed information on the DICOM File Format, you should refer to the DICOM Standard, published by.
A Transfer Syntax is a set of encoding rules able to unambiguously represent one or more Abstract Syntaxes. In particular, it allows communicating Application Entities to negotiate common encoding techniques they both support (e.g., byte ordering, compression, etc.).
The file extensions can be .dcm, .dcm30, .dicom. JPG (JPEG Image) is a lossy image compression format, compression method is usually lossy, based on the discrete cosine transform (DCT), encodings include: Sequential Encoding, Progressive Encoding, Lossless Encoding and Hierarchical Encoding. The file extensions can be .jpg, .jpeg, .jp2.
DICOM provides a mechanism for supporting the use of JPEG Image Compression through the Encapsulated Format. It defines a number of Transfer Syntaxes which reference the JPEG Standard and provide a number of lossless (bit preserving) and lossy compression schemes.
DICOM viewer. MicroDicom is a free DICOM viewer. Export to the most common picture formats, movie, clipboard. It is equipped with most common tools for manipulation of DICOM images.
