![]() (a) Extension of the DICOM model of the real world for specimens. Representation of digital pathology information in DICOM. By leveraging a wealth of existing infrastructure solutions, the use of DICOM facilitates enterprise integration and data exchange for digital pathology.Ĭomputational pathology DICOMweb image compression slide scanning whole slide imaging. Implementation of DICOM allows efficient access to image data as well as associated metadata. ![]() For lossless compression, JPEG-LS significantly outperforms JPEG 2000 with respect to data encoding and decoding speed. For lossy compression, JPEG achieves the fastest compression/decompression rates. Performance measurements show that the choice of image compression method has a major impact on data access efficiency. These objects can be accessed efficiently from files or through RESTful web services using existing software implementations. Whole slide image data can be encoded together with relevant patient and specimen-related metadata as DICOM objects. Finally, we evaluated storing, querying, and retrieving data over the web using existing DICOM archive software. ![]() We validated the generated DICOM files using recognized DICOM validation tools and measured encoding, storage, and access efficiency for three image compression methods. ![]() We generated the files using image data from four vendor-specific image file formats and clinical metadata from two departments with different laboratory information systems. We selected relevant DICOM attributes, developed a program that extracts pixel data and pixel-related metadata, integrated patient and specimen-related metadata, populated and encoded DICOM attributes, and stored DICOM files. Here, we implemented the essential aspects of the standard and assessed its capabilities and limitations in a multisite, multivendor healthcare network. A DICOM file format and communication protocol for pathology have been defined however, adoption by vendors and in the field is pending. Digital Imaging and Communications in Medicine (DICOM ®) is the standard for the representation, storage, and communication of medical images and related information.
