dcm4che2 is an open-source collection of applications and utilities for healthcare entities handling, storing, printing, and transmitting information in medical imaging. Like its predecessor "dcm4che," this software utilizes the DICOM (Digital Imaging and Communications in Medicine) standard.

Product history

Around 2000, software developer Gunter Zeilinger wrote the code for JDicom, a popular DICOM application suite for handling and troubleshooting digital imaging processes. However, Zeilinger's experience using the Java DICOM Toolkit (JDT) to create JDicom led him to create his own Java-based DICOM toolkit. dcm4che was the end result, with the "che" part of the name supposedly being "inspired by the revolutionary nature of open source," and thus the revolutionary Che Guevara.^[2] Intended as a JSR (Java Specification Request) as a standard Java-based DICOM API, the toolkit took on greater popularity within the Java DICOM development community.

By 2006, however, Zeilinger saw a greater need for a more streamlined and memory-friendly version of the software.^[2] On May 31, 2006, the first open-source version of dmc4che2 saw light as version 2.0.5.^[1] Since then developmental revisions have occurred at a mostly steady pace, slowing down in progress by 2011. The latest version is 2.0.26, released on January 24, 2012.^[1]
