ABSTRACT
This chapter describes medical information systems, the details of picture archiving and communication system (PACS) and Digital Imaging and Communications in Medicine (DICOM). It presents medical steganography technique formulations and demonstrates their performance on medical images. The chapter provides the comparison metrics of medical image steganography. The development of computer systems has affected the healthcare industry. The electronic health record of a patient is a systematic collection of personal health information from birth to the time after death. PACS manages the software and platforms to acquire, store, distribute, and retrieve the medical images. In PACS, medical images are stored in DICOM file format. DICOM includes definitions for different devices, software, and platforms that are compatible with each other in PACS. In medical steganography, a cover object can be medical images or biological signals. The capacity of embedding message and robustness are essential problem for medical steganography application.
