The use of the iPODs and flash drives for storage of gigabyte-size images has been investigated by several medical institutions worldwide. The storage and analysis of these images necessitates expensive image workstations. Concomitantly, multidimensional imaging techniques have presented new challenges, particularly in handling gigabyte-size images from CT, MRI and PET scanners, which generate thousands of images. In the field of diagnostic radiological imaging, the transition from analog to digital was closely followed by the development of the picture archiving and communication system (PACS). Other recent advancements using iPHONE and improved but expensive computers, integrated with picture archiving and communication system (PACS) as well as radiology and hospital information system (RHIS) for versatile applications in modern radiology, are also highlighted.This system, assembled with indigenous equipments, is much less expensive and specially suited for teaching radiologists, physicists and technologists, particularly in developing countries. It has good potential for use in clinical diagnosis as well. The system will be highly useful for storage and remote display of multitude of images from several modalities in the hospital, as well as other images, from the point of view of education and training. The image quality has been tested with dynamic and static medical images. The quality assurance (QA) of the displays has been successfully carried out with standard test patterns. The operational features and the advantages of these devices are discussed in detail. A TV image viewing unit is also provided. Through the use of a computer, these devices can access/ store/ display the images/ photos from a CD, digital camera or the internet. The iPOD, in addition, can display with sufficient resolution any of these images and serves as a transportable preview device. Both the iPOD and flash drive enable storage of thousands of images from diverse medical-imaging equipments. A locally assembled image viewer system with pocket-size iPOD (80 GB) and flash (2 GB) drives for gigabyte storage, display and transfer of digital medical images, oriented towards training purposes, is described.
