Storage Management: short time vs. long time; Role of compression

‘APAX VIEWER' is software that enables you to see the various medical images. It allows doctors in each clinical part to inquire about the medical images and helps them to diagnose their patient's illness more correctly. Its function related to the management of the database helps the doctors to prepare for the education, research and conference as well as to save the images into their personal computers. And it also can help the doctors to manage effectively the patient's data of diagnosis and treatment, connected with the Hospital Infor-mation System (HIS)."n‘APAX SERVER' is software that connects RIS to modalities, acquires images, archives images and interpretations with or without compression using multiple storage spaces."nAPAX Acquisition Server is a product that combined these functions into a single module, and provides flexibility by being compatible with any other device. Images managed with DICOM Server can be viewed through APAX Viewer."nThe DB composition is made up of exam information, image information, and deciphering results received through RIS I/F. Images are saved using 30:1 lossy compression (Wavelet) to maximize storage space, and the saved images and exam information are automatically deleted due to aging. To search deleted images, inquiry them through DICOM Query and import the images."nArchiving Server is for limited storage. The data, which is acquired recently, is stored in the Short-term Storage and when it passes defined days it will be moved to the Long-term Storage. The Short-term Storage used fast device (hard disks), while the Long-term Storage used cheap devices."nAPAX Storage Server checks multiple storage spaces any time, and assists Acquisition Server se-lecting a suitable storage space to store."nAPAX can compress data in Short-term and Long-term storage devices using Jpeg compression types (Lossy, Lossless, 2000 Lossy, 2000 Lossless) to reduce image size, which leads to increase storage capacity
