Digital subtraction angiography images of data backup storage

L3 007 on the No. 2 JModClinMedBi0eng. A port ril2007. V0I13N0.2 general system configuration of PACS image workstation DSA are no corresponding subtraction processing software, resulting in a serious decline in the reliability of the image, making meaningless the backup PACS, and DVD and USB removable storage are fully using the same raw data and the same image processing software, so there is no change in image quality. In addition, PACS system is all digital imaging equipment storage center, not a single DSA image storage device, the storage cost per patient can not simply be calculated by 5000, so the cost of the other two methods can not make a reasonable contrast. PACS storage backup with backup speed, simple operation, but the backup of the image data can not meet the normal requirements and the high cost of diagnosis is the most prominent shortcomings. USB removable storage USB mobile hard disk is used by the USB mobile hard disk box with an ordinary desktop IDE hard disk drives, has the following characteristics: (1) transmission speed; (2) to expand capacity; (3) independent power supply, no external power supply; (4) connections, easy to operate; (5) reliability, versatility high; (6) to support multimedia j. The latest USB2.0 technology has the following characteristics: (1) is fully compatible with USB1.1 specification; (2) users of PC peripheral expansion is simple, hot-swappable; (3) to support 480Mbps transfer speeds, you can choose wide range of peripheral type; (4) low cost j. USB2.0 technologies, making the speed of mobile storage while the USB1.1 12Mbit / s upgrade to 480Mbit / s, 40 times the speed of a full upgrade. This makes high-speed mobile storage become a reality. With the development of hardware technology,[link widoczny dla zalogowanych], the emergence of large-capacity hard drives and hard drives continue to lower manufacturing costs, high-capacity USB mobile hard disk has gradually gained popularity. USB removable storage with good image quality,[link widoczny dla zalogowanych], easy to operate, the backup speed and low cost. However, USB removable storage there is limited scalability, interface power supply, low,[link widoczny dla zalogowanych], Windows98, and the following operating systems can not be achieved hassel boot and other defects. Table 2 can be seen through the backup and access to the image are the longest DVD, USB removable storage time-consuming the least. The most complex operation of DVD, USB removable storage easiest. The reliability of the worst PACS images, DVD and USB removable storage image quality is best. USB removable storage backup the lowest cost. In short,[link widoczny dla zalogowanych], the DVD is too complicated, time-consuming operation; PACS system,[link widoczny dla zalogowanych], the high price and lack of appropriate image processing software support, and the resulting its practicality is not high; coupled with the development of computer hardware technology and hardware to further reduce the cost of , USB removable storage technology is the hospital daily work of the simplest and most affordable DSA image data stored.
