RESUMO
OBJECTIVE: With a 12-year background of our completely digital nuclear medicine picture archiving and communication system (PACS), we have recently implemented a novel PACS, OpenPACS, which can be used for interpretation and display of CT, MR imaging, sonography, nuclear medicine, and computed and digital radiography studies. OpenPACS uses low-cost standard PC hardware and software that is widely available and is readily serviced and maintained. The OpenPACS application program is available over the Internet. CT or MR imaging slices from one or multiple studies can be presented simultaneously or in cine mode on a wall-sized multimonitor display. The assembly, with a total resolution of 6400 x 4800 pixels, resembles a traditional array of eight standard X-ray viewboxes. A wireless mouse is used to vary attenuation and other display parameters. Multiple backup and redundancy are provided. Currently, six CT and six MR imaging scanners of different vendors are networked to OpenPACS, which is also networked to our nuclear medicine PACS. CONCLUSION: After only a brief introduction, radiologists rapidly become familiar with the system because it is based on the use of standard Windows icons and procedures and offers a display that resembles a standard X-ray film presentation.
