Image distribution within the operating room is a vexing problem of space restriction, data transformation. OR rooms are setup specifically for a given procedure with maximal attention given to surgical access to the field. Space is often not available for carts with monitors and floor level patch cords often cannot be used. Building and health code restrictions regulating OR construction and operation do not allow the same flexibility enjoyed in PACS deployment elsewhere in the medical center. Because of the many restrictions that exist In the OR environment, the costs of PACS deployment in the OR can become exorbitant. Wireless bandwidth standards have increased as 802.11b, 802.11a and 802.11g are adopted. The differences in range between 802.11a and 802.11g are addressed by adjusting the number of access points. Care must be given to the actual achievable wireless bandwidth and range as electrocautery devices that are widely used in ORs have been shown to decrease the effective wireless range by 50%. Use of techniques that maximally utilize low bandwidth transmissions such as progressive wavelet compression and other lossless compression schemes is important as the bandwidth restrictions of wireless networking are real. Many options exist for actual monitor mounting using the established Video Electronics Standards Association (VESA) Flat Panel Monitor Physical Mounting Interface (FPMPMI). The use of such standard interfaces allows multiple options to exist within an OR suite and the monitor mounting adjusted for different cases. Ceiling mounted cranes with VESA-FPMPMI attachments are also options that are available. Pointing device options begin with wireless keyboards and mice and extend to customized, dedicated, wireless or infrared 3D joysticks and other such niche products. Conclusion: OR image distribution solutions may range from the low cost to the high tech gadget type of approach. The requirements of the surgeons, budgetary restrictions and the creativity of the solution for each different OR room requires careful planning and a thorough investigation of all the available options.
1. Understand the needs and limitations of OR image distribution solutions 2. Understand the role of new technologies 3. Understand how to approach the design and implementation issues in the OR environment.
