65 -- IMAGE MANAGEMENT SYSTEM SOL IFB 662-2-98 DUE 101697 POC Daryl Hanson, (415) 750-2172 The Vendor shall provide site assessment and planning, installation, training and continuing operational supervision for an Image Management System (IMS). The IMS shall permit capture, transmission, archiving, and display of medical images on diagnostic workstations. The IMS shall provide networking services as required to install Local Area Networks, Wide Area Networks, and Internet/Intranet, sufficiently robust to accomodate anticipated patient data loads. The system shall be open architecture, modular, scaleable, and use industry standards including DICOM 3.0, HL7, and TCP/IP. The Vendor shall provide film digitizer(s) capable of digitizing 200 images per hour with one FTE at a minimum resolution of 2K x 2.5K, and with at least 10 bit depth of grayscale. The digitzer shall be capable of preview. The vendor shall provide direct image capture for an existing ALI ultrasound system, two Siemens Vision MRI systems, one GE Cti Ct system, one Elcint nuclear medicine review station, and one Philips EasyVision review station. Sixteen bit bandwidth digital interface shall be provided to all modalities where applicable. The vendor shall be responsible for resolving all interface problems between the IMS and these systems. Where DICOM interface is not available on the modality equipment, the vendor shall provide a functionally equivalent digital interface. The vendor shall provide -- two single monitor 1K resolution radiologist review stations, five dual portrait monitor 1K resolution radiologists review stations, two dual portrait monitor 2K resolution radiologist review stations, two dual portrait monitor 2K resolution clinician review stations, and one four portrait monitor 2K resolution radiologist review stations. Single monitor systems shall be 17 inch diagonally, and capable of displaying 24 bit color. Dual monitors systems shall be 110 lumens or greater. Monitor shall be fliker-free (>70Hz). Viewable raster shall be no less than 18 inches, and no more than 25 inches diagonally. Monitor shall display the full spatial and contrast resolution that was delivered to the network, with a minimum 8 bit depth grayscale protocol. Workstations shall be minimally 586/686 Pentium-based or equivalent, with 96 MB RAM,L2 cache, 2 GB hard drive, 100baseT network interface. Required functions include: Two-way image communication with automated image routing. System for patient information security. Reading list. Image retrieval by exam number, patient name, patient ID number, modality, date, and/or study type. Image retrieval from the IMS or other medical systems on the WAN using DICOM query/retrieve protocol. Both real-time and pre-fetch image retrieval capabilities. User and modality-specific profiles for arrangement of images on screen, window and level settings. Ability to divide monitor into multiple regions,each with different studies or image series. Synchronous paging of different studies or image series. Tools to pan, zoom, cine, rotate, flip, window, level. Ability to display cine movies,such as Doppler ultrasound, coronary angiograpohy and heart wall motion studies, at 30 frames per second or greater. Ability to mark images as "read." Preliminary report annotation. Audio and graphical annotation, which follow image location. Flagging of key images. Provision for assigning images to teaching file. Printing of selected images. Decompression of images, if sent compressed. The vendor shall design and install a local area network with a minimum 100 megabits per second speed for communication between IMS devices. There are approximately nineteen nodes. WAN capabilities suited to T1, T3, ISDN, POTS, and line-of-sight bit rate wireless shall also be provided. The network operating system shall be Windows NT or functional equivalent. Topologies supported consist of star configuration on CAT5, fiber and wireless. The servers shall acquire images from clinical modalities and deliver them to diagnostic workstations. Servers shall coordinate all image archive and retrieval, data transmission, and inter-links to the DHCP, the Medical Center LAN, and with IMS systems at other Medical Centers. Server shall be DICOM service class, and shall suport queries for images both to and from the IMS of other medical centers, including that of the University of California San Francisco, and the Palo Alto VAMC. The vendor shall provide servers with capacity of six months (256 GB) primary RAID 5 storage, and two years (2TB) long term MOD storage. The RAID shall have hot swap capabilty. The MOD shall have at least 12 drive heads. Long term storage may be performed with lossless JPEG compression. The server shall have the ability to archive images from pathology, dermatology, endoscopy and other non-radiologic modalities. The vendor shall provide an interface to the DHCP hospital information system that will allow, at a minimum, downloading of radiology reports, patient demographics, patient loction, and study identification. Entry of images, by film digitization or by direct capture, shall require reconcilitation of name and patient identification with the DHCP database. All timings shall be made under loaded network conditions. The IMS shall be capable of routing image data by referring physician, radiologists, and patient location. Two newly acquired images from digitzer(s) at 2K by 2.5K resolution, or 50 images from MRI or CT, shall be made available at a diagnostic review station with 25 seconds after acquisition at the modality is concluded. RAID images -- The workstations shall display on demand a list of patient cases to be read. Once a patient case is selected at the workstation, the full frame of the first 2K x 2.5K images shall be displayed within one second of the requesting keystroke. Images from cache shall be virtually instant. Long-term archive images -- A set of 6 chest and 50 CT images shall be available in the workstation for display no longer than six minutes after initiating the request. The vendor shall be responsible for providing orientation and training of personnel in operation, care, and quality control of the equipment furnished. An ongoing training and retraining program shall be a component of the curriculum. The vendor shall provide a full time local representative with clinical and application credentials to continuously monitor system operations. This supervision shall include training, quality control, and project liaison with the vendor. Electronic support shall be incorporated for detection of out-of-tolerance situations. The vendor shall provide a maintenance agreement to support a 99.9% up-time. The vendor shall provide software within-version upgrades automatically and without charge. The vendor shall provide server(s) and software to allow viewing of images on existing Macintosh, Windows and UNIX computer systems by use of a web browser. The vendor shall provide the option of purchasing a site license to allow viewing of images on Pentium-based Windows NT VistA computers. The vendor shall the option of purchasing a system for home teleradiology. The vendor shall have installed an IMS with similar components and performance ina North American medical center. This sytem shall be available for a site inspection. General construction, including construction of air conditioned computer rooms and of communications closets, shall be outside the scope of this project. Construction required to install LAN, including running cables, installation of wall sockets, and necessary routers, hubs and switches, shall be within the scope of this project. Requests for solicitations must be made in writing. Contract award shall be made based on price and price-related factors adhereing to the specification listed above. (0254)
