Hospital da Luz - Project Description
This project was drawn in order to create an effective solution for the visualization of medical acts in real time. The auditorium is connected to three operating rooms, to the CPRE room, and the two gastroenterology rooms. Broadly speaking, this system allows the people present in the Auditorium to follow the medical acts practiced in the several rooms afore mentioned in real time.
This interconnection allows the physician who is performing the event to communicate both with the participants in the Auditorium and in the other rooms, and to broadcast it to any external receptor. Thus, this project will enhance the observation and training of medical acts to a wider audience. For example, we can have an operation taking place in Lisbon and being watched in any other part of the world. It is also possible to send and receive graphic images such as "medical examinations" The auditorium has the following functionalities: - Large-screen playback possibilities of video conference signals, resolutions of 4000 x 2000 pixels or 1024 x 768 pixels; - Possibility of capturing, mixing, recording and broadcasting video and audio signals in DVD format, - Large-screen broadcasting possibilities of PC, DVD and HDV signal sources, - Integrated control of the entire audiovisual system through the control panel; - Possibility of intercommunication and transmission of images of the Auditorium for each operating room. Description of each room’s operation When a transmission of a medical act to the Auditorium is scheduled, the connection with said room is initiated from the Auditorium. This intercommunication is private and will not be heard in the Auditorium. In addition to the intercommunication, the physician's microphone / headphone system will also act in the diffusion in the Auditorium of the physician’s explanation about the ongoing surgical intervention. It will also make possible to listen to any questions asked by the assistance. Each room has 2 monitors. The physician can select the local image of the surgical light, or the rotating chamber on one of the monitors, or receive the remote image from the Auditorium. The second monitor may receive the local graphic image of a PC, or of a local high resolution source, of a graphic image from the Auditorium, and a graphic remote image coming from the videoconference system. The selection of signal sources of the monitors is controlled locally through a system of pedals to spare the use of the doctor's hands. The control of camera’s movements, given its complexity, will be done remotely through the touch panel in the Auditorium. Each pedal used by the Doctor will have a specific function. A pedal selects alternately the images you want to see on the video monitor (rotating camera, surgical light camera, or image from the Auditorium). Another pedal controls the image selection of the second monitor. This monitor may reproduce the high resolution local source image or the image from the Auditorium. A third pedal will allow the selection of the video signal source to be transmitted to the auditorium, rotating chamber or surgical light, and finally a fourth pedal that will raise or lower the room audio level. The controller with software developed for this specific situation receives the information coming from the pedal systems of the touch panels in order to control the video cameras. This controller is connected to the Auditorium controller by a TCP / IP network to allow the reception and sending of commands from the Auditorium to the rooms and vice versa. Auditorium The auditorium is composed of a high-resolution projector so that it is possible to watch the images from the operative blocks with the maximum quality, since the visualization of an operation requires full attention to the details, and these must be entirely reproduced. A LCD monitor is placed on the ceiling facing the administration desk, to be used in videoconference situations with external entities, or videoconference with the operating theater. This monitor allows participants at the administration desk to visualize the remote video image coming either from the operating blocks or from outside via the video conferencing codec. Associated with this monitor there is a video camera that will have the function of capturing images of the participants of the administration desk. Participants will always be able to watch both the images being played at any given time on the LCD monitor on the ceiling, and the images from the monitors that are embedded in the chairperson’s desk. The Auditorium's control system commands all the existing devices, the lighting, the blinds, and is composed of two tactile panels, one is placed in the control room, and the other is placed on the administration desk. The Auditorium has four different configuration possibilities. - Isolated; - externally connected through the videoconference system; - Inter-connected to the operating theatre; - Simultaneously connected with operating theatre and externally.
