DIVA DIGITAL IMAGING SYSTEM

Our computer-based DIVA Digital Imaging System is the basic building block for all current and future products. This system includes a computer-based camera system that captures camera images from within the body cavity and displays them on a surgical monitor. The computer directly interfaces our DirectView™ and TheraScope™ endoscopes with a remote camera, which, in turn, connects to HDTV grade video monitors. This DIVA Digital Imaging System offers equal or greater image quality than that of existing camera systems, but at a fraction of the cost, and can be used with all current endoscopes, light sources and video monitors. In addition, the computer-based digital camera and video monitor provides other features beyond imaging for convenience and ease of use.

The camera system interfaces directly with our laparoscope, with or without the use of an endo coupler, and functions in the usual manner to interface with conventional endoscopes as well. The camera is operationally transparent with any endoscopes that use software for electronic zoom and automatic brightness control. Pushbuttons enable user functions and set-up for a given application for more interactive input, a keyboard, mouse, or flash memory can be used. The flash memory offers a convenient method to retain patient information and selected images from surgical or diagnostic procedures. VHS and CD media are also available for image and data storage.

In addition to matching features that are now available on most camera systems, MITI’s camera panel layout will include input/output capabilities: flash memory, internet access, high speed sequencing, and hardware and software safety systems.

The DIVA Digital Imaging System is compatible with all video monitor formats including NTSC, PAL, VGA, DVI and HDTV. Future therapeutic capability will be built into all our imaging systems to permit photo microbial, photo fluorescence, photo dynamic and laser therapy when activated. This additional capability works in tandem with our DIVA Multispectral Pulsed Light Source to perform light therapy. As the DIVA Imaging System is computer-based, it comes with internet access via USB or LAN format I/O. Provisions are also made to monitor and display up to 30 channels of discrete data from other operating room sensors.

The DIVA Digital Imaging System works in a dynamic or “pulsed” mode using our Multispectral Pulsed Light Source with therapeutic light capability as well as with all DC conventional light sources and endoscopes. However, its camera and software systems are specifically designed for therapeutic multiplexing capability. In contrast, conventional endoscopes work only with DC light sources that provide continuous light output.

Time Domain Multiplexing is the process of managing the time continuum during each camera’s acquisition cycle. The cycle is initiated by a camera command, followed by an image acquisition cycle. In turn, this is followed by commands to a monitor to process and display the captured image. If no intervention is commanded, the time to the next pulse is “Dark Space.” Should therapeutic laser, photo microbial or photo fluorescent or other therapeutic command be requested, these functions are initiated and controlled by the computer during a “Dark Space” interval.
