MKC-305A    
High Performance 3-chip CCD Camera for Microsurgical Application

The MKC-305A is a state-of-the-art, high-performance color camera, employing high-density CCDs to deliver unmatched image quality .Developed by Ikegami in its search for excellence in the field of medical imaging, the MKC-305A incorporates precision RGB prism optics and FIT (Frame Interline Transfer) CCDs with approximately 400,000 pixels in its image sensing device. These work together to yield superior color fidelity and image quality with enhanced sensitivity . Ikegami ' s sophisticated video technology has been fully utilized to reproduce true-to-reality scenes of the most advanced surgical procedures. The surgical microscope camera system, with the MKC-305A at its core, represents the optimum system configuration for microsurgery. Vivid color images captured by the MKC-305A during surgical procedures can be recorded on a VTR together with sound or documented with 35mm still photographs, while hard copies can also be printed out of the images being viewed used in conjunction with a color video printer. The MKC-305A will open up new opportunities for microsurgeons.

Features
  • High-Density CCD Pickup Device
  • High-quality image for clear-definition pictures
    The FIT CCDs, containing about 400,000 pixels, and the precision optics work in tandem to yield clear-definition images with 700 lines of horizontal resolution and a SIN ratio of 59dB or more.
  • High sensitivity
    The high-sensitivity AT CCDs ensure optimum performance with a standard sensitivity of 2,000 Ix at f8 and a minimum illumination of 15 Ix at fl.2. The high- performance CCDs solves the problem of low sensitivity enabling sharp, crisp images to be reproduced.
  • Simple maintenance and ease of operation
    The CCD image sensor substantially reduced complex, time-consuming adjustment and maintenance procedures and offers the following advantages: Freedom from streaking, ensuring a minimum of after-image. Excellent resistance to vibration and shock. Immunity from the effects of strong electrical or magnetic fields. A compact and lightweight structure, with low-power consumption.
  • Ikegami's Advanced Video Processing Techniques Achieve the Purest Image Possible
  • Image enhancer incorporating newly-developed
    ultra-compact supersonic delay lines The 2H-DTL and soft-DTL ensure sharp image enhancement with a superior S/N ratio.
  • Auto highlight compression circuit
    Even for highlight shooting, natural-looking images are assured with no" washed out" appearance.
  • Auto flare compensation circuit
    The amount of flare is automatically detected to deliver crisp images without any fogging or white noise.
  • Chroma aperture and RGB DTL-KNEE
    Image contours with white glare are softened to provide natural-looking images with superior color fidelity.
  • Versatile Functions with Emphasis on Operational Flexibility
  • Electronic shutter
    The MKC-305A incorporates a three-step electronic shutter with 1/100, 1/500, 1/1000 sec. to capture clear images.
  • A Design Philosophy Giving Full Consideration to Ease of Operation
  • Separate design
    The compact and lightweight camera head is designed as a separate unit from the CCU. This substantially improves ease of operation.
  • One-touch, water-resistant connector
    Tight-fitting one-touch connectors of water-resistant construction are employed for simplicity of operation and high dependability .
  • Slender camera cable
    The camera cable connecting the camera head with the CCU is made as thin as possible for maximum convenience. It is terminated with connectors on both ends to facilitate cable extension. The camera cable can be easily extended with a cable joint adaptor for tract mount and ceiling mount applications.
  • Optional Operation Functions
  • Characters and arrow pointer display
    Characters and on arrow pointer can be superimposed on the image being filmed, data related to the on-screen image can be referred to at all times. Up to 16 sets of character images can be stored. Images can also be recorded on a VTR or in hard copy form with the preset characters superimposed on them. This feature of recording images together with various data provides a useful tool for studying patient cases and surgical techniques. The following characters can be super- imposed on the image:
  • PATIENT'S NAME, NO.
  • AGE
  • M/F
  • DATE, TIME
  • DOCTOR'S NAME
  • HOSPITAL'S NAME
  • FREEZE COUNTER
  • ARROW POINTER
  • Freeze function
    Single frame images, can be frozen, providing the advantages of close observation of a particular image as well as a print out for hard copy documentation.
  • System Applications
  • Special microscope adaptor
    Two types of dedicated adaptors are available to enable the MKC- 305A to capture images of the scene being viewed through the surgical microscope. The CZA-1 is a single adaptor which provides an interface for observing images on the monitor or recording them on a VTR. The CZA- 7 is a dual direction adaptor for 35mm still photographs as well as for video monitoring and VTR recording. The MKC-305A optionally interfaces with the Carl Zeiss Superlux 300/301 Light Source in the photo pulse mode. This enables brighter and sharper still 35mm photographic images to be taken. Selecting the photo pulse mode on the CZA- 7 foot switch ensures the Carl Zeiss Superlux 300/301 Light Source flashes by synchronizing with the still camera shutter release.
