    Hello,

    I am using our Citoviva system equipped with a digital CCD camera (Retiga 4000R, QImaging). All the images we capture with this camera present a strange structure (with of squares) in the same region of pixels of all images. This can be observed in the image I am attaching.
    Do you have idea of what can it be? A defect in the camera?

    Thanks in advance!
    Alex

      Alex,
      This is indeed strange! Did this just start? Is the pattern always in the same place on the chip/image?
      I will send this to Qimaging and see what they think.
      Thank You!
      Jamie

      Hello,

      Thanks for the answer!

      It started one or two months after the system installation.
      An additional information: the pattern is always in the same palace, even when we rotate the camera. Maybe this is not a problem with the CCD.

      Regards,
      Alex

        Alex,
        Does it only really show up when the image background is bright?
        There may be an IR filter you need to resolve this pattern. Elyse from our office will e-mail you with details.
        Thanks!

        Hello Jamie,

        Do you have any new information about this subject?

        I am not yet contacted by the your office.

        I checked, and the pattern also appears in the darkfiled images, as you can see in the image I am attaching.

        Regards,
        Alexandre
