ABSTRACT:
A computerized specimen encoder for use with microscope analysis and pathological studies. The slide encoder is attached to the movable microscope stage, whereby X-Y plane movement and location, is correlated to examination of a specimen on an identified slide, with information marking and location being directly correspondingly written on computer storage media, during the examination. The information marking is in the form of computer generated indicia which are placed at a computer image location of the slide at predetermined time intervals. Subsequent use of the computer-stored information, coupled with the slide encoder, in a slide re-examination, permits independent retrieval of such information and location on the slide. The encoder device is provided with a grayscale marker which marks in varying shades of gray, ranging from white to black, the time spent by a slide screener on a particular portion of the specimen and the number of times spent viewing a particular portion of the specimen.
