[Machine based chromosomes investigations with the Quantimet 720 (author's transl)].

Abstract

A system is described, looking in a short time and automatically for metaphases qualified for further usings. Scanning time for 1 cm2 is about 8 minutes. The accepted metaphases are relocatable immediately. Chromosomes are classified in a further routine using chromosome area and area ratio of the chromosome arms. The characters are displayed on the screen near the single chromosomes. Furthermore there is the possibility to measure the banding of whole chromosomes or of single chromatides and display it in form of histograms on the screen.
