Calculation of compound shape elements (rosette-like) on the blood preparation image

摘要

At present, most of the medical institutions of Russia use manual methods for the calculation of blood shape elements. Usually, a laboratory assistant conducts the calculation under the monocular microscope with imposed Goryaev's graticule. Goryaev's graticule consists of 256 large squares, divided into 16 small ones. The squares involvement in the calculation depends on the particles' type. For example, at the calculation of leukocytes 100 large squares are used and at the calculation of erythrocytes 80 small squares are used. The manual calculation is slow enough and toilsome, therefore the task of the elaboration of automated methods of particles' calculation appears. The elaborated methods are based on the same principle as is the case for the manual ones: the image in some number of squares of Goryaev's grid is input into a computer and then is processed. In this paper, the calculation of rosette-like shape elements is described.
