Abstract
A system is disclosed for generating a maturity index for blood cells which may be used in a hematology profile to show the health of a patient. The system includes a scanning system for scanning a cell, pattern recognition means connected to the scanning means for generating a plurality of groups of signals, each group representative of a different characteristic of the cell scanned, and calculation means responsive to the signals for calculating an index of maturity for the cell scanned in accordance with its characteristics.
Claims7
A pattern recognition system having apparatus for generating an index of a cell's maturity, including a scanning system for scanning a cell, pattern recognition means connected to said scanning means for generating a plurality of groups of signals, each group representative of a different characteristic of the cell scanned, and calculation means responsive to said signals for calculating a cell maturity index for the cell scanned in accordance with its characteristics, said calculation means including means for assigning a different weight to different ones of said characteristics to generate signals representative of said characteristics in accordance with their relation to the cell's maturity and means for combining said characteristic signals so that a weighted average is calculated which is representative of the position of the cell in the continuous range from immature to mature cell.
A pattern recognition system having apparatus for determining a disease state including means for scanning blood cells in a whole blood smear, means responsive to said scanning means for producing signals representative of a plurality of characteristics of a particular type of blood cell, calculation means responsive to said signals for generating a maturity index representative of the position of the cell in the continuous range from immature to mature cell and storage means for storing the maturity index of each blood cell of said particular type in said whole blood smear and display means for providing a graphic display of the number of cells at a plurality of index ranges within the entire range from immature cell to mature cell.
