Abstract

The early stages of gastric cancer are not recognized due to its asymptomatic development. Detection of patho- logical changes can be achieved using the photodynamic diagnostics, but this approach provides rather low tumor selectivity. Additional opportunities to improve the detection of precancerous stages may be provided by ana- lyzing blood circulation in the vessels of the stomach. We consider the possibilities of multiresolution analysis in recognizing changes in blood circulation in rats with different levels of the fluorescent signal in the stomach associated with precancerous stages.
