Original Abstract

An improved technique for recording of contrac-tion of heart cells simultaneously with recording of calcium transients by fluorescence method is introduced. The tech-nique aims to quantify contractions under conditions including low image quality caused by reduced transmitted light. The proposed methods allow more accurate detection, lower error rate using the up-to-date image processing, and automation of the process comparing to recent approaches. The technique is compared with direct optical measurement method using processing of two-dimensional digital images of the cardiac cell. The technique is improved to be fast enough to be includ-ed in the system for real-time measurements.
