78. Converting EEG, ECG and other paper legated biomedical maps into digital signals

A na´ve and straightforward digital signal processing tool developed using Matlab is offered as a very low-cost and quite effective strategy for analog-to-digital conversion of signals without requiring dedicated hardware. This software-based approach is particularly helpful for digitalizing biomedical signals acquired from analog apparatus equipped with a plotter. Albeit signals used in biomedical diagnosis are the primarily concern, this imaging processing tool can be suitable and economically feasible for modernizing facilities in a non-expensive way. As an appealing feature, old ECG and EEG charts can be fast and efficiently digitalized in order to be added in existing up-to-date medical data banks of cardiologists and neurologists to improve the follow-up of patients.
