1. Apparatus for examining a tissue region for the presence of predefined target cells therein, comprisinga voltage pulse source;

  • an optical pulse source;

    a probe having an operative end for applying optical pulses and voltage pulses from said sources to the examined tissue region, and for detecting the reflections of said voltage pulses;

    and a data processor system including an electrical measuring sub-system coupled to said probe for detecting the reflections of said voltage pulses, said reflections indicative of changes in electrical properties of said examined tissue region produced by at least one of said optical and voltage pulses, and for determining therefrom the extent of the presence of said target cells in the examined tissue region;

    the voltage pulses and optical pulses being applied concurrently.
