A control section for controlling the operation of the flash tube includes a patient circuit, an intermediate circuit and a primary circuit. Optoisolators are provided to connect the intermediate circuit to the patient circuit as well as to the primary circuit while electrically isolating the intermediate circuit from the patient circuit and from the primary circuit.
