Abstract: A spark gap comprising a cathode and an anode is provided. The spark gap is divided into two partial spark gaps by means of a central piece, namely a high-pressure spark gap and an effective spark gap. The effective spark gap can for example, be used to generate monochromatic x-rays. In order to guarantee a defined switching time, the high pressure spark gap which is initially switched to defined, is used. The switching initiates a potential so high on the centre piece that, when the high pressure spark gap is switched, the effective spark gap can also be switched in a defined manner without significant delays, to a visibly higher voltage.

Abstract: In a method for generating a tomographic image, at a first point in time, a first tomographic image is acquired of a layer of a patient and the region of cartilaginous tissue is determined in the first tomographic image. At a later second point in time a second tomographic image is acquired of the layer of the patient and the region of the cartilaginous tissue is determined in the second tomographic image. The tomographic image is generated from the first tomographic image and the second tomographic image, in which every pixel of the tomographic image is assigned a difference value between a corresponding pixel of the first tomographic image and a corresponding pixel of the second tomographic image. The validation number is determined by adding all the pixels in the region of the cartilaginous tissue in the tomographic image.
