A method for producing a pacifier teat, and a pacifier teat with a teat section which forms a hollow space and which is adjoined by a stem, wherein an elastic hollow body comprising the teat section and the stem is injection moulded or pre-formed by a dipping method, and opposite wall sections of the pre-formed hollow body are connected to each other in the region of the stem. According to one embodiment, among many, a computer readable medium is configured to store instructions that are executable by a processing device. The radiopaque member is composed of a metallic material capable of forming an X-ray image and arranged outside the wire body and in the lengthwise direction of the wire body. The extractor may also include a module that compensates for a misaligned scanned input by automatically detecting the rotation and translation, and then registering the image so that the upper-left corner is located in a certain position.
