1. An x-ray recording system, comprising: an x-ray emitter for generating a beam used for imaging; an imaging x-ray detector with a two-dimensional or three-dimensional recording geometry for determining an attenuation of rays of the beam; a patient bearing and/or positioning device for a patient, in a recording region of the x-ray recording system between said x-ray emitter and said x-ray detector; at least one time-of-flight (TOF) camera for establishing a contour of the patient; and a computer unit with a memory and software stored in said memory, said computer unit embodied, during operation, to generate a three-dimensional wire model of the patient with joint locations disposed therein from the contour of the patient recorded by said TOF camera and to simulate and display at least one anatomical structure scaled to the three-dimensional wire model.
