Method for detecting the movement of a temporomandibular joint
Described is a method for detecting and displaying the movement of a temporomandibular joint which connects a lower jaw and an upper jaw by magnetic resonance imaging. A marker is secured to the lower jaw, a marker movement curve is generated using magnetic resonance imaging measurement data sets during a first measurement interval, during which the lower jaw is moved relative to the upper jaw, and a point which corresponds to a first position of the lower jaw relative to the upper jaw is ascertained on the movement curve. An image data set is generated during a second measurement interval, during which the temporomandibular joint is not moved, and a first model, which represents at least one part of the upper jaw and/or a temporal bone part that comprises the temporomandibular joint socket, and a second model, which represents at least one part of the lower jaw, are ascertained therefrom. A movement curve of the second model relative to the first model is calculated and displayed using the marker movement curve.
