The invention relates to a method for detecting and displaying the movement of a temporomandibular joint (4) which connects a lower jaw (2) and an upper jaw (5) by means of magnetic resonance imaging. A marker (1) is secured to the lower jaw (2), a marker movement curve (7) is generated using magnetic resonance imaging measurement data sets (6) during a first measurement interval (T1), during which the lower jaw (2) is moved relative to the upper jaw (5), and a point which corresponds to a first position (P1) of the lower jaw (4) relative to the upper jaw (5) is ascertained on the movement curve. An image data set (8) is generated during a second measurement interval (T2), during which the temporomandibular joint (4) is not moved, and a first model (50), 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 (20), which represents at least one part of the lower jaw, are ascertained therefrom. A movement curve of the second model (20, 20') relative to the first model (50) is calculated and displayed using the marker movement curve (7). |
