Patient support device for an x-ray device and method for adjusting a patient couch of a patient support device

A patient support device for an x-ray device for use during an examination of a patient, the patient support device comprising:

• a patient couch comprising a first x-ray-transparent material disposed in an at least partially flexible covering made from a second x-ray-transparent material;
• and
• at least one support bearing the patient couch;
• wherein the first x-ray-transparent material includes a solid, dimensionally stable state and a deformable state that are linked by reversible phase transitions;
• wherein the patient support device further comprises at least one induction device configured to induce at least one of the reversible phase transitions of the first x-ray-transparent material between the states by applying, removing, or applying and removing energy;
• wherein the at least one induction device is configured to induce a phase transition to the deformable state to mold the patient couch in a desired form and then induce a second phase transition into the solid, dimensionally stable state, to allow the patient couch to solidify in the desired form.
