A head restraint device for medical imaging apparatus such as medical resonance imaging (MRI) apparatus is described. The device includes a base (2) including a support (8) for supporting the back of a subject s head. A first arm (4) and a second arm (6) are also provided the proximal ends of the first and second arms being attachable to the base (2) such that the distal ends (22, 36) of the first and second arms (4 6) are spaced apart from one another to form a region for receiving a subject s head. One or more head grips which may include bone pins (46) are provided that are attachable to the distal end (22, 36) of each of the first arm and second arm (4, 6) for engaging a head located in the region for receiving a subject s head. An arm positioning mechanism allows the spacing between the distal ends (22, 36) of the first and second arms (4, 6) to be altered such that the size of the region for receiving the subject s head can be adjusted. |
