This invention relates to a non-invasive patient immobilisation assembly for immobilising a body part of a patient and for at least temporarily fixing the position thereof. The immobilisation assembly comprises a rigid template (1) made of a thermoplastic material. The template is thermoformed or otherwise moulded in such a way that the inner surface conforms to and contacts the body part to be immobilised along a contact surface area between the template and the body part. The contact surface area corresponds to at least part of the inner surface of the template. The immobilisation assembly also comprises a fixation plate (3, 12, 13) and connecting means (10, 11, 14, 15, 16) for connecting the template (1) to the fixation plate (3, 12, 13) in view of fixing the position of the template and the body part with respect to the fixation plate. The template (1) is provided to exert a fixation force of a preset value to the body part covered by it along the contact surface area by exerting a pulling force pulling the body part towards the fixation plate (3, 12, 13) with the aim of restraining the displacement of the body part within the template within defined limits. The assembly further comprises means (5, 6, 7, 17, 18) for adjusting the fixation force exerted by the template to the preset value.
