With the invention a modular system for the mounting of shaft prostheses is shown which have a coupling which can be fixed within a predetermined angular range between the prosthesis stem and the prosthesis head, which can be fixed by an apparatus in the prosthesis stem. Through a modular system with combinable stems and prosthesis heads of differing sizes for prostheses and test prostheses which are constructionally alike externally and in the position of the point of rotation, a variety of test prostheses and shaft prostheses arises. The test prostheses have an apparatus in the prosthesis head which permit the fixing of the head in an ideal position with a controllable function in a stem inserted in a bone. This position between the head and the stem is preserved when the test prosthesis is extracted and transferred to a mounting apparatus, in which a shaft prosthesis which is built up of analogous parts is brought into the same position and fixed.

A head frame is configured for the head of a medical patient (108) and includes support for a probe and a neck support. The frame wraps around said head, and can be used in the supine position. The support may include a probe holder (116) slidable under the head and to contact or engage the neck support. In some embodiments, conformal shaping to the head and/or neck, the frame's rigid construction, the alignment of the optionally separable holder to the neck support (110), and weight of the head all serve to keep the distal tip of the ultrasound probe in place against the temporal region of the head, without need for attaching the frame to the head as by straps, providing an arrangement robust against patient/vehicle movement in an emergency medical services setting. Head immobilizing walls may be folded away (316) in some versions, retaining probe alignment. In the holder, an optional circular opening with a spherical cross-section allows the probe(s) to be rotated into position, and X-Y-Z positioning too may be provided, all manually or by motor.
