Abstract: The invention relates to a fixation system for attaching a medical image registration matrix (40) to a patient holder (2) which is to be covered by a sterile drape (10), wherein the fixation system comprises at least one fixation set (L, R) comprising a lower part (6) which is adapted to be connected to the patient holder (2) and an upper part (26) which is adapted to be connected to the registration matrix (40) or one of its supporting elements, wherein: the lower and upper parts (6, 26) can be connected to each other by a connector (25) which does not penetrate the drape (10); the lower and upper parts (6, 26) comprise mutually engageable profiled interfaces (8, 28) which are formed so as to accommodate and clamp the drape (10) between them; and wherein the profiled interfaces (8, 28) fit together over a continuous zone of engagement.

Abstract: A connector for attaching a reference array in a fixed positional relationship with respect to a patient to be covered by a sterile drape in an attachment area, includes a support to be situated below the drape and a clamping element which is to be situated above the drape and can directly or indirectly hold the reference array or a reference array adaptor, wherein the clamping element clamps the support, with the drape caught between the two, by at least two distinct clamps which clamp the support from at least partly opposing directions in such a way that the positional shift in the clamping element as a result of clamping the drape at the clamping position is compensated for, such that its overall positional shift is substantially zero. A method attaching a reference array in a fixed positional relationship relative to a patient above a sterile drape is also provided.
