A body part positioning table or table overlay includes a planar surface to support a body part. The table or table overlay further includes a first mask mounting system having a first configuration for mounting a first mask that positions and secures the body part relative to the planar surface, and a second mask mounting system having a second configuration for mounting a second mask to position and secure the body part relative to the planar surface.

The disclosure relates to an apparatus and to a method for fixing a target object in place and for orienting an instrument relative to the target object which has been fixed in place. The target object is here fixed in place by a first mask element. A second mask element is arranged on the outside thereof. By an adjusting facility, the second mask element may then be shifted relative to the first mask element, whereby the instrument retained by or passed through the second mask element is oriented.

The invention relates to a device for immobilizing the head of a patient in an installation for carrying out radiotherapy, wherein the device comprises a thermoplastic mask, shaped according to the contour of the patient's head, and a mouthpiece, wherein the mouthpiece has a central part from which a spout protrudes in the direction of the mouth and from which a holding structure protrudes in the direction away from the mouth, wherein an air channel is provided which extends through the mouthpiece from the mouth-side end of the spout to the side of the central part in the direction away from the mouth, and wherein a region of the mask is shaped according to the contour of the holding structure. The invention further relates to a method for producing such a device, to the use of such a device for immobilizing the head of a patient in an installation for carrying out radiotherapy, and to an installation for carrying out radiotherapy which, in order to immobilize the head of a patient, comprises such a device.

Various cranial surgery OSS registration device embodiments of the present disclosure encompass a cranial surgery facial mask (128), a mask optical shape sensor (126b) having a mask registration shape extending internally within the cranial surgery facial mask (128) and/or externally traversing the cranial surgery facial mask (128), a cranial surgery tool (101), and a tool optical shape sensor (126d) having a tool registration shape extending internally within the cranial surgery tool (101) and/or externally traversing the cranial surgery tool (101). The mask registration shape of the mask optical shape sensor (126b) and the tool registration shape of the tool optical shape sensor (126d) interactively define a spatial registration of the cranial surgery facial mask (128) and the cranial surgery facial mask (128) and the cranial surgery tool (101) to a cranial image.

Systems and methods are described for the monitoring of patient motion via the detection of changes in capacitance, as measured using a capacitance position sensing electrode array. The changes in capacitance may be processed to determine a corresponding positional offset, for example, using a calibration data set relating capacitance to offset for each electrode of the array. The detected positional offset may be employed to provide feedback to a surgeon or operator of a medical device, or directly to the medical device for the control thereof. A medical procedure may be interrupted when the positional offset is detected to exceed a threshold. Alternatively, the detected positional offset may be employed to manually or automatically reconfigure a medical device to compensate for the detected change in position. Various configurations of capacitive position sensing devices are disclosed, including embodiment in incorporating capacitive sensing electrodes with a mask or other support structure.
