A method for determining the location, in a coordinate system, of a target position for an invasive medical procedure on a patient. An entry mark that defines the coordinate system and indicates an entry position for the procedure is affixed to the patient. A site marker, which can be identified in a radioscopy image, is fixed in a known relative location in the coordinate system. At least two 2D radioscopy images of the patient, which both depict the respective site marker and the target position, are recorded from different recording directions. The location of the target position in the coordinate system is determined from the representation of the target position and from the representation of the site marker in the 2D radioscopy images and from the relative location of the site marker in the coordinate system.

Method for determining a target position for a medical procedure

A patient support apparatus is provided. The patient support apparatus may be used as an operating table apparatus for a neurosurgical intervention. The patient support apparatus includes a support couch and a transfer plate which may be moved relative to the support couch, wherein the transfer plate is designed to support a patient for the neurosurgical intervention, wherein the patient support apparatus includes a holding unit with a support shell, which is designed to support a head of the patient and/or a surgical head restraint unit, and a fastening unit for fastening the holding unit to the patient support apparatus.

Patient support apparatus

A patient positioning table has a transfer plate that is reversibly transferable from the patient positioning table to a table associated with an imaging modality, and a headrest-forming extension component having a fastening section and a supporting section is provided, which can be detachably fastened to fastening devices provided on the transfer plate in exchange for a framework-like head immobilizing fixture, which can be detachably fastened to the same fastening devices.

Patient positioning table having a transfer plate

Disclosed is a patient support apparatus having a patient support couch, a moveable support plate for supporting a patient, a surgical head fastening unit for fastening a head of the patient in an examination position and/or in an operation position. The patient support apparatus includes a marker unit for marking a maximum occupancy area for the surgical head fastening unit.

Patient support apparatus, a medical imaging apparatus with the patient support apparatus and a method for marking a maximum occupancy area

A patient positioning apparatus is provided. The patient positioning apparatus includes a positioning table, a transfer plate, which is arranged on the positioning table so as to be moveable relative to the positioning table, and a positioning unit for a positioning of a surgical head securing unit on the transfer plate, wherein the positioning unit exhibits a joint unit with at least one first rotational joint unit, wherein the at least one first rotational joint unit exhibits a predetermined stop position for a rotational movement.

Patient positioning apparatus and a medical imaging apparatus comprising the patient positioning apparatus

In a method and medical imaging system to prepare an interventional and/or diagnostic imaging procedure to be conducted with at least two different medical imaging modalities of the system, a patient is positioned on a patient support device and the patient support device, together with the patient, are moved into a patient acquisition region of a first medical imaging modality of the system. A first image data set of the patient to be examined is acquired with the first medical imaging modality. The first image data set is automatically evaluated in a data evaluation unit. At least patient parameter is automatically calculated from the evaluated first image data set. At least one compatibility value is automatically calculated depending on the at least one patient parameter and depending on at least one apparatus parameter of at least one additional medical imaging modality in the system. The compatibility value indicates whether the additional modality is compatible with the patient in order to conduct another of the procedures using that additional modality.

A patient support apparatus having a support table, a transfer plate, which is disposed movably in relation to the support table in a direction and on which a patient is supported for a surgical intervention and/or a medical imaging examination, and a surgical head restraint unit, which is disposed on the transfer plate is provided. The patient support apparatus includes a position monitoring apparatus for monitoring and/or checking a position of the surgical head restraint unit.

Patient support apparatus and also a positioning method for positioning a patient's head within a surgical head restraint unit

The device enables the detection of positions of the navigation marking elements on a reference star by way of at least two projection images taken by an X-ray system at different pivoting angles of a C-arm. The positions of the navigation marking elements on the reference star are also calculated by a navigation system tracking camera. The transformation from the coordinate system of the navigation system into the coordinate system of the X-ray system is calculated from the position of the reference star detected by the X-ray system and the position of the reference star detected by the tracking camera. The navigation marking elements are located outside of the volume which is reconstructed by way of the imaging process in order to prepare tomographic images. The positions of the navigation marking elements are determined from two-dimensional projections. All the navigation marking elements need only be detected by at least two projection images.

Determining and verifying the coordinate transformation between an X-ray system and a surgery navigation system

A patient support apparatus is provided. The patient support apparatus has a patient table, a movable support plate for supporting a patient, a guide unit, which is designed to guide the support plate along at least one movement direction of the support plate, and a fastening unit for fastening an auxiliary unit to the support plate. The fastening unit has at least one setting unit for setting the position of the auxiliary unit in relation to the support plate in a flexible manner.

Patient support apparatus and medical imaging apparatus having the patient support apparatus

A patient support apparatus, in particular for a medical imaging apparatus, has a table for supporting a patient, and a support unit, wherein the table is arranged at the support unit such that the table may be displaced along a longitudinal extension of the support unit. Further, the patient support apparatus has a protective wall element which closes off a region for receiving fluids on the table and/or on the support unit in a fluid-tight manner.

Patient support apparatus and medical imaging apparatus comprising the patient support apparatus

A device and method are provided that enable calibration information to be determined for an x-ray apparatus that performs a three-dimensional x-ray scan. The calibration information is determined using an adapting method, wherein the adapting method is based on a position of an x-ray source relative to an x-ray unit marker device during image acquisition, an x-ray unit data set that describes the position of the x-ray unit marker device during image acquisition, and a two-dimensional calibration data set that describes at least one and preferably two actual two-dimensional x-ray images produced by irradiating a calibration object.
