Abstract:
In a method or system for limiting use of capsule endoscopes by a capsule endoscope maagnetic steering system used by a customer, the capsule endoscope is provided with a use code stored with the capsule. The use code is read and analyzed to determine whether or not the customer's capsule endoscope magnetic steering system will be enabled or disabled for use with the capsule endoscope from which the use code was read.
Abstract:
In a method for positioning a magnetically navigable endoscopy capsule using a magnetic coil system, to bring the capsule to a known finding position within a region in the body of a patient supported on a patient table, the finding position is identified in at least one volume data set that encompasses the finding position, the volume data set is registered with respect to the patient, the volume data set and the finding position therein are transformed into the coordinate system of the magnetic coil system, and the magnetic coil system is operated to position the endoscopy capsule inserted into the patient to automatically control routing of the capsule to the finding position.
Abstract:
A medical system has an electromagnetic navigation system and a patient bed that supports a patient during a medical procedure assisted by the navigation system. The navigation system includes at least one field coil that is integrated in the patient bed at a defined position.
Abstract:
In an imaging acquisition system and method, successive x-ray images and successive optical images are respectively acquired from an examination subject. Positional identifiers associated with the examination subject are detected in the optical images, and acquisition of respective x-ray images is triggered only when the identifiers are detected in the optical images. The number of acquired x-ray images is therefore substantially fewer than the number of acquired optical images, and the x-ray images can be acquired with substantially no overlap, thereby avoiding exposing the examination subject to unnecessary radiation.
Abstract:
An X-ray recording device has an X-ray detector and an X-ray emitter aligned with one another on a mobile supporting device, the supporting device being supported by retainer on a stand unit and being displaceable along a horizontal translation axis and/or vertical translation axis. The retainer has only one first pivoting arm rotatably mounted on the stand unit for rotation around a first vertical rotational axis and only one second pivoting arm rotatably mounted on the first pivoting arm for rotation around a second vertical rotational axis. This X-ray recording device allows an alteration to the recording range to be undertaken at reduced cost and with a space-saving and stable configuration.

Abstract:
An x-ray acquisition apparatus has a spatially adjustable x-ray detector, a spatially adjustable x-ray source, and a control unit with which the x-ray source can be aligned relative to the x-ray detector. The control unit accounts for the position of radio-opaque objects in the examination room and, before an x-ray acquisition, outputs a signal is a radio-opaque object is located in the beam path of the x-ray source.
Abstract:
In a method for directing X-rays radiated by an X-ray emitter onto a detector area of a X-ray detector, a location and/or positioning of the X-ray emitter and a location and/or positioning of the detector area of the X-ray detector is/are registered by a position registering device, with the location and/or positioning of the X-ray emitter and/or the location and/or positioning of the detector area of the X-ray detector being adjusted using the registered location and/or positioning of the X-ray emitter and the registered location and/or positioning of the detector area of the X-ray detector such that the X-rays radiated by the X-ray emitter will for the most part strike the entire detector area of the X-ray detector.
Abstract:
A medical apparatus has a data processing device for storing an image dataset of the body of a subject and a navigation system for determining the position of a medical instrument relative to the body of the subject. At least one bone fragment is shown in the image represented by the image dataset, the image of the one bone fragment being segmented with a computer. The bone fragment is to be grasped and set with the medical instrument. The data processing device also determines the modified position of the bone fragment on the basis of the position of the medical instrument relative to the body of the subject determined with the navigation system, and displays the modified position in the image.
Abstract:
In a system and method for determination of in-vivo orientation positions of an endoscopy capsule in the context of cable-free endoscopy, a magnetic field generator generates an electromagnetic HF-3D gradient field in the examining region, an endoscopy capsule has an integrated detector that ascertains the current respective position-specific and orientation-specific HF-3D gradient field values of the endoscopy capsule, a navigation unit is supplied with those values and assigns spatial information to the current HF-3D gradient field values, and a visualization unit displays the anatomical images acquired in a defined endoscopy capsule position and orientation on a monitor.
