A device is disclosed for calibrating a magnetic resonance apparatus having a PET function. In at least one embodiment, the device includes at least one marker that is visible through magnetic resonance imaging and fixed with reference to the device; at least one holder, fixed with reference to the marker, for a receptacle for holding a PET tracer generating a PET signal during PET imaging; and at least one receptacle for holding a PET tracer.

A method for handling an information item (10) which originates from an information provider, is made available by a service provider and can be called via a communications network (5). The service provider allocates to the information provider an ident code (15) which identifies the information item (10). If the information provider does not sign on at the service provider within a specific time period by transmitting the ident code (15), preferably together with a handling instruction (20, 30, 40) relating to the information item (10), the service provider deletes the information item (10).
摘要:
A method is disclosed for determining the position and orientation of an endoscopy capsule guided through an examination object by using a navigating magnetic field generated by way of a navigation device. In the method, an X-ray machine is used to record radiation images in which the endoscopy capsule is shown. Further, the position and orientation of the endoscopy capsule are determined with the aid of the position-dependent and orientation-dependent image of the endoscopy capsule in the radiation images.
摘要:
A magnetic resonance apparatus has a transmission and reception coil system and a gradient coil system that is designed to generate a gradient field that is periodic in one spatial direction. The gradient field and/or the examination subject can be displaced in the spatial direction of the periodicity to generate a relative position change between the periodic gradient field and an examination subject, and the transmission and reception coil system comprises individually-activatable coil arrays to allow data to be acquired to fill in gaps or resolve ambiguous data entries that occur due to the gradient field being periodic.

In order, despite a plurality of terminals to enable their freedom of movement on the one hand and an unimpeded treatment process on the other hand to be guaranteed, there is provision in accordance with the invention, for recording the devices in their envisaged spatial distribution, especially by at least one camera to check this distribution as regards a sufficient freedom of movement of the devices especially by a processing or control unit and to feed back a corrected distribution, especially by at least one video projector.

An implantable fluid valve for the adjustable limitation of the fluid pressure in the brain of a patient, has all valve component parts composed of non-magnetic material, thereby making the valve MR-compatible.
摘要:
In a method for representation of medical image information on a display medium an image representation parameter is varied dependent on the position of the observer. Superimpositions of data sets from different medical examinations are thereby displayed. The observer thus has simultaneous access to information from the medical examinations, which makes the diagnosis easier for him or her.
摘要:
A device is for introducing a stent into a hollow organ, in particular into the gastrointestinal tract of the body of a patient. The device includes a magnet system which covers the area of treatment of the patient and generates a 3D gradient field for remote-controlled movement and orientation of an endorobot. The endorobot is provided with a linear magnet and is freely movable in the hollow organ. Further, the stent, which can be uncoupled from the outside, is secured to the endorobot in a folded-down state so that it can be brought to the site of use and can there be opened out so as to bear firmly on the wall of the hollow organ.
摘要:
A method is proposed for monitoring participation of a patient in at least one clinical trial. The method includes collecting data regarding at least one clinical trial for the patient. Using a computer device, the collected data is then compared to at least one threshold. Finally, the patient is rewarded upon the collected data at least meeting at least one threshold.
摘要:
A magnetic resonance apparatus disposed in an installation space has a first component group, which contain at least a basic field magnet system and a gradient coil system, a second component group, which contains an examination volume for receiving an object under investigation and which has at least one supporting device for bringing the object under investigation supported thereon into the examination volume, and sound insulation arranged between the first and second component groups so that the installation space is divided into two spaces which are sound-insulated from each other, a first of the spaces containing the first component group and a second of the spaces containing the second component group.
