A displacement mechanism for placing an optical device onto a patient's eyes and removing the optical device from the patient's eyes when the patient is located in a patient bore of a medical imaging system. The mechanism includes a pneumatic device and a resilient element attached between an inner surface of the patient bore and the optical device wherein the resilient element extends through the pneumatic device and wherein the optical device is spaced apart from the patient's eyes in a first position. A pump inflates the pneumatic device to move the optical device to a second position wherein the optical device is placed on the patient's eyes. Inflation of the pneumatic device extends the resilient element and biases the resilient element to return to the first position. A vent valve vents air from the pneumatic device to return the optical device to the first position.

The presence or absence of objects tagged with transponders may be determined in an environment in which medical procedures are performed via an interrogation and detection system which includes a controller and a plurality of antennas positioned along a patient support structure. The antennas may be positioned along an operating table, bed, mattress or pad, sheet, or may be positioned on a drape, or shade. Respective antennas may successively be activated to transmit interrogation signals. Multiple antennas may be monitored for responses from transponders to the interrogation signals. For example, all antennas other than the antenna that transmitted the most recent interrogation signal may be monitored. Antennas may be responsive to force, a signal indicative of such force being produced. A wireless physiological condition monitor may detect patient physiological conditions and wirelessly transmit signals indicative of such.

A system includes acquisition of a first three-dimensional image of a patient volume using a magnetic resonance imaging scanner, acquisition of a second three-dimensional image of the patient volume using cone beam radiation emitted by the linear accelerator, and generation of a radiation treatment plan based on the first image and the second image.

Realized is a pedal mechanism that does not lock and does not provide an operation feeling unless operated in a determined order. The pedal mechanism has first and second pedals 105 and 106, first and second plates 108 and 109, and a locking bar 115. The radius of the second plate 109 is smaller than that of the first plate 108, and the second plate does not come into contact with the locking bar in a state where a circular-arc region of the first plate supports the locking bar 115. Therefore, the second pedal does not give an operation feeling even when stepped on, and the second plate cannot be locked. In a locked state where the locking bar is located in a cutout region of the first plate, the locking bar contacts the second plate, the second pedal provides an operation feeling, and the second plate can be locked.

A local coil for an MRI imaging system includes an antenna containing a first detuning circuit and a second detuning circuit, and a connection connected to the antenna between a first connection point on the antenna and a second connection point on the antenna. The connection is configured to be short-circuited by at least one diode. The first connection point and the second connection point are situated spatially between a first partial region and a second partial region of the antenna.

The invention relates to a device for contact-free control of a patient table includes a camera system for detecting at least one gesture of a user of the device, a processing unit for converting the at least one detected gesture into at least one command for controlling the patient table, and an execution unit for executing the at least one command for controlling the patient table. The device can furthermore include a monitoring system for monitoring the control of the patient table and an authentication system for authenticating the user.

The present invention relates to a patient support. In order to improve safety for MRI scanning protocols, a patient support is provided for an MRI scanner. The patient support comprises a braking device for deaccelerating the patient support when being transferred relative to the MRI scanner. The braking device comprises at least one non-magnetic electrically conductive element. The at least one non-magnetic electrically conductive element is configured to adjust one or more eddy currents induced in response to motion in a magnetic field of the MRI scanner to provide a counter force against an attractive force between the patient support and the MRI scanner, thereby creating an adjustable braking effect.

A method for performing an examination includes at least one magnetic resonance-based and at least one further examination step. An examination object is positioned during the entire examination on an upper side of a transfer plate that is positioned on an object table during the magnetic resonance-based examination. At least one coil holder that includes at least one local coil or by which at least one coil device is supported is used during the magnetic resonance-based examination step. The coil holder is arranged on the examination object during the magnetic resonance-based examination step exclusively. The coil holder is supported during the magnetic resonance-based examination steps by at least one mounting, into which a supporting section of the coil holder engages and/or which engages into the supporting section of the coil holder.

A patient couch is disclosed. In an embodiment, the patient couch includes a docking facility for mechanical docking on a docking point of a medical imaging installation; a drive unit including a plurality of wheels for a drive movement of the patient couch up to a docking position, where the docking facility reaches the docking point; at least one sensor, to acquire sensor signals characterizing a relative position between the medical imaging installation and the patient couch; a computing unit to calculate a movement trajectory with a destination of the docking position for the patient couch, based on the sensor signals acquired; and a display facility, to display the movement trajectory calculated for a user.

In a method and magnetic resonance apparatus for acquiring a high-resolution magnetic resonance image dataset of at least one limited body region having at least one anatomical structure of a patient, an overview image dataset is first acquired, using which an item of position information of the at least one anatomical structure is ascertained, the item of position information designating an exact position of the at least one anatomical structure and/or a relative position of the at least one anatomical structure relative to the reference body region. A high-resolution magnetic resonance image dataset of the anatomical structure is then created using the position information and the high-resolution magnetic resonance image dataset is evaluated. The evaluated high-resolution image data is then made available in electronic form.
