A method is for determining a heating effect of an imaging sequence of a second imaging modality on a detector of a first modality of a combined imaging device in dependence of a reference imaging sequence of the second imaging modality. A further method is for compensating a heating effect of an imaging sequence of a second imaging modality on a detector of a first modality of a combined imaging device. Furthermore, a combined imaging device includes a magnetic resonance imaging device and a first modality including a detector and a temperature compensation unit configured to compensate for a temperature variation of the detector. The combined imaging device is configured to perform a method for determining a heating effect of an imaging sequence of the magnetic resonance imaging device on the detector of the first modality in dependence of a reference imaging sequence of the magnetic resonance imaging device.

An imaging apparatus has an MRT system with an MR receiving antenna configured to receive a first receive signal containing an MR signal from an object to be examined during an examination period. The imaging apparatus includes a modality for examining the object and/or for acting on the object via mechanical or electromagnetic waves, wherein the modality has an electronic circuit. The imaging apparatus includes an auxiliary antenna arranged and configured to receive a second receive signal containing an interference signal generated by the electronic circuit during the examination period. The imaging apparatus has a processing system configured to suppress interference in the first receive signal based on the first and the second receive signal.

A medical imaging device, such as a computed tomography device and/or a magnetic resonance device, includes at least one movable component. The at least one movable component can include a patient couch, and the medical image device can further include an operating device for controlling the operation of the at least one component. The operating device can include a touch-sensitive and force-sensitive interface (e.g. touchscreen display) having at least one touch sensor and at least one force sensor that measure the strength of a touch.

A medical imaging apparatus with a medical scanner unit and at least one display is described, as well as a method for actuating at least one display of a medical imaging apparatus. The techniques disclosed are based on a medical imaging apparatus with a medical scanner unit, a computing unit which is connected to a master unit, and at least one display. The at least one display may include a slave unit, and the master unit may be connected to the slave unit by means of a data connection.

A flexible design of a transmission system for a magnetic resonance tomography apparatus has multiple radio-frequency control units, connectors that are connected to the radio-frequency control units, a unit to which at least one first connector is connected, which connector is also connected to a first radio-frequency control unit of the radio-frequency control units. The unit is connected via a connector to only some&#x2014;in particular only one&#x2014;of the radio-frequency control units. One of these few radio-frequency control units is connected to an additional radio-frequency control unit via an additional connector.

Scalable multichannel transmitter system for an MR transmission array

Optimized transmission system for an MRT is achieved by a device and a method to generate transmission signals () via multiple transmission units of a transmission system for a magnetic resonance tomography system, wherein transmission data are respectively received from the transmission units via a transmission data input, received transmission data are stored in transmission data memory elements of the transmission units, transmission signals representing stored transmission data are generated with transmission data (stored in transmission data memory elements) by transmission signal transmission units of the transmission units, and the generation of transmission signals proceeds simultaneously via the transmission signal transmission units.

In a transmission error logging device, method and computer-readable medium for logging transmission errors that occur on a high speed transmission route of a medical technology diagnostic apparatus, the in-feed port for a signal is provided on the high speed transmission route and an error signal is generated upon detection of an error. The transmission volume is detected by a transmission volume counter and the number of errors is detected by a transmission error counter. The transmission volume counter makes a transmission volume count, representing the transmission volume, available as an output from the transmission volume counter, and the transmission error counter makes a count of the number of errors detected by the error detection device available at an output of the transmission error counter.

Error detection on medical high speed transmission routes

A modulator for radio-frequency signals designed an entirely digital modulator has two mixer stages connected in series. The first mixer stage implements with a relatively low first sample rate a frequency mixing with a first oscillator frequency that is adjustable with high precision. The second mixer stage implements a frequency mixing with a significantly higher second sample rate and with a relatively coarsely adjustable second oscillator frequency. The downstream second mixer stage, in the case of a single mixer stage, the mixer stage, has at least two phase accumulators that are incremented with the higher second sample rate but with different incremental values. The output signal of at maximum one of the phase accumulators is evaluated at any point in time.
