A method for generating a spatially resolved magnetic resonance dataset using a coil arrangement includes providing at least one correction datum based on receiver characteristics of the coil arrangement. The method also includes providing a magnetic resonance dataset with spatially resolved signal intensity data, and correcting the at least one signal intensity datum in the magnetic resonance dataset by the correction datum before or after providing the magnetic resonance dataset.

APD-based PET modules are provided for use in combined PET/MR imaging. Each module includes a number of independent, optically isolated detectors. Each detector includes an array of scintillator (e.g. LSO) crystals read out by an array of APDs. The modules are positioned in the tunnel of a MR scanner. Simultaneous, artifact-free images can be acquired with the APD-based PET and MR system resulting in a high-resolution and cost-effective integrated PET/MR system.

A positioning apparatus configured to actively assist the support, positioning, or support and positioning of a patient on a patient support apparatus is provided. The positioning apparatus includes a sliding bearing unit to allow the positioning apparatus to be supported in a movable manner on the patient support apparatus, and a bearing unit with at least two bearing regions. At least a first of the at least two bearing regions is configured to support and/or provide support on the patient support apparatus, and at least a second of the at least two bearing regions is configured to assist the positioning of the patient.

In order to increase the signal to noise ratio, and thus increase the quality of images produced during pediatric MRI, a pediatric RF coil assembly includes a head coil and a flexible body coil in a single dedicated device shaped and sized for a child. The flexible body coil may be operable to at least partially surround and abut the body of the child located on the pediatric RF coil assembly, while the head coil may at least partially surround and abut the head of the child located on the pediatric RF coil assembly. In order to optimize workflow, the child may be positioned on the pediatric RF coil assembly in a first room and moved to a second room including an MRI system after the child is brought to sleep or sedated in the first room. The pediatric RF coil assembly and the child may be moved to the second room using a handle rotatably attached to the pediatric RF coil assembly, and may be positioned on a patient table of the MRI system when the imaging process is to begin.

Pediatric coil assembly

A magnetic resonance system has a patient receptacle and a base body. The patient receptacle has a subframe and a patient bed supported thereon so as to move a patient thereon through the base body. The base body has a basic field magnet system, a gradient system and an RF system that are operable to obtain an analog magnetic resonance signal from the patient. The patient receptacle has a signal conversion device composed of an A/D converter, a modulator, and a transmitter. The base body has a signal conversion device composed of a receiver and a demodulator. The A/D converter receives the magnetic resonance signal and digitizes it. The modulator modulates a carrier signal with the digitized magnetic resonance signal. The transmitter transmits the modulated carrier signal via an air gap to the receive. The receiver receives the transmitted carrier signal. The demodulator extracts the digitized magnetic resonance signal from the received carrier signal by demodulation and supplies it to an evaluation device for continuing evaluation.

A patient bed, in particular for a magnetic resonance apparatus, has at least one socket for accommodation of a plug of a device (in particular a local coil) to be arranged at the patient bed. A generation of a force generator that automatically assists or effects the insertion or the unplugging of the plug is built into the socket or is associated with the socket.

A radio-frequency transmission device for a magnetic resonance system to generate magnetic resonance exposures of an examination region of an examination subject, has: a first radio-frequency transmission antenna that emits radio-frequency signals in the examination region, a radio-frequency amplifier that supplies the first radio-frequency transmission antenna, with radio-frequency signals with a predetermined radio-frequency transmission power, and a second radio-frequency transmission antenna fashioned to label a medium flowing in the examination region and/or examination regions via emission of labeling radio-frequency signals, such that the medium can be identified in the generated magnetic resonance exposures of the examination region. The second radio-frequency transmission antenna is coupled with the radio-frequency amplifier to supply the first radio-frequency transmission antenna, such that it likewise supplies the second radio-frequency transmission antenna with radio-frequency signals with a predetermined radio-frequency transmission power for the emission of radio-frequency labeling signals.
