摘要： 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.

摘要： A pulse sequence is disclosed for operating a nuclear magnetic resonance tomography apparatus for producing images having different T.sub.2 contrast. A signal for the gradient-echo imaging is first acquired after excitation of the nuclei subsequently, the magnetization, which is already prepared for imaging, is refocused by a 180.degree. radio-frequency pulse, and a second echo is measured in the presence of a readout gradient. Independent images having different T.sub.2 contrast can be reconstructed with the gradient echo and with the spin echo. It is thus possible to simultaneously measure a gradient echo image having a significantly lower T.sub.2 contrast during the measuring time for a spin echo image.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A magnetic resonance system that has a magnet system that generates magnetic fields in an excitation region, allowing nuclei in an examination subject in the excitation region to be excited to emit a magnetic resonance signal. A reception antenna device with multiple local coils for reception of the magnetic resonance signals is arranged in proximity to the examination subject, and has a base part and an attachment part. The attachment part can be placed on the base part such that the examination subject is located between the base part and the attachment part (6). The multiple local coils are respectively connected with an evaluation device for evaluation of magnetic resonance signals. To simply and reliably couple the antenna devices to an evaluation device with optimally few electrical conductors being located in the excitation region, the multiple local coils in the attachment part are respectively connected with the evaluation device via a base coupling element that is arranged at a predetermined base part location on the base part and an attachment coupling element is arranged at a predetermined attachment part location on the attachment part. The magnetic resonance signal received by the local coil can be fed to the evaluation device via the attachment coupling element and the base coupling element and as long as the attachment part is placed on the base part.
