摘要:
An apparatus for determining a position of a medical instrument within a patient receiving zone of a magnetic resonance tomography device is provided. The apparatus includes a sensor and a computing and control device. The sensor is arranged on or in the medical instrument, includes at least one magnetic field sensor for obtaining measured values of a magnetic flux density, and may be connected to the computing and control device for data transfer purposes. The computing and control device is embodied to control magnetic fields of the magnetic resonance tomography device and to determine the position of the medical instrument. The measured values of the at least one magnetic field sensor and control signals for controlling the magnetic fields of the magnetic resonance tomography device are included in the determination of the position of the medical instrument.

A magnetic resonance device having a tunnel for accommodating a patient is disclosed. The magnetic resonance device has a lining which clads both the tunnel and the end faces adjacent to it. At least one OLED, LCD or LED display panel is movably disposed on or in the lining cladding the tunnel or the lining cladding the end face. The display panel disposed in the tunnel is disposed on a bracket which can travel linearly along the lining and/or along the circumference of the lining. The display panel disposed on the end-face lining can travel and/or be tilted vertically.

The present embodiments relate to a method and a local coil arrangement for a magnetic resonance tomography system. The local coil arrangement includes an antenna element for the reception of signals from an object under examination. The local coil arrangement also includes an A/D converter for the conversion of analog signals received with the antenna element into digitized signals, and a memory configured for the storage of the digitized signals.
摘要:
A local coil for magnetic resonance applications receives analog magnetic resonance signals excited by an excitation signal in an examination object using a plurality of receive antennas. The local coil digitizes the received analog magnetic resonance signals and stores the digitized magnetic resonance signals in digital form in a write-in sequence in an internal local coil memory. The local coil reads the digitized magnetic resonance signals stored in the internal local coil memory out of the internal local coil memory in a read-out sequence that is different from the write-in sequence and transfers the digitized magnetic resonance signals to a control and evaluation device of a magnetic resonance unit.

At least one embodiment of the invention relates to bone marrow precursor cells or bone marrow cells of a patient, the cells labeled with at least one contrast agent suitable for an imaging method, for use in an imaging method for diagnosing a metastasizing cancer, wherein the local accumulation of the labeled precursor cells or bone marrow cells indicates the presence of a metastasizing tumor growth. At least one embodiment also relates to a method for imaging a metastasizing tumor tissue in a patient, wherein a) bone marrow precursor cells or bone marrow cells are extracted from a patient, b) these precursor cells or bone marrow cells are labeled with at least one contrast agent suitable for an imaging method, c) the precursor cells or bone marrow cells thus labeled are retransplanted or reinjected into the patient, and d) the presence of metastasizing tumor cells is depicted with an imaging method. At least one embodiment also relates a method for imaging a metastasizing tumor tissue, wherein a suitable imaging method is used to image bone marrow precursor cells and/or bone marrow cells that are accumulated in a metastasizing tumor tissue and labeled with at least one contrast agent suitable for an imaging method.
