Description

Technical Field

[0001] The utility model relates to a magnetic resonance device, which has a magnet unit, a patient accommodation area at least partially surrounded by the magnet unit, and a patient communication unit, wherein the patient accommodation area is configured to accommodate a patient for magnetic resonance examination. Background Art

[0002] Regardless of the grammatical gender of specific terms, people with male or female gender identities are included.

[0003] During magnetic resonance examination, the patient is located in an examination room where a magnetic resonance device is internally provided. Here, the patient is positioned within the patient accommodation area for magnetic resonance examination. In contrast, medical operators who supervise the magnetic resonance examination, such as doctors, stay in a control room during the magnetic resonance examination. The medical operator can control and monitor the magnetic resonance examination from the control room.

[0004] In order to communicate with the patient during magnetic resonance examination, the magnetic resonance device usually has a patient communication unit. The patient communication unit is used to transmit information and / or instructions to the patient during magnetic resonance examination. For example, in this case, breathing instructions required for magnetic resonance examination can be transmitted to the patient, such as especially breath-holding instructions and / or breath-holding signals, which inform the patient when to hold their breath. This is particularly important in chest examinations. In addition, the remaining scan duration and / or remaining examination time can also be informed to the patient by means of the patient communication unit.

[0005] So far, such information and / or instructions have been transmitted to the patient by means of a sound output unit, such as in the form of headphones, worn by the patient during magnetic resonance examination.

[0006] On the contrary, there are many difficulties in arranging a conventional display and / or monitor within the patient accommodation area of the magnetic resonance device. Therefore, the magnetic resonance examination may be particularly interfered by the interference signals of the electronic devices of the display, which may lead to unwanted artifacts in the detected image data and / or cause measurement repetition. In addition, the display is located within a very strong magnetic field, such as 1.5T or 3T, which also causes interference to the electronic devices of the display itself, thus resulting in interference to patient communication. The interference to patient communication will have a negative impact on the patient, so that individual measurements of the magnetic resonance examination may have to be repeated. Another difficulty in arranging a through-display is the power supply of the display, which will also cause interference to the magnetic resonance examination. Summary of the Utility Model

[0007] The present utility model is particularly based on the following object: to provide visual patient communication in a simple manner during magnetic resonance examination of a patient. This object is achieved by a magnetic resonance device according to the present utility model. Advantageous design solutions are described below.

[0010] The magnetic resonance device preferably includes a magnet unit for detecting medical and / or diagnostic image data. In this case, the magnet unit includes a basic magnet, a gradient coil unit, and a radio frequency antenna unit. The radio frequency antenna unit is fixedly arranged within the magnet unit in this case.

[0011] The basic magnet is configured to generate a uniform basic magnetic field, which has a defined magnetic field strength, for example, a magnetic field strength of 0.55T or 1.5T or 3T or 7T, etc. In particular, the basic magnet is configured to generate a strong, constant, and uniform basic magnetic field. The gradient system is configured to generate a magnetic field gradient, which is used for position encoding during imaging. The radio frequency antenna unit is configured to emit radio frequency pulses and / or excitation pulses to generate magnetic resonance signals.

[0012] For magnetic resonance examination, a patient, in particular the area of the patient to be examined, is positioned in the patient accommodation area of the magnetic resonance device. The isocenter and / or field of view (FOV) of the magnetic resonance device are preferably arranged within the patient accommodation area. The FOV preferably includes the detection area of the magnetic resonance device, within which the conditions for detecting medical image data, in particular magnetic resonance image data, exist within the patient accommodation area, such as a uniform basic magnetic field. The isocenter of the magnetic resonance device preferably includes the following area and / or point within the magnetic resonance device, which has optimal and / or ideal conditions for detecting medical image data, in particular magnetic resonance image data. In particular, the isocenter includes the most uniform magnetic field area within the magnetic resonance device.

[0013] To move the patient, in particular the area of the patient to be examined, into and / or position it within the patient accommodation area, the magnetic resonance device includes a patient support device. The patient support device here has an examination couch, where the examination couch is configured to be movable relative to the magnet unit. Preferably, in this case, the examination couch is configured to be movable within the patient accommodation area along the longitudinal direction of the examination couch and / or along the longitudinal direction of the patient accommodation area in order to position the patient in an examination position within the patient accommodation area.

[0014] The patient communication unit is configured for communication between the user, in particular the operator supervising the magnetic resonance examination, and the patient during the magnetic resonance examination. For this purpose, the patient communication unit has a display unit on the patient side, which display unit is arranged within the examination room including the magnet unit. In addition, the patient communication unit can include a second communication unit, which second communication unit is arranged on the user side, in particular within the control room, from where the magnetic resonance examination is controlled and / or monitored by a medical operator. For example, the second communication unit can include an input unit for inputting information and / or instructions that should be transmitted to the patient.

[0015] By means of the display unit, instructions and / or information, in particular examination-related instructions and / or information, should be transmitted to and / or informed to the patient during the magnetic resonance examination. For example, the remaining examination time can thus be informed to the patient.

[0018] Such displays, especially electronic paper displays and / or electronic ink displays, have the following advantages: The information and / or instructions shown can be persistently displayed and / or presented without an energy input. In particular, such displays, especially electronic paper displays and / or electronic ink displays, only require energy when changing the displayed content and / or the presented content, such that the required energy is very low. For example, electronic paper displays and / or electronic ink displays require a current in the range of a few hundred mA. In particular, the continuously powered electronics of the display unit can thus be advantageously dispensed with during a magnetic resonance examination. In particular, the energy requirement can be kept very low, thereby also keeping the undesired interaction between the display unit and the magnet unit very small and / or preventing said interaction. For example, the display unit can be configured to change the displayed content of the electronic paper display and / or the electronic ink display only during a measurement pause, especially during the pause between two radiofrequency pulses to be emitted. In particular, the undesired interference of the display unit and / or the magnetic resonance data acquisition can be reduced and / or prevented in this way. Thus, visual information can be provided to the patient during a magnetic resonance examination in a structurally simple manner and method.

[0019] Furthermore, the display unit, especially an electronic paper display and / or an electronic ink display, can be configured to be particularly compact and space-saving.

In particular, the design of the display unit having an energy storage element has the following advantages: A constant current and / or a constant voltage can be provided for the operation of the display unit. In addition, the voltage peaks that occur during energy acquisition are not directly transmitted to the electronics of the display unit, but rather a smoothing effect is produced by the energy storage element, especially the capacitor.

Preferably, the second wireless module is located outside the patient accommodation area. Preferably, communication is carried out between the two wireless modules with a frequency set outside the transmission spectrum and / or the reception spectrum of the magnetic resonance device.
