However, not all disturbing noises can be suppressed by means of hearing protection, so that high and / or disturbing noises are always present for the patient
In addition, the patient's lying comfort is limited by wearing hearing protection

Embodiment Construction

[0026] exist figure 1 A method according to the invention for determining and / or setting a desired volume for a magnetic resonance examination is shown in . The method according to the invention is preferably carried out during the planning of a queued magnetic resonance examination of a subject to be examined, eg patient 105 . During the planning of the magnetic resonance examination, at the start of the method, a magnetic resonance sequence 10 is manually selected by an operator via user interface 112 of magnetic resonance apparatus 100 in a first method step. The user interface 112 includes input means 113, such as a keyboard and / or a touch screen, and output means 114, such as a display. The operator thus carries out the selection 10 of the magnetic resonance sequence by means of the input device 113 .

[0027] By means of the selection of the magnetic resonance sequence by the operator, the control unit 111 of the magnetic resonance device 100 invokes and / or generates a...

Abstract

In a method and magnetic resonance apparatus to determine and / or adjust a noise volume for a magnetic resonance examination, a selection of a magnetic resonance sequence for the magnetic resonance examination of a subject to be examined hereby is made and an automatic calculation of an expected noise volume for the magnetic resonance examination is made in a volume determination unit using protocol parameters of the selected magnetic resonance sequence. Information about the expected volume is provided to an operator via a user interface.

Description

technical field [0001] The invention relates to a method for determining and / or setting the volume of a magnetic resonance examination, wherein a magnetic resonance sequence is selected for the magnetic resonance examination on a subject to be examined. Background technique [0002] Magnetic resonance examinations have hitherto been associated with a high noise load on the patient, wherein noise at a volume of 100 dB(A) or higher is generated during the magnetic resonance examination. These high noises are primarily caused by rapidly changing gradient fields, which induce twisting and / or vibrations in the gradient coil units of the magnetic resonance system and / or transmit energy to, for example, the housing of the magnetic resonance system. [0003] Therefore, in order to avoid a high noise load on the patient, the patient usually has to wear hearing protection during the magnetic resonance examination. However, not all disturbing noises can be suppressed by means of heari...
