Embodiment Construction

[0063] figure 1 The basic setup of a system according to an embodiment of the invention is shown diagrammatically. The system includes an MRI system control unit 120 . The MRI system control unit (scanner host) calculates the gradient waveform according to the selected MRI sequence. These waveforms are sent to the gradient amplifier 110, and the resulting gradient current is introduced to the gradient coils, thereby producing different types of sounds. The gradient system is part of the MRI system 105 . This part of the setup represents a presently common practice of magnetic resonance gradient control. Embodiments of the invention propose extending the scanner host with interface 122 to access the calculated (future) gradient waveform and its (precise) timing, including the (absolute) time when the waveform will be applied. Interface 122 is accessible during scanner operation and will deliver information about currently anticipated future waveforms. If a scan is aborted ...

Abstract

It is an object of the invention to increase the predictability of the MRI exam for the patients. This object is achieved by a method for classifying sound of a magnetic resonance imaging sequence into a sound category, wherein the magnetic resonance sequence comprises a one or more sound blocks, wherein individual sound blocks have signal characteristics and wherein sound blocks having similar characteristics are to be classified into the same sound category, the method comprising the steps of: - receiving information about one or more gradient waveforms to be used in the magnetic resonance imaging sequence and; - using a classification algorithm to map the waveform information to a sound category and; - allocating a visual to the sound category.

Description

technical field [0001] The invention relates to the field of magnetic resonance imaging. Background technique [0002] During Magnetic Resonance Imaging (MRI), acoustic noise is generated by gradient coils. As a result, the patient may feel uncomfortable during the MRI examination. As a result, many adults experience nervousness while undergoing an MRI, and children often receive sedation or general anesthesia before the scan. Anesthesia / sedation at a young age can have long-term negative health effects. In addition, examinations under sedation were about three times as expensive as sobriety examinations, and examinations under anesthesia were nine times as expensive. [0003] US2013 / 0275086A1 discloses a method and a magnetic resonance apparatus for determining and / or adjusting the noise volume of a magnetic resonance examination, whereby selection of a magnetic resonance sequence for a magnetic resonance examination of an object to be examined is performed, and in the v...
