Embodiment Construction

[0049] figure 1 A medical imaging device 10 is shown schematically. In this exemplary embodiment, the medical imaging device 10 is formed by a magnetic resonance device. In a different configuration of the medical imaging device 10 , it can also be formed by a computed tomography device and / or a PET device (Positron Emission Tomography) and / or other medical imaging devices 10 that are considered expedient by the person skilled in the art.

[0050] The magnetic resonance device comprises a detector unit 11 with a magnet unit 12 having a superconducting main magnet 13 for generating a strong and in particular constant main magnetic field 14 . Furthermore, the magnetic resonance system has a patient receiving area 15 for receiving a patient 16 . In the present exemplary embodiment, the patient receiving area 15 is designed cylindrically and is surrounded cylindrically by the magnet unit 12 in the circumferential direction. In principle, however, different configurations of the...

Abstract

A method for wireless transmission of acoustic cardiac signals during a medical imaging examination is provided. The acoustic cardiac signals are acquired at a sampling frequency using an optical microphone, and the sampling frequency spans one period duration. The wireless transmission of the acoustic cardiac signals is accomplished by a transmission device that includes a controller and a transmission unit. The transmission unit includes a signal modulation unit including a transmit diode and a receive diode. The method includes activating the transmit diode using the controller for a time interval including the activation time. The activation time is less than a period duration. The method includes emitting a signal using the transmit diode during the activation time. The emitted signal is optically modulated based on the acoustic cardiac signals. The method also includes acquiring the modulated signals using the receive diode during the activation time, and wirelessly transmitting the signals.

Description

technical field [0001] The invention relates to a method for the wireless transmission of heart sound signals during medical imaging examinations, wherein the heart sound signals are acquired at a sampling frequency by means of an optical microphone and the sampling frequency includes a cycle time, wherein the transmission is performed by means of a transmission device with a control unit and a transmission unit The transmission of the heart sound signal, wherein the sending unit includes a signal modulating unit with a sending diode and a receiving diode. Background technique [0002] Medical imaging, such as magnetic resonance imaging, preferably includes several transmit-receive cycles, which are combined into one image by post-processing. For body regions of the patient that move, for example due to the patient's heartbeat, the image acquisition must always take place in the same phase of the movement for each cycle. For this purpose, for magnetic resonance imaging, a t...
