摘要： An imaging system (MIS), optionally a medical imaging system, with wireless communication capability and related method. The imaging system comprises a gantry (RG) rotatable around a rotation axis. The gantry includes a detector device (D) capable of recording, in plural spatial positions, measurement data in relation to a subject (such as a patient) (PAT) to be imaged. The system also includes a radio transmitter (TX) for generating a directed radio beam propagatable along a propagation axis to transmit the measurement data to a radio receiver (RX). The radio transmitter (TX) is arranged at the rotatable gantry and is operable so that the propagation direction intersects the rotation axis in a location that is situated away from the rotatable gantry.

摘要： The present invention provides a rheology module (200) for use in a magnetic resonance (MR) rheology imaging system (110), whereby the rheology module (200) is adapted to introduce mechanical oscillations into a subject of interest(120), comprising a housing(202), a mechanical oscillator unit(204), which extends at least partially outside the housing (202) and is movable relative to the housing(202), and a transducer (206) for moving the oscillator unit(204),whereby the rheology module (200) comprises at least one radio frequency (RF) antenna unit(210, 212), which comprises at least one RF coil(214, 216).With the RF antenna device integrated into the rheology module, an antenna placement close to a region of interest (ROI) can be achieved to improve the MR imaging capabilities of a MR rheology imaging system. Thus, imaging of the ROI can be performed more efficiently. Furthermore, connection and cabling can be facilitated, since only one module has to be connected to generate the oscillation and to operate the RF antenna device.
