Abstract

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.

First claim

The invention claimed is:

1 . An imaging system with wireless communication capability, comprising:
a gantry rotatable around a rotation axis, the gantry including a detector for recording, in plural spatial positions, measurement data in relation to a patient to be imaged; at least one radio receiver; at least one radio transmitter for generating a directed radio beam propagatable along a propagation axis to transmit the measurement data to the at least one radio receiver; wherein the radio transmitter is arranged at the rotatable gantry and is operable so that the propagation axis intersects the rotation axis in a location that is situated away from the rotatable gantry, and wherein the receiver is located at said location.

2 . The system of claim 1 , further comprising an examination table on which a subject to be imaged is located during imaging, and wherein said location is situated away from said table.

3 . The system of claim 1 , wherein the transmitter includes an array of antenna elements operating in concert to form the directed beam.

4 . The system of claim 1 , comprising a plurality of transmitters arranged around said rotation axis and on the rotatable gantry, with the respective propagation axes intersecting at said location.

5 . The system of claim 1 , wherein the imaging system is an X-ray imaging system.
