Abstract: The invention relates to a method of MR imaging of an object (10) placed in an examination volume of a MR device (1). It is an object of the invention to enable MR imaging using a radial (or spiral) acquisition scheme with a reduced level of motion artefacts. The method of the invention comprises the following sequence of steps: —detecting a momentary motion—induced displacement (?) of the object (10); —attributing the detected displacement (A) to a motion state (M1-M5), each motion state (M1-M5) corresponding to one of a plurality of contiguous ranges of displacements (?); —determining angular coordinates of a radial or spiral k-space profile by incrementing the angular coordinates individually for each motion state (M1-M5) starting from initial angular coordinates; —acquiring the k-space profile; —repeating steps a-d a number of times; and —reconstructing an MR image from at least the k-space profiles attributed to one of the motion states (M1-M5).

Abstract: The invention provides for a medical imaging system (100, 300) comprising: a memory (110) for storing machine executable instructions (120) and a processor (104) for controlling the medical imaging system.

Abstract: The invention provides an apparatus (1) for magnetic resonance (MR) examination of a subject (S), comprising: an examination region (3) for accommodating the subject (S) during the MR examination; a radio-frequency system (5) for transmission of a radio-frequency (RF) signal or field into the examination region (3) during the MR examination; and a temperature control system (6) for controlling the temperature of the subject (S) in the examination region (3) during the examination. The temperature control system (6) is configured to actively control or regulate an environment of the subject (S), and thereby the temperature or thermal comformt of the subject (S) based upon a detected and/or an expected temperature of the subject (S) during the MR examination.
