The disclosure herein provides methods, systems, and devices for tracking motion of a patient or object of interest during biomedical imaging and for compensating for that motion in the biomedical imaging scanner and/or the resulting images to reduce or eliminate motion artifacts. In an embodiment, a motion tracking system is configured to overlay tracking data over biomedical imaging data in order to display the tracking data along with its associated image data. In an embodiment, a motion tracking system is configured to overlay tracking data over biomedical imaging data in order to display the tracking data along with its associated image data. In an embodiment, one or more detectors are configured to detect images of a patient, and a detector processing interface is configured to analyze the images to estimate motion or movement of the patient and to generate tracking data describing the patient's motion. The detector processing interface is configured to send the tracking data to a scanner controller to enable adjustment of scanning parameters in real-time in response to the patient's motion.

The present invention relates to a patient support. In order to improve safety for MRI scanning protocols, a patient support is provided for an MRI scanner. The patient support comprises a braking device for deaccelerating the patient support when being transferred relative to the MRI scanner. The braking device comprises at least one non-magnetic electrically conductive element. The at least one non-magnetic electrically conductive element is configured to adjust one or more eddy currents induced in response to motion in a magnetic field of the MRI scanner to provide a counter force against an attractive force between the patient support and the MRI scanner, thereby creating an adjustable braking effect.

A radio frequency (RF) system comprises an RF-array of antenna elements, a regulating arrangement to tune the antenna elements' impedances and a camera system to acquire image information of the RF-array. An analysis module is provided to derive operational settings such as resonant tuning settings, decoupling and impedance matchings of the antenna elements' impedances from the image information. The image information also represents the actual impedances and resonant properties of the RF-array. From the image information appropriate impedance settings can be derived that are the tuning parameters to render the RF-array resonant.

A radio frequency (RF) receiving apparatus (10) includes a first and second omnidirectional RF antennas (20) at different spatial locations or orientations, a first and second RF receivers (24), each connected to a corresponding one of the first and second omnidirectional RF antennas (20), and a controller (32) connected to the first and second RF receivers (24). The first and second RF receivers (24) receive and demodulate RF signals of at least first and second carrier frequencies to recover data packets from at least a first device which transmits data packets on the first carrier frequency RF signal and a second device which transmits data packets on the second carrier frequency RF signal. The controller (32) is configured to control the RF receivers to cycle between receiving and demodulating the first carrier frequency RF signals concurrently to recover redundant data packets from the first device, and receiving and demodulating the second carrier frequency RF signals concurrently to recover redundant data packets from the second device. The apparatus can be used to wirelessly transmit physiological patient monitoring data (e.g. an ECG signal) in the highly reflective environment of an MRI system.

A magnetic resonance imaging system adaptively and dynamically adjusts color and brightness of illuminators mounted on the inside of a bore in response to a scan sequence used for magnetic resonance imaging or the state of a patient in order to relieve discomfort during magnetic resonance imaging. An illuminator control unit selects and determines optical characteristics of the illuminators in response to a scan sequence or the state of a patient.

A mobile computer suitable for use in an MRI environment is disclosed. The mobile computer includes at least one shielded cavity in which the electronics for the mobile computer are inserted. The shielded cavity inhibits undesirable emissions from the mobile computer from affecting the quality of the image obtained by the MRI scanner and inhibits electrical interference generated by the dynamic magnetic fields in the MRI scanner from affecting the performance of the mobile computer. In addition, the components used in the mobile computer are selected from non-ferrous materials and are arranged in a manner to minimize interaction between the mobile computer and the MRI scanner.

A method and magnetic resonance apparatus for acquiring a communication signal of a person situated within a magnetic resonance examination room. The method includes acquiring an item of position information of the person using an acquirer, adjusting at least one microphone of a microphone array on the basis of the acquired position information, and acquiring communication signals of the person using the microphone array.

A medical system (300) comprises a medical examination apparatus (302) and a wearable patient device (100). The medical examination apparatus (302) comprises an examination zone for a patient (304), and the wearable patient device (100) comprises a user interface operable by a hand of the patient when the patient (304) is positioned in the examination zone of the medical examination apparatus (302). The wearable patient device (100) is communicatively connected with the medical examination apparatus (302) via a wireless connection, for sending a control command corresponding to input received from the patient via the user interface of the wearable patient device (100), the control command being adapted to control a patient-controllable part or parameter (308) of the medical examination apparatus (302).

A medical imaging apparatus is provided. The medical imaging apparatus includes a table on which a subject lies and that carries the subject; a gantry that forms an internal space and scans the subject carried into the internal space; a screen unit mounted on the gantry or outside the gantry; and an image projector that projects an image onto the screen unit. In accordance with embodiments of the medical imaging apparatus, various content may be provided for a person subject to scanning to relieve his/her boredom or inconvenience during the scanning process.

A motion compensation system for tracking and compensating for patient motion during a medical imaging scan comprises an optical marker comprising an optically visible pattern and a mounting portion; a first optical detector positioned to digitally image the optically visible pattern along a first line of sight; a second optical detector positioned to digitally image the optically visible pattern along a second line of sight; a tracking engine configured to determine a pose of the object in six degrees of freedom by analyzing images from the first and second optical detectors; and a controller interface configured to generate tracking information based on the pose and to electronically transmit the tracking information to a scanner controller to enable compensation within a medical imaging scanner for object motion.
