SYSTEM AND METHOD FOR REAL-TIME NOISE REDUCTION IN MRI DATA ACQUISITION
A method and system for real-time reduction of noise during MRI data acquisition is disclosed. At least one antenna is placed in proximity to, or within the cavity of, a standard MRI apparatus, and in connection with a standard data acquisition setup. The data acquisition by the antenna is synchronized to the MRI pulses. Any residual signal is defined as noise; if a particular data subset is deemed to be noisy, the noise can be reduced or eliminated by, for example, remeasuring the data subset or by direct subtraction of the noise from the measured signal. By placing one antenna within and one in proximity to the MRI apparatus, the system and method can also be used to determine the actual level of RF shielding in the MRI apparatus.
A magnetic shielding mechanism for preventing penetration of metallic objects through an aperture, towards the open bore of an magnetic resonance imaging device, where the magnetic field is maximized. The magnetic resonance imaging device produces a fringing magnetic field that decreases with increasing distance (L) from the aperture. The mechanism includes at least one magnet with a magnetic field. The mechanism is affixed at a distance from the aperture of magnetic resonance imaging device.

MEANS AND METHODS FOR REDUCING THE ELECTROMAGNETIC ENERGY PROPAGATION FROM AN MRD'S MAGNET-BORE TO THE OUTER ENVIRONMENT SURROUNDING SAID MAGNET, AND VICE VERSA
The present invention discloses in an open bore MRD (100) having a volume of interest for imaging a body portion (31) and an inlet aperture for inserting the body portion within the bore, and an electrically earthed protecting sleeve (22) for reducing propagation of electromagnetic energy from the magnet bore to the outer environment surrounding the magnet and vice versa. The sleeve has a distal portion (23) insertably locatable within the bore and a proximal portion (22) attachable to the MRD aperture. The length and diameter of the sleeve is shaped and sized such that non-imaged portions of the body portion are within the sleeve, whilst the imaged portion protrudes from the distal end of the sleeve.
The present invention provides a magnetic shielding mechanism (MSM) for preventing penetration of metallic objects through an aperture, so that penetration into the open bore of an MRI device (MRD), where the magnetic field (B) is maximum, is prevented. The MRD produces a fringing magnetic field (BF/L) which decreases with increasing distance (L) from the aperture; the MSM comprises at least one magnet with a magnetic field BMSM; and the MSM is affixed at a distance LMSM from the MRD's aperture so that,at any distance L, BMSM >> BF/L.

Means and methods for reducing the electromagnetic energy propagation from an MRD's magnet-bore to the outer environment surrounding said magnet, and vice versa
An electrically earthed protecting sleeve that reduces the electromagnetic energy propagation from a magnetic bore to the outer environment surrounding a magnet. The sleeve has a distal portion located within an open bore of an magnetic resonance device (MRD) and a proximal portion attachable to an aperture of the MRD. The sleeve accepts a non-imaged portion of a body portion inserted within the bore while the imaged portion protrudes from the distal end of sleeve.
An integrated metal detector-portable medical device adapted to identify metals in a human body, where the metal detector is in connection with the portable medical device. The metal detector includes: at least one transmitter adapted to induce a magnetic field generated by a metal; at least one sensor adapted to detect the magnetic field generated by the metals to be detected; and at least one signaling mechanism adapted, upon detection of a magnetic field, to alert the user of identification of metals, if the intensity of a magnetic field is above a predetermined value.
