Abstract: An RF coil assembly for an MRI system may include a coil support and an RF coil. The coil support may include a base, a first adjusting arm and a second adjusting arm. The first adjusting arm is rotatably connected to the base and rotatable about a first axis relative to the base. The second adjusting arm is rotatably connected to the first adjusting arm and rotatable about a second axis relative to the first adjusting arm, the second axis being parallel to the first axis. The RF coil is rotatably connected to the second adjusting arm and rotatable about a third axis relative to the second adjusting arm, the third axis being parallel to the first axis. The position and angle of the RF coil can be flexibly adjusted so that the RF coil fits the examination subject more closely, thus helping to increase imaging quality.

Abstract: An anti-fog glass includes a glass body configured as a single layer or a multilayer stack; an active anti-fog layer disposed on the glass body and heating up when being provided with power; and a passive anti-fog layer disposed on the glass body and inhibiting fog from forming on the passive anti-fog layer. The passive anti-fog layer is a super hydrophobic coating and/or hydrophilic coating. Both the active anti-fog layer and the passive anti-fog layer are simultaneously disposed on the glass body to inhibit fog from forming. In this way, in a region of the glass body not covered by the active anti-fog layer, the anti-fog function is achieved by the passive anti-fog layer to a certain degree; in addition, in a region where the passive anti-fog layer itself cannot provide a desired anti-fog level, the active anti-fog layer together with the passive anti-fog layer provide a better anti-fog effect.

The signal processing unit is connected to the sound source sensor unit, the camera unit and the wireless communication unit. The camera unit is associated with the sound source sensor unit. When the sound source sensor unit recognizes a target signal, the signal processing unit sends a trigger signal to the camera unit, and then the camera unit is triggered to replay a surveillance video to determine whether or not a target really exists. Compared with the prior art, the device has the advantages of being good in safety, high in reliability and the like.

Abstract: A shoulder coil for a magnetic resonance system includes a receiving part. The shoulder coil also includes a transmitting part used for coupling a radio-frequency magnetic field of a body coil of the magnetic resonance system.

Abstract: In a method for acquiring magnetic resonance signals from a first shoulder or an opposite second shoulder of a patient, a shoulder coil anterior part and a shoulder coil posterior part are provided. A base plate is engageable with a moveable support element connecting the shoulder coil posterior part to the base plate to permit lateral movement and 90 degree rotation of the shoulder coil posterior part. With the base plate beneath the patient, the shoulder coil posterior part is placed below the first shoulder and the shoulder coil anterior part is placed above the first shoulder to permit acquisition of magnetic resonance measurements. To acquire signals from the opposite second shoulder, the shoulder coil posterior part is moved across the base plate to be positioned beneath the second shoulder and is rotated by 90 degrees. The shoulder coil anterior part is placed above the rotated shoulder coil posterior part.

Abstract: Improved patient comfort is provided by a symmetric local coil arrangement designed to support the production of an MRT image of a shoulder, wherein the housing of the local coil arrangement is composed of two separable parts. The symmetric local shoulder coil arrangement is designed to be useable for either of a right or left shoulder of a human subject by rotating the local coil arrangement about a rotational axis that is parallel to an axis of symmetry of the local shoulder coil and perpendicular to anterior and posterior members of the shoulder coil.

Abstract: In a system having a magnetic resonance imaging (MRI) apparatus and MRI-monitored medical equipment, the MRI-monitored medical equipment has an inductive coil built into the equipment that receives magnetic resonance signals from a subject and generates inductive electromagnetic signals according to the received magnetic resonance signals. The magnetic resonance imaging system has at least one reception coil that is positioned externally of the MRI-monitored medical equipment and that is connected to the magnetic resonance imaging system via a cable. The reception coil receives the electromagnetic signals that are generated by the inductive coil that is built into the medical equipment.

Abstract: A receiving device for an MRI (magnetic resonance imaging) system has multiple receiving coils. In the same imaging acceleration direction, a junction region is formed between adjacent receiving coils. An additional receiving coil is arranged on the junction region. The additional receiving coil covers at least partially a line of strong phase variation in sensitivity at the boundary of said junction region. This receiving device alleviates the problem of poor sensitivity to MRI signals in the junction region in the imaging acceleration direction, so as to improve the imaging quality in the junction region, and thus improving the overall imaging quality.

Abstract: In a method and magnetic resonance (MR apparatus for reducing aliasing artifacts in the imaging for MR-monitored high intensity focused ultrasound HIFU therapy, a primary coil is used to receive the MR signals, and an additional coil is provided to receive interfering MR signals that form aliasing artifacts in the MR-monitored HIFU therapy imaging. The MR signals received by the primary coil and the interfering MR signals received by the additional coil are concurrently acquired. The interfering MR signals received by the additional coil are removed from the MR signals received by the primary coil. MR images are generated based on the MR signals with the interfering MR signals removed. Aliasing artifacts caused by the interfering MR signals thus are removed from the MR images without reducing the resolution of the scanned body parts in the MR images. In addition, the MR scanning time can be—maintained by using a proper phase oversampling technology in the concurrent signal acquisition.

In the method, a receiving coil is used to receive signals in a magnetic field, wherein the receiving coil is perpendicular to the direction of the magnetic field. By using the apparatus and the corresponding method since the receiving coil can have a loop type design, the signal-to-noise ratio is increased.

Abstract: A magnetic resonance coil has an antenna portion for accommodating a body part to be examined, the antenna portion is formed by a number of constituent units connected in series, the positions between various constituent units are relatively movable. By moving the positions between the constituent units, a portion of the area between at least two constituent units overlaps. By increasing or reducing the number of the constituent units, or by adjusting the overlapped area between the constituent units, one pair or a number of pairs of the constituent units are made to overlap completely, so as to achieve the adjustment of the size of the antenna portion to accommodate a body part to be examined, and to make said antenna portion as close as possible to the body part to be examined, so as to obtain a signal with a relatively high signal-to-noise ratio, and to obtain a relatively high imaging quality.

Abstract: An examination bed for use in a magnetic resonance imaging system, has a bed board, a bottom antenna for an RF coil and a main body antenna for an RF coil. The bottom antenna is integrated in the inside or surface of the bed board, and forms a loop with the main body antenna, to form an RF coil. The thickness of the base plate is thereby reduced by integrating the bottom antenna into the bed board, thus increasing the available space to make the most of the limited space of the magnetic field for examination so that the examination bed can be used for those patients or other tested objects that would otherwise be oversized for the bed.
