Abstract: A robust MR compatible ECG monitor (40) includes a connector (50) for connecting ECG electrode leads (44) to an internal circuit board (52). The connector (50) includes connector pins (54) that run parallel to the circuit board (52) and tangentially contact solder pads (56) of the circuit board (52) at the edge of the circuit board (52), eliminating sharp or right angle turns in conduction paths. The connector prevents movement of the connections due to mechanical stresses in all ranges of motion relative to four degrees of freedom, including translation, pitching, yawing, and rolling.

Abstract: In a magnetic resonance imaging apparatus according to an embodiment, a transmitting coil applies a radio-frequency magnetic field to a subject placed in a static magnetic field. A receiving coil receives a magnetic resonance signal emitted from the subject owing to an application of the radio-frequency magnetic field. A balun is connected to the receiving coil, and suppresses an unbalanced current induced in the receiving coil. An overheat protection circuit indicates that the balun is abnormal when a temperature of the balun exceeds a temperature threshold. An imaging control unit stops imaging when the overheat protection circuit indicates an abnormality of the balun.

Abstract: A method and system for applying nuclear magnetic resonance (NMR) sequences to a substance are described herein. The method includes applying an NMR pulse sequence to the substance using a non-resonant transmitter circuit. The NMR pulse sequence includes a first pulse sequence segment applied at a first frequency to a first shell within the substance and a second pulse sequence segment applied at a second frequency to a second shell. The second pulse sequence segment is initiated before the first shell reaches thermal equilibrium. In some cases, the first pulse sequence segment and the second pulse sequence segment are interposed within each other. Such NMR pulse sequences, with multiple pulse sequence segments, can also be applied to different atomic nuclei.

Abstract: This invention relates to a system that adaptively compensates for subject motion in real-time in an imaging system. An object orientation marker (30), preferably a retro-grate reflector (RGR), is placed on the head or other body organ of interest of a patient (P) during a scan, such as an MRI scan. The marker (30) makes it possible to measure the six degrees of freedom (x, y, and z-translations, and pitch, yaw, and roll), or “pose”, required to track motion of the organ of interest. A detector, preferably a camera (40), observes the marker (30) and continuously extracts its pose. The pose from the camera (40) is sent to the scanner (120) via an RGR processing computer (50) and a scanner control and processing computer (100), allowing for continuous correction of scan planes and position (in real-time) for motion of the patient (P). This invention also provides for internal calibration and for co-registration over time of the scanner's and tracking system's reference frames to compensate for drift and other inaccuracies that may arise over time.

Abstract: A GRASE-type PROPELLER sequence called Steer-PROP is disclosed. This sequence exploits a serious of steer blips together with rewinding gradient pulse to traverse k-space. Steer-PROP improves the scan time by a factor of 3 or higher compared to FSE-PROPELLER, provides improved robustness to off-resonance effects compared to EPI-PROPELLER, and addresses a long-standing phase correction problem inherent to GRASE based sequences. Steer-PROP also enables intra-blade, inter-blade, and inter-shot phase errors to be separately determined and independently corrected.

Abstract translation: 公开了称为Steer-PROP的GRASE型PROPELLER序列。 该序列利用严重的转向抖动以及倒带梯度脉冲来遍历k空间。 与FSE-PROPELLER相比，Steer-PROP将扫描时间提高了3倍或更高，与EPI-PROPELLER相比，提供了非共振效应的改进的鲁棒性，并且解决了基于GRASE的序列固有的长期相位校正问题。 Steer-PROP还可以单独确定和独立地校正刀片内，刀片间和插补相位误差。

Abstract: Apparatus and methods provide a physiological status sensing device (40) for sensing a physiological status of a patient (4) and minimizing an amount of interference (78) generated during a resonance (MR) scan by a magnetic resonance (MR) system (8). The device (40) includes a first, active sensor (64) located to sense the physiological status and experience MR scan related interference and to generate a first signal (80) having a physiological status component (76) and an interference component (78). A second non-active sensor (70) is located closely adjacent to the first sensor (64) to experience substantially the same MR scan related interference (78) as the first sensor (64) and generate a second signal (82) having only the interference component (78). A circuit or processor (56, 84, 110, 116) subtractively combines the first (80) and second signals (82) to cancel the interference component (78).
