    • Apparatus for obtaining in-vivo nuclear magnetic resonance data from a moving joint of a patient for imaging or spectroscopic purposes is shown which includes a support (10) for support of the patient's hand and lower arm (12). Support (10) includes a stationary section (20) and a pivotally movable section (22) which is oscillated by motor (32). A pivot shaft (26) supports member (22) for pivotal movement in the direction of arrow (30) about the shaft axis (28). Straps (14) and (16) attach the patient's hand and forearm to the respective moving and stationary sections of the support whereby the patient's wrist joint is oscillated along a predetermined path during operation of motor (32). A timing cylinder (40) with timing marks thereon is attached to shaft (26), for generation of master timing pulses by photocell (44) responsive to the timing marks through fiber optic member (42). Nuclear magnetic resonance apparatus of conventional design generates magnetic fields within region (52) at the patient's wrist, and detects nuclear magnetic signals produced by the magnetic fields. Master timing pulses control operation of the magnetic resonance apparatus during oscillation of the wrist joint for production of imaging or spectroscopic signals at different points along the path of wrist movement. For operation in the imaging mode, a motion picture display of the moving wrist joint is provided at display (78). In the spectroscopy operation mode, spectrum data is displayed at display (78).
    • 示出了用于从用于成像或分光学目的的患者的移动关节获得体内核磁共振数据的装置,其包括用于支撑患者的手和下臂(12)的支撑件(10)。 支撑件(10)包括固定部分(20)和由马达(32)摆动的枢转运动部分(22)。 枢轴(26)支撑构件(22),用于围绕轴线(28)沿箭头(30)的方向枢转运动。 肩带(14)和(16)将患者的手和前臂附接到支撑件的相应移动和静止部分,由此在电动机(32)的操作期间患者的腕关节沿预定路径摆动。 其上具有定时标记的定时滚筒(40)附接到轴(26),以响应于通过光纤构件(42)的定时标记由光电池(44)产生主定时脉冲。 常规设计的核磁共振装置在患者腕部的区域(52)内产生磁场,并且检测由磁场产生的核磁信号。 主定时脉冲控制磁共振装置在腕关节振荡期间的操作,用于在手腕运动路径的不同点产生成像或分光信号。 为了在成像模式中进行操作,在显示器(78)处设置有运动的腕关节的运动图像显示。 在光谱操作模式下,在显示器(78)显示光谱数据。
