摘要： The application relates to a system (1) for determination of an orientation (14) of a biomedical stimulation device (2) in respect to an object (20). The system comprises the first biomedical stimulation device (2) comprising at least two stimulator for elements (4A;4C) and a generator (22) arranged for feeding the stimulator elements (4A;4C) with time-varying electric signals (6A;6C), wherein the time-varying electric signals (6A;6C) differ by a predetermined phase. The system further comprises a sensor device (10) with a known relative position (X;α) with respect to the first biomedical stimulation device (2), arranged for sensing a sensing signal (8) from the stimulator elements (4A;4C), wherein the sensing signal (8) is originated from the time-varying electric signals (6A;6C) from the stimulator elements (4A;4C) and a processor device (12) arranged for determining the orientation (14) of the first biomedical stimulation device (2) based on a sensed phase of the sensing signal (8), phases of the time-varying signals (6A;6C) and the known relative position (X;α). Said system accurately determines the orientation, i.e. angular position, of the biomedical stimulation device in respect to the object. The orientation is also accurately determined when the biomedical stimulation device is implanted in the object. Such a system is relatively cheap. The application also relates to a method for determination of an orientation (14) of a first biomedical stimulation device (2) in respect to an object (20).
摘要翻译：本申请涉及一种用于确定生物医学刺激装置（2）相对于物体（20）的取向（14）的系统（1）。该系统包括第一生物医学刺激装置（2），其包括用于元件（4A; 4C）的至少两个刺激器和布置成用于将刺激元件（4A; 4C）馈送到时变电信号（6A; 6C）的发生器），其中所述时变电信号（6A; 6C）相差预定相位。所述系统还包括相对于所述第一生物医学刺激装置（2）具有已知相对位置（X;α）的传感器装置（10），所述相对位置被设置用于从所述刺激器元件（4A; 4C）感测感测信号（8），其中所述感测信号（8）源自所述刺激器元件（4A; 4C）的时变电信号（6A; 6C）和布置成用于确定所述第一生物医学的方向（14）的处理器装置（12）基于感测信号（8）的感测相位，时变信号（6A; 6C）的相位和已知的相对位置（X;α）的刺激装置（2）。所述系统精确地确定生物医学刺激装置相对于物体的取向，即角位置。当将生物医学刺激装置植入物体时也准确地确定取向。这样的系统相对便宜。本申请还涉及用于确定第一生物医学刺激装置（2）相对于物体（20）的取向（14）的方法。
