    • A medical probe kit and method of treating abnormal tissue within a patient is provided. The kit comprises a cannula having a shaft, a lumen extending through the cannula shaft, and a first ablation electrode disposed on the distal end of the cannula shaft. The cannula may have a handle mounted to the proximal end of the cannula shaft, and an optional fluid delivery port on the handle in fluid communication with the cannula lumen. The kit further comprises an ablation probe configured to be removably disposed within the delivery cannula lumen. The ablation probe has a shaft and a second ablation electrode disposed on a distal end of the probe shaft, wherein the first and second ablation electrodes are arranged in a bipolar configuration. Preferably, the ablation probe is slidable relative to the delivery cannula, whereby the distance between the first and second ablation electrodes can be adjusted. Thus, the delivery cannula can be used to interchangeably deliver the ablation probe and other medical elements, such as a biopsy needle, obturator, and chemotherapeutic agent.
    • 提供一种治疗患者体内的异常组织的医疗探针套件和方法。 套件包括具有轴的套管,延伸穿过套管轴的内腔和设置在套管轴的远端上的第一消融电极。 套管可以具有安装到套管轴的近端的手柄,以及手柄上与插管腔流体连通的任选的流体输送口。 该套件还包括构造成可移除地设置在输送插管腔内的消融探针。 消融探针具有设置在探针轴的远端上的轴和第二消融电极,其中第一和第二消融电极被布置成双极结构。 优选地,消融探针可相对于输送套管滑动,从而可以调节第一和第二消融电极之间的距离。 因此,输送插管可以用于可互换地递送消融探针和其它医疗元件,例如活检针,闭孔器和化学治疗剂。

    • An imaging optical system includes a subtelescope array, with at least two subtelescopes, each having a single entrance pupil and an exit light beam. Each subtelescope has an optical pointing axis, and the pointing axes for the subtelescopes are parallel. An imager forms an image from the exit light beams at an image surface, where there is a sensor such as a focal plane array. Preferably, a phase shifter array includes a phase shifter for each of the subtelescopes. The phase shifter array receives the exit light beam of each of the subtelescopes and has a capability to adjust the phase of at least one of the exit light beams. The imager receives the phase-shifted exit light beams.
    • 一种成像光学系统包括具有至少两个子幻影镜的每个具有单个入射光瞳和出射光束的子暗镜阵列。 每个子视角具有光学指向轴,子幻影的指向轴是平行的。 成像器从图像表面处的出射光束形成图像,其中存在诸如焦平面阵列的传感器。 优选地,移相器阵列包括用于每个子幻影镜的移相器。 移相器阵列接收每个子幻影镜的出射光束,并且具有调节至少一个出射光束的相位的能力。 成像器接收相移出射光束。
