    • Facilitating viewer comparison of a plurality of medical images of at least one body part on a softcopy review workstation is described. First and second medical images are displayed such that the second medical image appears as a spatially registered underlay to the first medical image exposed through an aperture therein. The aperture comprises at least one edge that is viewer-manipulable in a back-and-forth manner so that the first and second medical images can be visually compared with minimal eye movement. For a temporal comparison embodiment, the first and second medical images comprise identical views of the same body part acquired at different times. For a cross-modality comparison embodiment, the first and second medical images are acquired substantially concurrently, or at different times, using different medical imaging modalities. For a bilateral comparison embodiment, the first and second images are corresponding views of two laterally corresponding body parts.
    • 描述了在软拷贝检查工作站上促进对至少一个身体部位的多个医学图像的观看者比较。 显示第一和第二医疗图像,使得第二医疗图像作为空间注册的底层显示出通过其中的孔暴露的第一医疗图像。 所述孔包括至少一个能够以往复方式观察者操纵的边缘,使得可以在视觉上比较第一和第二医学图像与最小的眼睛运动。 对于时间比较实施例,第一和第二医学图像包括在不同时间获取的相同身体部位的相同视图。 对于交叉模态比较实施例,使用不同的医学成像模式基本同时或不同时间获取第一和第二医学图像。 对于双向比较实施例,第一和第二图像是两个横向对应的身体部分的对应视图。

    • In order to provide a high sensitivity variable gain amplifier, there is provided a structure in which at least one path comprising at least a stage of the voltage-input/voltage-output amplifier+ a stage of voltage-input/current-output amplifier and a path comprising a stage of the voltage-input/current-output amplifier are connected in parallel between the input terminal and output terminal or, a structure in which a plurality of paths each comprising at least a stage of voltage-input/voltage-output amplifier+a stage of voltage-input/current-output amplifier are connected in parallel between the input terminal and output terminal. A gain is switched by selecting and operating any one of paths. When any one path is selected, an input impedance viewed from the input terminal is suppressed almost not to change or an output impedance viewed from the output terminal is suppressed almost not to change. Thereby, a high sensitivity wireless receiver can be realized.
    • 为了提供高灵敏度可变增益放大器,提供了一种结构,其中至少一个路径包括电压输入/电压 - 输出放大器的至少一个级+电压输入/电流输出放大器的级和 包括电压输入/电流输出放大器的级的路径并联连接在输入端子和输出端子之间,或者其结构中,多个通路各自包括至少一级的电压输入/电压输出放大器 电压输入/电流输出放大器的一级在输入端子和输出端子之间并联连接。 通过选择和操作任何路径来切换增益。 当选择任何一个路径时,抑制从输入端子观察的输入阻抗几乎不变化,或者抑制从输出端子观察的输出阻抗几乎不改变。 因此,可以实现高灵敏度的无线接收器。
