摘要： An instrument guide is described for mounting an invasive instrument such as a biopsy needle to an imaging probe, controlling its position, monitoring its position, and/or predictively displaying its position on a user display of the medical imaging system. A plurality of substantially rigid segments are hingeably connected to the probe, to an instrument handle, and to each other such that movement of the biopsy needle is restricted to within the imaged plane. However, substantial freedom of movement within the imaged plane is provided such that the instrument may be inserted into the patient over a wide range of angles. In one preferred embodiment, angle detectors are provided at each segment intersection and measurements provided for computing and displaying the instrument position and orientation on the user display. The instrument guide/position monitor is preferably made with low-cost components such that it is disposable after a single use. A predictive user display is provided in which the throw of a spring-loaded instrument is shown on the user display, the throw corresponding to the space that the instrument will occupy after a spring trigger is activated.

摘要： A method, system, and computer program product for providing textual ultrasound probe position information corresponding to an ultrasound image of a target is described. Based on a user's graphical manipulations of a probe icon relative to a breast icon, a text sequence corresponding to the user's estimate of the position of an ultrasound probe is automatically generated. User error and fatigue are reduced because manual keying of the probe position text sequence is no longer required, and the resulting outputs are standardized in format and therefore more amenable to archiving and electronic analysis. In one preferred embodiment, the user is permitted to select a snapping mode of operation in which the probe icon is snapped to align with a major direction of a preselected coordinate system, further enhancing ease-of-use and reducing user fatigue.

摘要翻译： 描述了用于提供与目标的超声波图像相对应的文本超声探针位置信息的方法，系统和计算机程序产品。 基于用户相对于乳房图标的探针图标的图形操作，自动生成与用户对超声波探头的位置的估计相对应的文本序列。 用户错误和疲劳减少，因为不再需要手动键入探针位置文本序列，并且所得到的输出格式被标准化，因此更适合归档和电子分析。 在一个优选实施例中，允许用户选择捕捉操作模式，其中探针图标被卡扣以与预选坐标系的主要方向对齐，进一步增强易用性并减少用户疲劳。
