摘要： A breast compression device is disclosed for use in a mammography system. A paddle support frame is provided which is slidably connected to a system arm of the mammography system. The paddle support frame is located between the x-ray tube and the detector of the mammography system. A compression paddle is pivotally connected within the support frame by a pivot connection. The pivot connection is located on a chest wall side of the support frame. The chest wall side is opposite the system arm. The compression paddle is substantially horizontal to the detector and is rotatable around the pivot connection. The compression paddle may include a breast portion which is substantially parallel to the detector and a chest wall portion which is substantially vertical to the detector. The compression paddle may also have a contoured shape where the chest wall portion is angled away from the system arm and the breast portion is contoured to mimic the contours of the breast.

摘要： The invention includes both systems and methods for tomosynthesis x-ray imaging. An x-ray source is moved at various positions in an arc around an object, e.g., a breast, to illuminate a stationary digital detector (or its equivalent) placed at an image plane behind the object. A digital image data processor collects data from the detector and a motion controller moves the source around the object. As the source moves along the arc, the detector generates, for a succession of points along the arc, a corresponding succession of image data sets, each set being representative of the intensity of x-rays incident on the detector for the then current position of the source. The image data processor is responsive to the image data sets to generate an output image signal representative of the x-ray absorption of points within the object region. The processor transforms the image plane data to a form corresponding to that which would have been generated had the x-ray source moved in a linear motion in a source plane parallel to the image plane, rather than an arc. The resultant image data thus corresponds in form to that produced by a conventional linear motion, e.g., Twinning-type, system, so that conventional techniques and equipment may be used to produce a final representation of the x-ray absorption of the object region.
摘要翻译：本发明包括用于层析合成X射线成像的系统和方法。 X射线源在围绕物体（例如乳房）的弧中的各个位置移动，以照亮放置在物体后面的图像平面上的固定数字检测器（或其等效物）。数字图像数据处理器从检测器收集数据，并且运动控制器围绕物体移动源。当源沿着弧线移动时，检测器对于沿着弧的一系列点产生对应的连续的图像数据集，每组都代表入射在检测器上的X射线的强度，用于当前的位置来源。图像数据处理器响应于图像数据组以产生表示对象区域内的点的x射线吸收的输出图像信号。处理器将图像平面数据转换成与X射线源平行于图像平面的源平面中的线性运动而不是弧形而产生的图像平面数据相对应的形式。所得到的图像数据因此对应于通过常规线性运动产生的图像数据，例如，Twinning型系统，使得常规技术和设备可以用于产生对象区域的x射线吸收的最终表示。

摘要： A separable double lumen endotracheal tube is disclosed having a first lumen and a second lumen and which are removably affixed together to allow the first lumen to be separated from the second lumen of the double lumen endotracheal tube and, if desired, to be subsequently affixed together again. Either lumen of the double lumen endotracheal tube can function alone for positive pressure ventilation, but normally the bronchial lumen will be removed from a patient and the tracheal lumen left in place to function alone to provide positive pressure ventilation as required by a patient. The double lumen endotracheal tube will, however, function to allow the bronchial lumen to remain in a patient subsequent to removal of the tracheal lumen as a matter of choice during a medical procedure.
