    • A system for three-dimensional tomosynthesis imaging of a target element is provided having an image acquisition element and a processor. The image acquisition element obtains a plurality of images of the target element from a plurality of angles and includes a radiation source that is positionable at a plurality of angles with respect to the target element and a radiation detector. The radiation detector is positioned so as to detect radiation emitted by the radiation source passing through the target element and determine a plurality of attenuation values for radiation passing through the target element to establish a radiation absorbance projection image of the target element for a particular radiation source angle. The processor is configured to apply an iterative reconstruction algorithm to the radiation absorbance projection images of the target element obtained from a plurality of radiation source angles to generate a three-dimensional reconstruction of the target element. The system can gain further accuracy where the iterative reconstruction algorithm is applied using cone-beam forward projection and back projection.
    • 提供了具有图像采集元件和处理器的目标元件的三维断层合成成像系统。 图像采集元件从多个角度获得目标元件的多个图像,并且包括可相对于目标元件以多个角度定位的辐射源和放射线检测器。 放射线检测器被定位成检测通过目标元件的辐射源发射的辐射,并确定通过目标元件的辐射的多个衰减值,以建立用于特定辐射源的目标元件的辐射吸收投影图像 角度。 处理器被配置为对从多个辐射源角度获得的目标元件的辐射吸收投影图像应用迭代重建算法,以产生目标元素的三维重建。 在使用锥束前向投影和反投影应用迭代重建算法的情况下,系统可以获得进一步的准确性。

    • An apparatus for protecting vehicles and products being loaded and moved by means of a forklift. By attaching the invention to the front of the forklift mast, the product, or pallet the product is on, is moved forward to the end of the fork lift tines so that they are not prtotruding from underneath the pallet thus preventing damage caused by the tines. The invention also prevents damage to the side of vehicle doors. Being made by a reaction injection molding, the invention is made of a hard rubber material that absorbs the impact of any contact made. The invention is also of a non skid material so the load will remain stabilized. The invention is movable to accomodate any size load.

    • A method for locating a lesion within a tissue mass, includes steps of measuring a selected parameter at two or more points in at least one path through the tissue mass, the measure of the selected parameter in a lesion being different from that in normal tissue. Also, apparatus for measuring a tissue parameter at two or more points in at least one path through the tissue mass includes an insertion needle, distally sharpened and made sufficiently rigid so that it can be inserted distal end foremost into the tissue mass along the path, and, insertible with the needle, a sensor capable of prodding a measure of the tissue parameter at a point in the tissue mass along the path. Where the parameter is selected as one that has a measure different in a lesion type, the apparatus can be used in carrying out the method, whereby a measure at a point in the tissue mass of the selected tissue parameter provided by the sensor indicates that the point is within a lesion. In an embodiment for measuring interstitial fluid pressure in the tissue mass, the sensor includes a tube slidably engageable within the lumen of the insertion needle; the sensor tube is closed at a distal end, and the walls of the sensor tube and the insertion needle are prodded distally with ports, positioned in relation to the respective distal ends such that when the sensor tube is engaged within the insertion tube lumen the ports can be substantially aligned to provide fluid communication between the lumen of the sensor tube and the tissue adjacent the ports; the sensor tube lumen contains a plurality of filaments, and is operationally connected to a pressure measurement deuce such that the pressure measurement deuce is responsive to fluid pressure within the sensor tube lumen.
    • 一种用于定位组织块内的损伤的方法,包括以下步骤:在至少一个穿过组织块的路径中的两个或多个点处测量所选择的参数,所述病变中所选参数的测量与正常组织中的不同。 此外,在穿过组织块的至少一条路径中的两个或更多个点处测量组织参数的装置包括:远端切削并制成足够刚性的插入针,使得其可以沿着路径最前端插入组织块, 并且能够与针一起插入能够沿着路径刺激组织块中的一点处的组织参数的测量的传感器。 如果参数被选择为具有在病变类型中不同的度量的参数,则可以使用该装置来执行该方法,由此由传感器提供的所选择的组织参数的组织块中的点处的度量指示: 点在病变内。 在用于测量组织块中的组织液压的实施例中,传感器包括可滑动地接合在插入针的内腔内的管; 传感器管在远端封闭,并且传感器管和插入针的壁通过端口向远端方向延伸,其位置相对于相应的远端,使得当传感器管接合在插入管腔内时,端口 可以基本上对准以提供传感器管的内腔和邻近端口的组织之间的流体连通; 传感器管腔包含多个细丝,并且可操作地连接到压力测量装置,使得压力测量装置响应于传感器管腔内的流体压力。
