    • An alignment guide comprises a guide block locator having surfaces for engaging a prepared femur and establishing a specific position relative to an intercondylar slot in the femur. The guide block locator contains an aperture for directing a guide block to the specific position. The guide block includes a leg that can be driven into the femur to hold the guide block in place. The guide block is adapted to precisely engage the cam box of a femoral implant. Upon removal of the guide block locator, the femoral implant can be positioned over the guide block where the cam box will engage the guide block before the anterior and posterior flanges of the implant grip the anterior and posterior surfaces of the femur thereby providing proper alignment of the femur and implant.

    • A simplified method for rotating a digital image through a small angle without the need for interpolation is described. The image is divided into small, square blocks, arranged in horizontal rows where each block is exactly to the left or right of the other blocks in the row, and into columns where each block in the column is offset to the right by one pixel with respect to the next higher block. The rotation is then accomplished by moving the lower rows to the left so that the columns are exactly vertical, and by moving the rightmost columns in a downward direction so that each block is one pixel below the block to its left. The result is a rotation of the image through a small angle. There is a considerable simplification gained from not rotating the data within each block which results in a slight distortion of the image, but for small angles, this is not noticeable.
    • 描述了通过小角度旋转数字图像而不需要插值的简化方法。 图像被分成小的方块,排列成水平行,其中每个块恰好在行中的其他块的左侧或右侧,并且被列到列中的每个块向右偏移一个像素的列, 尊重下一个更高的块。 然后通过将下行移动到左侧使得列完全垂直,并且通过沿向下方向移动最右边的列使得每个块在其左侧的块下方一个像素来实现旋转。 结果是图像以小角度旋转。 通过不旋转每个块内的数据可以获得相当大的简化,这导致图像的轻微失真,但是对于小角度,这是不明显的。
