    • PROBLEM TO BE SOLVED: To more improve an efficiency for detecting an anatomical object by using an MSL in the detection of the 3D anatomical object.
      SOLUTION: As for an inputted medical image, a restricted search range is determined in accordance with a training volume. A position candidate is detected within the restricted search range by using a first classification member to be trained. In the training volume, a direction example is used to form a position-direction assumption from the position candidate. A position-direction candidate is detected from the position-direction assumption by using a second classification member to be trained. In the training volume, a similarity converting assumption is formed from the position-direction candidate in accordance with a scale example. Similarity converting candidates are detected from the similarity converting assumption by using a third classification member to be trained. In accordance with at least one of the similarity converting candidates, the 3D anatomical object is detected in a medical image volume.

    • 要解决的问题:通过在检测3D解剖体中使用MSL来更有效地提高检测解剖体的效率。

      解决方案:对于输入的医学图像,根据训练量确定受限搜索范围。 通过使用要训练的第一分类成员在受限搜索范围内检测候选位置。 在训练量中,使用方向例来从候选位置形成位置方向假设。 通过使用要训练的第二分类成员从位置方向假设检测位置方向候选。 在训练量中,根据比例示例从位置方向候补形成相似度转换假设。 通过使用要训练的第三分类成员从相似性转换假设检测相似度转换候选。 根据相似度转换候选中的至少一个,在医学图像体积中检测3D解剖对象。 版权所有(C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To measure the time difference between two events at high temporal resolution, and to reduce electromagnetic interference caused by the time measurement.
      SOLUTION: In this method, the time difference (T) between a first event (A) and a second event (B) is determined using a measurement signal evaluating unit (3) of a position measurement system. Position values are determined from an individual periodic signal or from a plurality of periodic signals x
      1 (t) and x
      2 (t), wherein a first position value ϕ
      A is determined using a measurement signal evaluation unit (3) when the first event (A) occurs, and a second position value ϕ
      B is determined using the measurement signal evaluation unit (3) when the second event (B) occurs. The time difference (T) is determined from the first and second position values ϕ
      A and ϕ
      B .

    • PROBLEM TO BE SOLVED: To provide a memory architecture with multilevel hierarchy structure having a plurality of external ports.
      SOLUTION: Multi-port memory architecture having a multilevel hierarchy typically has one-port memory cells in the lowermost hierarchical level. The memory blocks in the respectively higher hierarchical levels are each made up of memory blocks from the next lower hierarchical level. By the defined multi-port memory architecture with multilevel hierarchy, the required surface area on the chip is reduced. The memory blocks in the hierarchical levels can, depending on requirement, be disposed in a memory block matrix in a switching network, a banking technique arrangement, and so forth. Thus, depending on the desired application, the greatest possible freedom of design is provided. The multi-port memory architecture also has a circuit for handling access conflict.
