摘要： Disclosed is an image acquisition workstation including a multiple examination mode. In the multiple examination mode, a user selects an anatomical view or procedure prior to acquiring data. When the image data is acquired, the acquired data is stored in a data structure related to the selected procedure or anatomical view. As the user selects a procedure or anatomical view prior to each data acquisition, the image acquisitions can be acquired in any order.

摘要： A technique for selectively processing data from a digital detector includes determining an asymmetrical image area produced by orientation of a radiation source assembly. The assembly may include a radiation source and a collimator, which may be separately orientable. The image area is computed based upon the orientation of the radiation source assembly that projects a radiation beam towards an imaging plane. Image data from a detector within the imaging plane is selectively processed to improve computational efficiency. The system may also determine whether the image area falls within the imaging surface of the detector and inform an operator or inhibit an exposure if such is not the case.

摘要： Certain embodiments of the present invention provide for a system and method for assessing the accuracy of a surgical navigation system. The method may include acquiring an X-ray image that captures a surgical instrument. The method may also include segmenting the surgical instrument in the X-ray image. In an embodiment, the segmenting may be performed using edge detection or pattern recognition. The distance between the predicted location of the surgical instrument tip and the actual location of the surgical instrument tip may be computed. The distance between the predicted location of the surgical instrument tip and the actual location of the surgical instrument tip may be compared with a threshold value. If the distance between the predicted location of the surgical instrument tip and the actual location of the surgical instrument tip is greater than the threshold value, the user may be alerted.
