摘要： A method and system for guiding imaging reading for colon screening includes scrolling through a succession of two dimensional (2D) cross-sectional images of a colon in respective image planes. A point of intersection with a current image plane with the centerline of the colon is marked in a first color in the current cross-sectional image. As the scrolling proceeds and a new current cross-sectional image in a respective image plane is observed. a new point of intersection is marked in the current cross-sectional image in the first color and the prior point of intersection is projected onto the new current cross-sectional image and marked in a second color.

摘要： A combination radiography and fluoroscopy system includes in one embodiment a radiography radiation generator and radiography radiation receiver, a fluoroscopy radiation generator and fluoroscopy radiation receiver, and a single computer system connected to receive signals from the radiography radiation receiver and fluoroscopy radiation receiver. The single computer system includes signal processing paths for the radiography signal and for the fluoroscopy signal wherein some processes or modules are common between the paths and some are path specific. The path specific processes are preferably connected in parallel. Common controls and a common interface are provided to the monitor connected to the computer system. An alternative uses a single radiation receiver for both radiography and fluoroscopy, along with the single computer system Another alternative provides for separate computers for signal processing of the radiography and fluoroscopy signals, the two computers running substantially identical signal processing programs.

摘要： A method and apparatus for guiding image reading for colon screening, includes calculating a centerline for a colon; scrolling through a succession of two dimensional (2D) cross-sectional images of a colon in respective image planes, such that a current image plane includes a respective current focus point formed by an intersection of the centerline with the current image plane. The method further includes performing a three-dimensional (3D) region growing process for growing a region of a suitable given thickness around a current seed point in a current image plane, the current seed point being at the respective current focus point in the current image plane, such that the region growing “floods” folds within a prescribed distance from the current seed point such that part of the region intersects the current image plane. Portions of the region intersecting the current image plane that meets at least one of conditions (A) and (B) are removed from consideration where: condition (A) includes the region intersecting the given current image plane containing a further connected component not containing the current seed point, and containing a further intersection of the image plane with the centerline other than the current seed point, and condition (B) includes the further connected component exhibiting a larger area than that exhibited by a connected component containing the current seed point; and marking remaining portions of the region intersecting the current image plane, not removed from consideration, as seen areas.

摘要： With a method for controlling the dose or dose rate when recording x-ray images by means of a detector comprising image elements which record a plurality of dose data values, an actual value is determined for the dose or dose rate from the totality of the data values recorded by the image elements of a predetermined image segment, said actual value being compared with a predetermined target value in order to control the dose or dose rate when recording a further x-ray image. In accordance with the invention, the actual value is determined such that on the basis of a frequency distribution of the dose data values of the image elements assigned to the dominant, a p-quantile is determined, and that the dose data value assigned to the p-quantile is used to determine the actual value.

摘要： A system and method for creating a panoramic projection of a volumetric image of an object is disclosed. A virtual camera is placed in a center of a cubic space within the object. Images obtained from the camera are projected onto a single plane. A front image is mapped in a window at a center of the plane. A left, right, top and bottom image of the cubic space are mapped around the rectangular window such that the left, right, top and bottom images form a continuous image surrounding the rectangular window.
