Exam 6.0.3


The Exam software uses the parameters related to the probe, as well as the B-TX and B-RX to automatically determine the geometry of the transducer grid. This is a deterministic process and does not involve any input from the user. The geometry of the screen grid as well as its respective location with respect to the transducer gird can be adjusted by the user. Microns Per Pixel (MPP) is the vertical and horizontal (physical) sizes of the display pixel in microns. The origin determines the vertical and horizontal coordinates of the center of the transducer grid in the display coordinates. For instance, when the horizontal size of the image is 640 pixels, a value of 320 for the first Origin parameter puts the center of the transducer grid in the center of the image, horizontally.

  • MPP
  • Origin

Since each pixel of the screen is processed by the scan conversion algorithm (its value is calculated based on the values of the pre scan conversion B-mode data) the software has the ability to perform such tasks as flipping and zooming in this step. The following parameters can be used for this purpose:

  • Initial Zoom
  • Image Flip
  • Zoom - User
  • Zoom Offset
