  Open
   The Open Command is used to open an image (or images) to manipulate in RadPix. In addition to DICOM images, RadPix can open and work with many other common image types, including JPEG, GIF, TIFF, PNG, BMP (see supported image types). RadPix can also open unknown/raw images. If the program is unable to determine the type of image, the Open Raw Image Dialog will appear to let you specify parameters for the image

Note that the ROI, Window/Level and Measure Tools only work with DICOM and Raw Image formats.

 

Dialog Fields

This is the Standard Windows Open File Dialog.  The buttons at the top right of the screen are

  •   move up a directory level
  •   create new directory
  •   list directory
  •   details directory.

Notes

  • Open multiple sequential images by selecting the first image, holding down the shift key, then selecting the last image to open, then click the Open button.
  • Open multiple non-sequential images by holding down the control key and selecting individual images, then click the Open button.
  • You can right-click on any file and a context sensitive menu will appear that will let you do some file manipulation activites, including [depending on your system configuration]
    • Delete File
    • Rename File

Open Raw Image
   If RadPix is unable to determine the type of image when it tries to open it, this dialog will appear. This should allow you to open nearly any type of image (including raw byte data), if you know how the data is organized.

 
Dialog Fields
Header Length This is the length [in bytes] of the image header
Width This is the width [in pixels] of the image. Note that the number of bytes per row equals the width times the pixel depth divided by the pixel depth.
Height This is the height [in pixels] of the image.
Pixel Depth This is the number of bits used to represent each pixel
Byte Order If the pixel depth is greater than 8, the bytes can be in different orders in the file, depending on whether the image was created on a Windows [Intel - Little Endian] machine or a Mac [Big Endian] machine. If you have any questions please see your systems administrator regarding byte order. If the loaded image doesn't look right, try reversing the byte order.
Window Computation RadPix computes a starting Level for a raw image equal to the mean of the pixel values in the image. When computing a starting Window, it can use either the maximum pixel value minus the minimum pixel value, or a number equal to plus/minus 3 standard deviations from the mean.
