Dialog Items

bullet

Image Size Zoom

Select the amount to zoom spectroscopy images to a suitable size for viewing on other image displays.

bullet

Select 1 for spectroscopy image size to match the spectra dimensions.
bullet

Select 2 for spectroscopy image size to be twice the spectra dimensions.
bullet

Select 4 for spectroscopy image size to be 4 times the spectra dimensions.
bullet

Select 8 for spectroscopy image size to be 8 times the spectra dimensions.
bullet

Select 16 for spectroscopy image size to be 16 times the spectra dimensions.
bullet

Analyze->Create Dummy Image

Select Create Dummy Image to create a blank localizer image for the purpose of loading raw spectroscopy data that does not have localizer images.  Dicom header information will be filled in by loading a GE LX spectrosocpy P-file.
bullet

Analyze->Combine (Loc + Spect)

Select Combine (Loc + Spect) to combine the peak images (result images from running Batch Analyze) with the original localizer image.  The tagged region of interest created when running Susceptibility will be used to determine which pixels to use from each image.

Note

The images needs to be the same size, use Image Size Zoom before running Batch Analyze so that the peak images will be the same size as the localizer image.
bullet

Print->Save Histogram

Select Save Histogram to save the displayed histogram as a Dicom Image.

Note

Make sure the histogram is not covered by any other windows before selecting this option.  A snapshot will be taken of the histogram and then converted to a Dicom image file.  The console will beep when the image has been saved.
bullet

Print->Screen Save

Select Screen Save to save the Display Image, with region of interest, annotation, and graticule as a Dicom Image.  The Image Selection dialog will come up for selection of the Display Window.

Note

Make sure the Display Image is not covered by any other windows before selecting this option.  A snapshot will be taken of the Display Image and then converted to a Dicom file.  The console will beep when the image has been saved.
bullet

Ok

Press Ok to activate the current spectroscopic processing.
