Select Process
Define process
# n to be used as one of the vectors when
calculating a filter. If a new process is
being defined, the number of processes is increased by 1. To start
over, press Clear Processes.

Select Roi
to use a region of interest drawn on the current image of the selected
browser or from a region of interest file selected in the
File Load dialog.
The pixels in the region of interest will be used to calculate an average
vector to be used as process # n. If
using a region of interest that was drawn, it will automatically be saved
using the process name as the extension.
If the the region of interest is from a file, the extension will be
displayed in the process name.
 |
Select 1, 2, 3,
or 4 in B for the browser that contains the region of
interest if using a region of interest that was drawn.
|
 |
Enter or display a name, of the anatomical feature, in
Process Name. Press Enter to
Select Process, without using the Select
Process button.
Note
The default is rn, where n is the
process number. The name will be highlighted for overwriting.
|
|
 |
Select
Pixel to use each pixel vector as process
# n when calculating a
filter.
|
 |
Select Constant
to use a constant vector as process # n when
calculating a filter.
|
|
 |
Process Number
|
 |
Select or
display n for the P to define/redefine process # n. The
process name will also be displayed, if it
exits.
|
 |
Subtract
Background
Enter a
multiplication factor in -background. The background vector
will be mutliplied by this factor and then subtracted from process
# n.
 |
Select
Background
Press Select
Background to use the a region of interest drawn on the current image of
the selected browser or from a region of interest file selected in the
File Load dialog as the
background process. The pixels in the region of interest will be used
to calculate an average vector to be used as the background process.

Filter Image
Press Filter
Image to calculate the selected filter, using the
processes that are currently defined. If one of the processes is the
pixel vector, a filter will be calculated for each
pixel, otherwise a single filter is calculated. The calculated
filter(s) are then applied to the selected images.
 |
Filter Type
 |
Select Gram-Schmidt
to use a gram-schmidt filter.
|
 |
Select Eigen
to use eigen analysis to calculate the filter. (reference)
|
 |
Select Gram-Schmidt-Rotation to use a gram-schmidt filter with
rotation.
|
 |
Select Gram-Schmidt-Constant to use a gram-schmidt filter with a
constant.
|
 |
Select Matched w/o
Variance to use a matched filter without variance.
|
 |
Select Matched w
Variance to use a matched filter with variance.
|
 |
Select Correlation to use a correlation filter.
|
 |
Select Average to use an averaging filter (1 / # images).
|
 |
Select Energy
Difference to use an energy difference filter.
|
 |
Select Difference of
Energy to use a difference of energy filter.
|
 |
Select Cross Product to use a cross-product filter.
|
 |
Select Difference to use a difference filter. (reference)
|
 |
Select D-U1,U2 to use a gram-schmidt filter with first process being
redefined as process #1 - process #2. Process # 3 now becomes the
second process.
|
 |
Select D-U2,U1to use a gram-schmidt filter with first process being
redefined as process #1 - process #3. Process # 2 remains the second
process.
|
 |
Select Max-Min CNR to use a maximum-minimum contrast to noise ratio
filter. (reference)
|
 |
Select Feature
Suppression to use a feature suppression filter.
|
 |
Select (R inverse) * d to use a filter equal to the inverse of the
covariance matrix of the second process multiplied by the first process.
|
 |
Select File to use a previously saved filter. Either a
signature (.sig) or report (.rep) file can be selected.
|
|
 |
Normalize
Select
Normalize to normalize the filter vector.
|
 |
Smooth
Select Smooth
to apply a butterworth smooth to the filter vector.
 |
Enter a value
of the Butterworth filter in Order.
|
 |
Enter the
cutoff frequency for the Butterworth filter in Cutoff.
|
|
 |
Output
 |
Select Single Process
to create a filtered image with the first process as the desired process.
|
 |
Selected All Processes
to create multiple filtered images, using each process as a desired process.
|
 |
Select A-Ortho
to create a filtered image for each process as the desired process, with the
remaining processes as undesired. An image of the amplitude of the
orthogonal vectors is also created.
|
 |
Select A-Corr
to create a filtered image for each process as the desired process, with
the remaining processes as undesired. An image of the correlation of
the orthogonal vectors is also created.
|
 |
Select A-Vec
to create a filtered image for each process as the desired process, with the
remaining processes as undesired. The images, representing the
orthogonal vectors, will also be created.
