The buttons in the first row allow defining the orientation of the displayed images.
Note: The direction z, y or x indicates the normal to the plane shown. The z-plane denotes the orientation of the images after loading (assuming axial slices). The y-, x- and orthogonal buttons are not active if the study is planar only and can thus not be resliced in other directions.
The plane orientation can rapidly be switched by first activating an image (click into image), and then entering
The second and third rows allow configuring the number of images shown concurrently. If the radio button in the second row is enabled, a dedicated row x column layout can be defined for the different orientations. This is particularly helpful for a whole-body study where the coverage in z is much larger than in the other directions.
Otherwise, if the radio button of the third row is enabled, the same layout is applied for all orientations and the arrangements are accessible through the selection
Keyboard shortcuts allow to quickly switch arrangements. After activating the image enter
To change from a RxN arrangement to 1x1 just click on the image to be enlarged holding down the CTRL key. To change back to the multi-image layout just CTRL+ click once more.
The radio button in the fourth row is only applicable for image tiling with dynamic studies. If the radio button is in the position of
Image reorientation operations such as mirroring and rotations can be done using the buttons in the bottom row.
If the display is in the orthogonal viewing mode, first activate the appropriate plane by clicking onto the corresponding image (holding down the CTRL key avoids new reslicing), and then activate the appropriate button. For data with enough information about patient positioning PMOD will keep track of patient orientation and update the annotations accordingly.
Sagittal images can be shown in two ways, either horizontally (laying on back), or vertically (standing). The user can set his preference by means of the two buttons on the right of the pane.
If the orthogonal layout is selected, three quadrants show the orthogonal slice images intersecting at the point indicated by the cross centered in the blue slice indication lines. As soon as the user clicks into an image, the images are updated by the slices intersecting at that new point.
The fourth quadrant is available for different information. It can be configured by activating the button located in the upper left corner of that quadrant, indicated in red in the screen capture above. A dialog appears
which lets choose between an Empty quadrant, a Locator display showing the slices location schematically, and a MIP (Maximum Intensity projection). Note that there is a marker in the MIP image, which indicates the current slices intersection. It can be moved, and the slice images will follow. This function may be helpful to track vessels showing up highlighted in the MIP.
