|The MPR window doesn’t show the source data, it shows 3D structure slices. That is why tweening errors may occur|
|As the images in mIP, MIP, and AIP modes are the results of original images processing, tweening errors may occur. The measurements performed in these modes may be erroneous|
|The measurement accuracy is up to one screen pixel. As a screen pixel is smaller than a source image pixel, the true linear measurement accuracy is up to one source image pixel. Errors may also occur in density measurements. The most accurate measurements are performed with bilinear interpolation (see Section 2.4)|
|The MPR mode is not meant to be used for PET studies, use the specialized module (see Section 8).|
The measurements are conducted in the same way as for flat images (Section 2.15).
Additionally, the 3D Polygonal ruler tool is available in the MPR window. For details on how to work with this tool, see Section 3.9.2.
