Mpr

3D tomographic images are usually acquired in transaxial plane. Coronal and sagittal views are desirable in some cases for a better perception of the image. MPR slices the 3D volume in different planes than the plane in which it was acquired. The three orthogonal views, axial, coronal, and sagittal, can be depicted in 3D space to demonstrate their spatial relationship. Figure 6 shows the axial, coronal, and sagittal views of a brain study. The reformatted image can also be on any arbitrary oblique plane in the volume space to visualize structures not on the orthogonal planes. In some cases, a curved section can be defined to render a curvilinear object such as the spinal canal (22).
