Figure 1: An example of AnatomyBrowser for a brain data set. The cross-hair positions correspond to the same 3D point. Some of the structures are annotated on the 3D display. The sagittal slice is slightly zoomed in.

Figure 4: Atlas to patient initial alignment. Even after successful execution of the registration algorithm there is a remnant of misalignment which is due to difference in shape.

Figure 1: Fifty-two-year-old patient treated for a high-grade glioma (glioblastoma multiforme) with resection and local high-dose radiosurgery approximately 2 years before the dynamic imaging study. (a) Dynamic MR image in the coronal plane obtained 36 seconds after gadolinium injection shows a focus of early enhancement in the right inferior temporal lobe (arrows).(b) Dynamic MR image in the coronal plane 1cm posterior to a obtained 39 seconds after injection shows no definite enhancement of the brain at a time when the venous sinuses are enhancing (arrows). (c) T1-weighted coronal image through the plane of a shows enhancement in the right temporal lobe, representing either recurrent tumor or radiation change. Numbers refer to regions from which graphic data were obtained (see Fig. 2). (a) T1-weighted coronal image through the plane of b shows non-specific enhancement in the right inferior parietal lobe. Numbers refer to regions from which graphic data were obtained (see Figure 2).

Figure 10: A, Three orthogonal spoiled gradient-recalled echo in the steady state 3D MR images (35/5/1; flip angle= 45°; FOV=24; thickness=1.5 mm; matrix=256x192) accompanied by 3D coronal reconstruction from MR data (acquired before surgery) (upper left) show location of right lateral nasal wall (crosshair and yellow arrow). B, Same MR images as in A displayed with virtual endoscopic image generated from preprocedural MR data localizing right lateral nasal wall. C, Axial, sagittal, and coronal near real-time FSE T1-weighted MR images (400/26/1; FOV=20; echo train=4; matrix =256x128) show localization of right lateral nasal wall.
