Figure 1: Delineation of the planum temporale and Heschl’s gyrus regions of interest in (A) coronal, (B) sagittal, and (C) axial images. Heschl’s gyrus is indicated by black arrows and the planum temporale by white arrows. D, Three-dimensional reconstruction of temporal lobes showing the outlines of the planum temporale (white arrows) and of Heschl’s gyrus (black arrows).

Figure 6 a: A 128 3 128 segmented axial brain image used to define desired ventricular-shaped profile. b: Virtual excitation profile of a ventricular shape obtained by summing the experimental results from 16 interleaved excitations.

Figure 4: AnatomyBrowser user-end interface. An example of the interface for the 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 1: Schematic of image reconstruction and scalp localization. An oblique coronal plane was reformatted with multiplanar reconstruction algorithms. The projected point of the lesion (T), ipsilateral external auditory meatus (E), sagittal suture on this plane (S), and the bregma (B) were identified. Then the distance along the scalp of TS, TE and BS were measured on the MR console.

Figure 1: Frontal view of the surface models of both hips in neutral position. The left hip is affected by SCFE. The left femoral head (LFH) is displaced posterior and slightly inferior. The right femoral head (RFH) shows a normal geometry.

Figure 1: [Left] Bur hole approximately 100 mm in diameter was made to expose the brain of a pig (male, 48.5 kg, 100 days old). [Right] A specially developed acrylic frame with a clay weight was fixed to the MRI head coil, which also rigidly holds the pig's head.
