Online OsiriX Documentation/3-D reconstructions
OsiriX supports three 3D reconstruction modules:
1) Maximum Intensity Projection (MIP)
3D MIP Reconstruction
This reconstruction uses a ‘ray-tracing’ technique to identify which pixel has the maximum intensity on each ray. This technique is useful for contrast MRIs or CTs, and bone CTs.
2) Volume Rendering
3D Volume Rendering
This reconstruction uses a ‘ray-tracing’ technique to apply a transparency/opacity to each pixel depending on their position and their intensity. This technique produces nice images of soft tissues for MRI and CT. It is actually the most used 3D technique and will produce the nicest images in many situations.
3) Surface Rendering
3D Surface Rendering
This reconstruction produces surfaces that are based on an “iso-contour” defined by the user. This technique is useful for virtual endoscopy and bone CTs. The user can define two different surfaces to render.
