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.
