Display, Volume Rendering, and Surfaces

2-D and 3-D medical image display, 3-D surface generation, and volume rendering

Medical Imaging Toolbox™ provides tools to visualize 2-D and 3-D medical image data. Interactively display medical images in the Medical Image Labeler app, which automatically orients images in the anterior/posterior, left/right, and inferior/superior directions. Use volume rendering to visualize volumes in 3-D using display presets or customized display settings. You can also publish snapshot images and animations. Outside the app, you can generate and render surfaces for efficient display or 3-D printing or modeling applications. To get started, see Choose Approach for Medical Image Visualization.
