'''Note''': Consumer file formats, such as jpg, png, and tiff are not well suited for 3D medical image storage due to the following serious limitations:
 
−
 
−
* Storage is often limited to bit depth of 8 bits per channel: this causes significant data loss, especially for CT images.
 
−
* No standard way of storing essential metadata: slice spacing, image position, orientation, etc. must be guessed by the user and provided to the software that imports the images.
 
−
* No standard way of indicating slice order: data may be easily get corrupted due to incorrectly ordered or missing frames.
