Optimized algorithms for displaying 16-bit gray scale images on 8-bit computer graphic systems

Area of Science:

• Medical Imaging
• Computer Graphics
• Image Processing

Background:

• Medical gray scale images are typically stored as 16-bit integers per pixel.
• Most personal computers utilize 8-bit graphic display hardware.
• A discrepancy exists between medical image data depth and standard display capabilities.

Purpose of the Study:

• To develop and present algorithms for rapid 16-bit to 8-bit image data transformation.
• To enable the display of medical gray scale images on standard personal computers.
• To facilitate the use of personal computers as low-end medical imaging workstations.

Main Methods:

• Development of specialized algorithms for 16-bit to 8-bit image data remapping.
• Implementation of computer code for efficient image data transformation.
• Testing algorithms on personal computers with performance comparable to a Macintosh II.

Main Results:

• Algorithms achieve very rapid 16-bit to 8-bit image data transformation.
• Successfully remapped 16-bit medical gray scale images to 8-bit.
• Demonstrated the feasibility of using personal computers for medical image display.

Conclusions:

• The presented algorithms enable efficient display of medical images on standard personal computers.
• Personal computers can function as low-end Picture Archiving and Communication Systems (PACS) or workstations.
• This technology bridges the gap between medical imaging data and consumer-grade hardware.
