Summary
Software windows offer a flexible method for mapping Hounsfield numbers from CT scans to display image grey levels. This technique, demonstrated with examples, has been implemented on an EMI viewing console.
Area of Science:
- Medical Imaging
- Computer Science
Background:
- Computed Tomography (CT) scans generate images based on Hounsfield numbers.
- Displaying CT scan data requires mapping these numbers to visible grey levels.
Purpose of the Study:
- To introduce a flexible and general software method for mapping CT scan Hounsfield numbers to display grey levels.
- To demonstrate the implementation of this method on a specific viewing console.
Main Methods:
- Utilizing software windows to define arbitrary functions for Hounsfield number to grey level mapping.
- Illustrating the method with practical examples.
Main Results:
- The software window method provides a versatile approach for image display adjustments.
- Successful implementation on an EMI viewing console validates the method's practicality.
Conclusions:
- Software windows offer an effective and adaptable solution for visualizing CT scan data.
- The demonstrated implementation highlights the method's utility in medical imaging display systems.
