The attached projects show how to implement an interactive tool capable of displaying properly translated extended grayscale value and RGB value on mouse click on an image. It will display signed CT value (Hounsfield in units) and X-Ray values (Optical Density units) assuming the image already went through modality transformation or was normalized.
The tool accounts for following:
- All allocated bits are not used for storing image data (e.g. high bit is 11 and allocated bit is 16)
- Signed bit is not the bit allcated-1. (this is the case for most CT images)
- Non zero low bit that causes incorrect (higher) interpretation of stored pixel values.
The projects are in
Visual Studio 2008 - x86 and x64 in both C# and VB.NET
Visual Studio 2010 - x86 and x64 in both C# and VB.NET
Note: You will need to copy the project to either [LEADTOOLS17]\Examples\Dotnet\CS or [LEADTOOLS17]\Examples\Dotnet\VB to be able to compile and run.
