GetMinAndMax(Single,Single,Single,Boolean) Method

In This Topic

Find the maximum and minimum pixel data values in the pixel data

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Sub GetMinAndMax( _
   ByRef Min As System.Single, _
   ByRef Max As System.Single, _
   ByVal Centile As System.Single, _
   ByVal Scale As System.Boolean _
)

public void GetMinAndMax( 
   out System.float Min,
   out System.float Max,
   System.float Centile,
   System.bool Scale
)

Parameters

Min: The minimum value found
Max: The maximum value found
Centile: Proportion of extreme values to ignore
Scale: Whether to apply scaling/modality lookup table transformation

Remarks

Pixel padding values are ignored

If Scale is false, then the values returned are "raw" values before application of rescaling or modality lookup tables

If Scale is true, then the values returned are transformed using the modality slope and intercept or modality lookup tables as appropriate to the image

If it is necessray to use separate control for the 2 scaling methods, then the GetMinAndMax(Single,Single,Single,Boolean,Boolean) override may be used instead.

Example

DicomDataSet ds = new DicomDataSet("Dataset.dcm");
float min, max;
float centile = 0.01f;
bool applyRescaling = true;
                    
ds.GetMinAndMax(out min, out max, centile, applyRescaling);
Console.WriteLine($"Scaled Min: {min}, Scaled Max: {max}");

Requirements

Target Platforms: .NET CLR 4.8 or higher
