Detailed Description

Read SCANCO ISQ and AIM medical image files.

This class reads ISQ and AIM files, which are used for high-resolution computed tomography. The information that it provides uses different units as compared to the original files: all distances are given in millimeters (instead of micrometers), times are given in milliseconds (instead of microseconds), voltage and current given in kV and mA (instead of volts and microamps). If the scanner was calibrated, then the data values can be converted to calibrated units. To convert to linear attenuation coefficients [cm^-1], simply divide the data values by the MuScaling. To convert to density values, multiply the data values by the RescaleSlope and add the RescaleIntercept. To convert to Hounsfield units, multiply by 1000/(MuScaling*MuWater) and subtract 1000.

Created at the Calgary Image Processing and Analysis Centre (CIPAC).

Member Function Documentation

◆ CheckVersion()

static int vtkScancoCTReader::CheckVersion ( const char header[16] )

staticprotected

Check the file header to see what type of file it is.

Return values are: 0 if unrecognized, 1 if ISQ/RAD, 2 if AIM 020, 3 if AIM 030.

◆ GetRescaleSlope()

double vtkScancoCTReader::GetRescaleSlope ( )

inline

Get the slope and intercept for rescaling the scalar values.

These values allow calibration of the data to real values. Use the equation v = u*RescaleSlope + RescaleIntercept.

◆ IsA()

virtual vtkTypeBool vtkScancoCTReader::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageReader2.

◆ StripString()

static void vtkScancoCTReader::StripString	(	char *	dest,
		const char *	source,
		size_t	l
	)

staticprotected

Strip a string by removing trailing whitespace.

The dest must have a size of at least l+1.

The documentation for this class was generated from the following file:

vtkScancoCTReader.h
