Detailed Description

This abstract class provides an interface to synthetic volumes. The requirements of this class are as follows:

  • The volume must be defined at every point inside the volume defined by [0, bounds]
  • The volume must be sliceable with any imaginable slice
  • The volume must be the same every time it is used (i.e. no randomness)
    • If you want to test noise suppression, add noise to the US slice after it has been sampled from this class.

virtual unsigned char cx::cxSyntheticVolume::evaluate ( const Vector3D &  p) const
pure virtual

Evaluate the volume at position (x, y, z). The coordinates are given in volume space.

Implemented in cx::cxSimpleSyntheticVolume, and cxtest::SphereSyntheticVolume.

virtual

Sample a set of ultrasound slices. The planes to use are defined by planes. The Transform3D-s represent the transform from image space to world space. The volume is assumed to lie from [0, 0, 0] -> bounds. If any part of an image plane is outside the definition of the volume, the pixel value will be set to 0.

Parameters
planesTransforms from image space to world space (and thus also volume space) for the desired slices.
pixelSpacingThe size of each pixel in the ultrasonic image.
sliceDimensionThe size in pixels of each ultrasound image.
noiseSigmaThe sigma of the noise distribution on each image
noiseMeanThe sigma of the noise distribution on each image
