Detailed Description

template<class TPixel>
class itk::PhasedArray3DSpecialCoordinatesImage< TPixel >

Templated 3D nonrectilinear-coordinate image class for phased-array "range" images.

y-axis <--------------------+ |\ / | \ `~-| \ / | \ ele- | \ / vation | \ projection | v x-axis to y-z plane -> o | v z-axis

In a phased array "range" image, a point in space is represented by the angle between its projection onto the x-z plane and the z-axis (the azimuth coordinate), the angle between its projection onto the y-z plane and the z-axis (the elevation coordinate), and by its distance from the origin (the radius). See the diagram above, which illustrates elevation.

The equations form performing the conversion from Cartesian coordinates to 3D phased array coordinates are as follows:

azimuth = arctan(x/y) elevation = arctan(y/z) radius = vcl_sqrt(x^2 + y^2 + z^2)

The reversed transforms are:

z = radius / vcl_sqrt(1 + (tan(azimuth))^2 + (tan(elevation))^2 ); x = z * vcl_tan(azimuth) y = z * vcl_tan(elevation)

PhasedArray3DSpecialCoordinatesImages are templated over a pixel type and follow the SpecialCoordinatesImage interface. The data in an image is arranged in a 1D array as [radius-index][elevation-index][azimuth-index] with azimuth-index varying most rapidly. The Index type reverses the order so that Index[0] = azimuth-index, Index[1] = elevation-index, and Index[2] = radius-index.

Azimuth is discretized into m_AzimuthAngularSeparation intervals per angular voxel, the most negative azimuth interval containing data is then mapped to azimuth-index=0, and the largest azimuth interval containing data is then mapped to azimuth-index=( number of samples along azimuth axis - 1 ). Elevation is discretized in the same manner. This way, the mapping to Cartesian space is symmetric about the z axis such that the line defined by azimuth/2,elevation/2 = z-axis. Radius is discretized into m_RadiusSampleSize units per angular voxel. The smallest range interval containing data is then mapped to radius-index=0, such that radius = m_FirstSampleDistance + (radius-index * m_RadiusSampleSize).
