Detailed Description

template<class Type>
class usImagePostScan2D< Type >

2D post-scan ultrasound image.

This class represents a 2D post-scan ultrasound image. This image is nothing more than a vpImage that contains ultrasound 2D post-scan data and additional settings that give information about the acquisition process done by the transducer. The bitmap storage is done in row-major.

The settings associated to an usImagePostScan2D image are the following:

The following figure summarize these settings and shows the structure of an usImagePostScan2D image:

The following example shows how to build a 2D post-scan ultrasound image from a vpImage and from acquisition settings.

#include <visp3/ustk_core/usImagePostScan2D.h>
int main()
{
// 2D post-scan image settings
unsigned int width = 320;
unsigned int height = 240;
double transducerRadius = 0.045;
double scanLinePitch = 0.0012;
unsigned int scanLineNumber = 256;
bool isTransducerConvex = true;
double widthResolution = 0.002;
double heightResolution = 0.002;
vpImage<unsigned char> I(height, width);
