Detailed Description

Ultrasound scan-conversion for curved and phased array data.

This algorithm performs scan-conversion from a set of scanlines to a volumetric image and vice versa; this operation can be taken out by either the CPU or GPU. In addition to its usual algorithm interface, this class also supports computation of individual scans through calling compute().

The following example illustrates how to convert from a scan to a volume using the CPU and back using the GPU.

SharedImage si = obtainScan(); // Get the scans from another process
 
auto scAlg = std::make_unique<ScanConversion>();
scAlg->setUseGPU(false);
 
std::shared_ptr<SharedImage> volume = scAlg->compute(&si);
 
scAlg->setUseGPU(true);
scAlg->setInverse(true);
std::shared_ptr<SharedImage> scans = scAlg->compute(&si);

Member Function Documentation

◆ setFrameGeometry()

void setFrameGeometry	(	std::unique_ptr< US::FrameGeometry >	fg,
		const ImageDescriptor *	outDesc = nullptr )

Define convex or sector geometry for scan-conversion.

Unless there is a dedicated output descriptor specified, the input descriptor (set on the frame geometry) is used to estimate a suitable output image size.

◆ compute()

void compute ( )

overridevirtual

Execute the algorithm.

Implements Algorithm.

◆ takeOutput()

OwningDataList takeOutput ( )

overridevirtual

Return any new Data that was created by the Algorithm during the last call to compute().

The default implementation will return an empty list.

Note: Since ownership of the data is transferred, you can call this method only once between calls to compute().

Reimplemented from Algorithm.

◆ configure()

void configure ( const Properties * p )

overridevirtual

Configure this object instance by de-serializing the given Properties.

The default implementation will do so automatically for all registered Parameter and SubProperty instances.

See also: configuration() for the inverse functionality

Reimplemented from Configurable.

◆ configuration()

void configuration ( Properties * p ) const

overridevirtual

Serialize the current object configuration into the given Properties object.

The default implementation will do so automatically for all registered Parameter and SubProperty instances.

See also: configure() for the inverse functionality
