Detailed Description

Testing / debugging algorithm, that creates a stream of channel data, containing the echo of one or more point scatterers.

The AcquisitionSequence, Transducer, and echo, transmit, and noise amplitudes are configurable.

The phantom structure can be selected for different analysis and it can be positionied freely relative to the probe origin. If the python package pySimus is installed, the channel data can be simulated using the SIMUS simulation. Otherwise (or if desired) the channel data is simulated using a simple model.

Member Enumeration Documentation

One scatterer at the origin.

Member Function Documentation

◆ getNextAcquisition()

std::vector< std::pair< std::unique_ptr< SharedImage >, DataComponentList > > ImFusion::US::SimulatedChannelDataStream::getNextAcquisition ( )

Returns the next image that would have been emitted on the stream synchronously, together with its associated components.

The image will not be emitted on the stream anymore, so if mixed with streaming it changes the order of emitted images. This is useful for testing consumers of channel data.

◆ size()

int ImFusion::US::SimulatedChannelDataStream::size ( ) const
overridevirtual

Returns the number of images of the image stream per emission.

Reimplemented from ImFusion::ImageStream.

◆ configure()

void ImFusion::US::SimulatedChannelDataStream::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 ImFusion::Configurable.

◆ configuration()

void ImFusion::US::SimulatedChannelDataStream::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

Reimplemented from ImFusion::Configurable.

◆ uuid()

std::string ImFusion::US::SimulatedChannelDataStream::uuid ( )
overridevirtual

Unique identifier for stream.

Deprecated
"Method Stream::uuid is deprecated and should not be used to identify stream instances or hardware resources"

Reimplemented from ImFusion::Stream.

◆ openImpl()

bool ImFusion::US::SimulatedChannelDataStream::openImpl ( )
overrideprotectedvirtual

Open stream.

Returns whether the operation was successful. This method is responsible for allocating necessary resources, initializing device handles, and establishing connections to devices. Implementers should ensure that all one-time setup tasks are completed here.

Implements ImFusion::Stream.

◆ closeImpl()

bool ImFusion::US::SimulatedChannelDataStream::closeImpl ( )
overrideprotectedvirtual

Close stream.

Returns whether the operation was successful. This method should be used to free any resources that were allocated during the openImpl() call and to disconnect from any devices. Implementers must ensure that all resources are properly released to avoid memory leaks.

Implements ImFusion::Stream.

◆ startImpl()

bool ImFusion::US::SimulatedChannelDataStream::startImpl ( )
overrideprotectedvirtual

Start stream.

Returns whether the operation was successful. This method is intended to initiate the actual data readout process or to connect a callback function for data handling. Implementers should ensure that the stream is ready and producing data after this call.

Implements ImFusion::Stream.

◆ stopImpl()

bool ImFusion::US::SimulatedChannelDataStream::stopImpl ( )
overrideprotectedvirtual

Stop stream.

Returns whether the operation was successful. This method should halt any ongoing data readouts or callbacks, effectively pausing the data flow to reduce CPU load. Implementers should ensure that the stream can be restarted after this call.

Implements ImFusion::Stream.

◆ pauseImpl()

bool ImFusion::US::SimulatedChannelDataStream::pauseImpl ( )
overrideprotectedvirtual

Pause stream (not required to be supported).

Returns whether the operation was successful. This method is intended to temporarily pause data acquisition.

Reimplemented from ImFusion::Stream.

◆ resumeImpl()

bool ImFusion::US::SimulatedChannelDataStream::resumeImpl ( )
overrideprotectedvirtual

Resume stream from pause (only required to be supported when pauseImpl() is supported).

Returns whether the operation was successful. This method should resume data acquisition after a pause.

Reimplemented from ImFusion::Stream.

◆ supportsPausing()

bool ImFusion::US::SimulatedChannelDataStream::supportsPausing ( ) const
inlineoverrideprotectedvirtual

Override and return true if this stream implements the pausing and resume operations.

Overridden method must be constexpr-essible and thread-safe.

Reimplemented from ImFusion::Stream.

◆ doWork()

std::optional< WorkContinuation > ImFusion::US::SimulatedChannelDataStream::doWork ( )
overrideprotectedvirtual

Create one StreamData and publish it (this function will be called at the desired frame rate) If this is not desired, you can do the following: return std::nullopt;.

Implements ImFusion::Stream.
