PERFUSION VISUALISATION Russian patent published in 2015 - IPC A61B6/03 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to methods and devices for perfusion visualisation. The method includes the determination of two energy-dependent components basing on projection data from two spectral scannings, which are not agent-based. The first of the two spectral scannings is carried out at the first emission voltage, the second one - at the second emission voltage. After that, determined are two energy-dependent components and an agent-based component, basing on the two energy-dependent components. By means of a decomposition device the projection data of a time line, based on an agent, are decomposed for the object into one agent-based component, basing on the two energy-dependent components. Decomposition is performed basing on the projection data of the time line, based on the agent of the two energy-dependent components. The device for the projection data decomposition contains a device of the time line decomposition, determining the projection data, based on the agent with the application of the two energy-dependent components. The visualisation device also includes a computer-readable carrier, which contains instructions, making a computer perform operations of the perfusion visualisation method.

EFFECT: application of the invention makes it possible to reduce artefacts of the beam stiffness increase.
