Frequently asked questions about X-ray tomography simulation

What is Novi-Sim X-ray tomography simulation software?

Novi-Sim is an X-ray radiography and tomography simulation software that models the complete image acquisition chain, including the X-ray source, filters, sample, scintillator, sensor, optics and camera. It generates virtual radiographs and a reconstruction module is included to compute tomographic volumes.

 

What can Novi-Sim simulate?

Novi-Sim can simulate X-ray projections from any angle and supports circular and helical tomography scanning trajectories. It can also model different acquisition configurations, including conical and parallel beam geometries.

 

Which X-ray sources are supported by Novi-Sim?

Novi-Sim simulates X-ray tubes and monochromatic sources. User-defined spectrum can be uploaded in Novi-Sim. Synchrotron radiation sources are also available in option. Users can define various source parameters and filters and then visualise the resulting spectra.

 

Can Novi-Sim simulate defects in materials?

Yes. Novi-Sim can model complex samples containing multiple materials and simulate defects such as holes, inserts and cracks. Mesh objects can be imported in STL format.

 

Can Novi-Sim simulate X-ray detectors and cameras?

Yes. The software can simulate a wide variety of scintillators sensors and cameras. Detection systems can be configured with the relevant parameters, including direct coupling for flat-panel detectors or coupling through an optical lens.

 

Can Novi-Sim be used to optimise X-ray CT acquisition parameters?

Yes. Novi-Sim can help optimise image quality and acquisition times by varying parameters such as X-ray current and voltage, source-detector distance, number of projections, exposure time, and local or global tomography configurations.
