FRI Technology

FRI technology allows researchers to construct personalized 3D segmented computer models of human organs including bone, blood vessels and airways that have been scanned by imaging techniques such as computerized tomography (CT), magnetic resonance imaging (MRI) or ultrasound.  Length and volume measurements can be performed on the models to quantify certain regions and document their properties such as tumor size, for example, for follow-up.

FRI technology combines CT images with two advanced computational fluid dynamics tools – Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA).

Segmentation & visualization examples

The segmented model forms the basis for further functional analysis using either flow (see CFD) or structural (see FEA) simulations:

1. Computational Fluid Dynamics (CFD)

Computational Fluid Dynamics (CFD) analyses the motion of fluids and their interaction with surfaces. This advanced technology in aerospace engineering can be applied to healthcare, accurately describing the patient’s “geometry” (lungs, arteries, heart, etc.) and “boundary” conditions (blood flow velocity, airflow pressures, etc.). This results in a patient-specific model for detailed, functional imaging.

CFD analyses different medical interventions and treatments:

  • Ventilation assessment of the respiratory system
  • Particle deposition of inhalation therapies
  • Assessment of local interventions for snoring and sleep apnea
  • Virtual surgery for nasal septum corrections
  • Analyses of mechanical devices (valves, stents, etc.) in bronchi, veins and arteries

Close cooperation between healthcare experts with clinical experience and experts in numeric modeling ensure high-quality results.

2. Finite element analysis (FEA)

Finite element analysis (FEA) analyzes the stress endured by a joint or implant. Mathematical equations describe the behavior of a structure under stress conditions such as blood pushing against the structure, muscular tension or gravity pull.

The method can be applied to:

  • Functionality analysis of stents and grafts.
  • Upper airway collapse during sleep apnea.
  • Valve dynamics in the respiratory or cardiac system.
  • Optimizing design of highly stressed implants.
  • Stresses, strains and displacements in mandibula during osteotomy surgery.
  • Assessment of mandibular movements and airway expansion with a mandibular advancement device.
