Stereotactic body radiation therapy allows for a precise and accurate dose delivery. Organ motion during treatment bears the risk of undetected high healthy tissue exposure. An organ very susceptible to is oesophagus. Its low contrast on CT oblong shape renders estimation difficult. We tackle this issue by modern algorithms measure oesophageal voxel-wise estimate related dosimetric impact. Oeso...

Material engineers use interrupted in situ tensile testing to investigate the damage mechanisms in composite materials. For each subsequent scan, the load is incrementally increased until the specimen is completely fractured. During the interrupted in situ testing of glass fiber reinforced polymers (GFRPs) defects of four types are expected to appear: matrix fracture, fiber/matrix debonding, fi...

Prediction of respiratory motion has the potential to substantially improve cancer radiation therapy. A nonlinear finite element (FE) model of respiratory motion during full breathing cycle has been developed based on patient specific pressure-volume relationship and 4D Computed Tomography (CT) data. For geometric modeling of lungs and ribcage we have constructed intermediate CAD surface which ...

PurposeQuantitative metrics in lung computed tomography (CT) images have been widely used, often without a clear connection with physiology. This work proposes patient-independent model for the estimation of well-aerated volume lungs CT (WAVE).MethodsA Gaussian fit, mean (Mu.f) and width (Sigma.f) values, was applied to lower histogram data points provide (WAVE.f). Independence from reconstruct...
