Characterization of pulmonary emboli ex vivo by magnetic resonance imaging and ultrasound

Magnetic resonance imaging (MRI) and transesophageal ultrasound (US) were the methods chosen for detection and characterization of central pulmonary emboli. Thirty-six ex vivo pulmonary emboli, obtained during routine autopsies who died of massive pulmonary embolism, were subjected to US imaging and MRI with high resolution. MRI and US imaging techniques were proven to be effective in characterization of pulmonary emboli, thus enabling proper treatment. The study established new information about medical imaging methods and diagnostics of pathological tissue changes and injuries.

Human body modelling for traffic accident analysis

The comparison between the measured and simulated response helped evaluate the effect of resistive joint properties upon human body motion during a collision. Unsatisfactory values of model parameters resulted in significant deviations which may lead to an incorrect evaluation of loads and risks of injuries during vehicle collision. The paper presents a complete individualised procedure of modelling and parameter identification which takes into account anthropometric variations and impact conditions. The procedure effectively neutralizes the unrealibility of standard verification corridors.

Anatomy and surgical relevance of the hepatocaval ligament : a study on cadaveric livers

The expertise in detailed anatomical characteristics of the hepatocaval ligament and its relations to the right hepatic vein (RHV) is of great significance during the right hemiliver surgery resulting from liver trauma in traffic accidents etc. A dissection of the right hemiliver with the exact preparation and measuring of the hepatocaval ligament and the extrahepatic part of the RHV was performed. In all cases resection of the ligament revealed the extrahepatic part of the RHV and thus facilitated extrahepatic vascular control in 85% and extrahepatic resection of the RHV in 52% of the cases.

Biomechanical data

The paper presents methods of the acquisition of biomechanical data which is applied in the analysis of traffic accidents. Presented are the methods of human body modelling and software implementations. The paper also provides a detailed description of the medical imaging method and geometrical reconstruction which was applied and improved within the scope of research activities of the research group. Achievable accuracy of the mass property evaluation is of the order 1%. It enables individualised acquisition of mechanical data.

Genetic algorithm in material model parameters' identification for low-cycle fatigue

The material model presented in this paper describes elasto-plastic behaviour of the material under a cyclic load application. It takes into account damage occurrence and accumulation in the material. Due to its distinct non-linearity, application of advanced methods for material parameter idetification is necessary. In the research process, a genetic algorithm was developed which indicated a fast and reliable convergence in the identification of material model parameters. This enables detection of a lower limit of the material damage occurence.
