Development of a Phantom Tissue for Blood Perfusion Measurements and Noninvasive Blood Perfusion Estimation in Living Tissue
… surface perfusion sensors has been developed. A phantom tissue model is used to mimic the non-directional blood flow of tissue perfusion. A computational fluid dynamics (CFD) model was constructed in Fluent to design the phantom tissue and validate the experimental results. The phantom perfusion …

Development of the Passive Perfusion Probe for Non-Invasive Blood Perfusion Measurement
… system has been developed and tested in a phantom tissue and an animal model. The system uses a small sensor with a laminated flat thermocouple to measure the heat transfer response to an arbitrary thermal event (convective or conductive) imposed on the tissue surface. Blood perfusion and …

Assessment of the Repeatability and Sensitivity of the Thermoelectric Perfusion Probe
… system that cyclically heats and cools tissue to measure blood perfusion. The probe produces the thermal event with a thermoelectric cooler and then measures the resulting heat flux and temperatures: the arterial temperature and the sensor temperature (the temperature between the heat …

Assessment of the Measurement Repeatability and Sensitivity of a Noninvasive Blood Perfusion Measuring Probe
… is the local, non-directional blood flow through tissue. It is measured as the volumetric flow rate of blood through a given volume of tissue. One method that has been developed for measuring blood perfusion is a probe that measures the temperature response of the tissue when a thermal event is …

Immobilization and Catheter Guidance for Breast Brachytherapy Using Patient-Specific Templates
… insertion was designed and fabricated for use on phantom studies. Template creation is based on a virtual reality reconstruction of the patient's anatomy from computed tomography imaging. The template fits on the patient's breast, immobilizing the soft tissue, to provide pre-planned catheter …

Fast 3D Deformable Image Registration on a GPU Computing Platform
… emerging for medical applications involving soft-tissue organs such as brain, breast, kidney, liver, prostate, etc. Computational complexity of such algorithms are significantly higher than those of conventional rigid and affine methods, leading to substantial increases in execution time. In this …

A needle-tip embedded fibre optical force sensor for tissue identification
The identification of biological tissue types during needle insertion is subject to a lack of precise monitoring techniques, especially in an intensive magnetic resonance environment. One approach to improve this situation is to attach optical sensors to the surgical needle. In this research, a …

Development of a Colonoscopy Simulator for the Evaluation of Colonoscopy Devices
… here developed simulator had to provide a colon phantom with realistic biomechanical properties as well as a sensor setup to measure signals which can be used to quantify the performance of devices which are tested within the simulator.<br/><br/>Related literature was reviewed and possible tissue …
