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 …

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 …
