Abstract Continuous, real-time monitoring of perfusion after microsurgical free tissue transfer or solid organ allotransplantation procedures can facilitate early diagnosis and intervention for anastomotic thrombosis. Current technologies including Doppler systems, cutaneous O 2 -sensing probes, fluorine magnetic resonance imaging methods are limited by their intermittent measurements, requirements skilled personnel, indirect interfaces, and/or tethered connections. This paper reports a...
Laser speckle contrast imaging (LSCI) was used to monitor thermal-induced changes in the blood flow and diameter of mesenteric microvessels normal tumor bearing mice under 60 min treatment at different constant temperatures between 41 degrees C 45 C. The results show that increase beginning then reach a plateau finally start decrease. lower temperature, longer stays. A t-test indicates there is no significant difference values relative for same group. For mice, increases are 1.26 1.41,...
Current near-infrared spectroscopy (NIRS)-based systems for continuous flap monitoring are limited to flaps which carry a cutaneous paddle. As such, this useful and reliable technology has not previously been applicable muscle-only free where other modalities with substantial limitations continue be utilized. We present the first NIRS probe allows of local tissue oxygen saturation (StO2) directly within substance muscle tissue. This is flexible, subcentimeter in scale, waterproof,...
Objective and Impact Statement. Real-time monitoring of the temperatures regional tissue microenvironments can serve as diagnostic basis for treating various health conditions diseases. Introduction. Traditional thermal sensors allow measurements at surfaces or near-surface regions skin certain body cavities. Evaluations depth require implanted devices connected to external readout electronics via physical interfaces that lead risks infection movement constraints patient. Also, surgical...
Serial examination and direct measurement of intracompartmental pressure (ICP) are suboptimal strategies for the detection acute compartment syndrome (CS) because they operator-dependent yield information that only indirectly reflects muscle perfusion. As a result, instances unnecessary fasciotomy unrecognized CS relatively common. Recently, near-infrared spectroscopy (NIRS)-based systems monitoring have generated interest as an adjunct tool. Under ideal conditions, NIRS directly measures...
Measurement of blood perfusion has been playing an important role in the field bioheat transfer and clinical thermotherapy. However, it is not easy to gain thermal induced dynamics local tissue. Laser speckle techniques we developed were valid. In this paper, reviewed our progress on studying mice's mesentery with laser which included microscopy CCD camera for isolate vessel imaging vessels mice. The principles two kinds introduced briefly. normal tumor showed during different constant...
The optical properties of porcine liver were studied during the dehydration process at different constant temperature (37°C, 40°C,43°C, 46°C, 50°C). Each time after samples placed in thermostat for a period, weight recorded by precise electronic scale, and corresponding measured double integrating sphere system. results showed that absorption coefficient mainly depended on level tissue. In contrast, reduced scattering had more complex relation with process, which both...
In hyperthermia, blood flow plays a major role in determining the effectiveness of hyperthermia used alone or combined with radiation therapy chemotherapy. The acidity, nutritional supply, partial pressure oxygen and distribution drugs are closely related to flow. To facilitate these issues we put forward simple optical method measure dynamical change volume combining laser speckle measurement CCD microscopic imaging technique. this study, selected seven different temperatures (40°C, 42°C,...
Purpose: Direct measurement of intracompartmental pressure (ICP) and serial examination are the primary strategies for detection CS; however, these operator dependent yield information that only indirectly reflects muscle perfusion. As a result, instances unnecessary fasciotomy unrecognized compartment syndrome relatively common. Recently, near-infrared spectroscopy (NIRS)-based systems monitoring have generated interest as an adjunct tool. NIRS directly measures oxygenation (StO2), thereby...
