A technique for interrogation of fiber-optic extrinsic Fabry-Perot interferometry sensors, based on adaptive filtering, is reported. This approach achieves 9.6 pm accuracy on Fabry-Perot cavity length (equivalent to 0.045 mmHg pressure) and improved noise resilience.
The Hemoglobin (Hb) concentration in human blood is an important parameter to evaluate the physiological condition. A hemoglobin test reveals how much hemoglobin is to be found in the blood. With this information anemia (a low hemoglobin level) and polycythemia vera (a high hemoglobin level) can be a diagnosed and monitored. It is also possible to observe… (More)
BACKGROUND The erosion of the early mortality advantage of elective endovascular aneurysm repair (EVAR) compared with open repair of abdominal aortic aneurysm remains without a satisfactory explanation. METHODS An individual-patient data meta-analysis of four multicentre randomized trials of EVAR versus open repair was conducted to a prespecified analysis… (More)
The goal of this study was to formulate and evaluate side effects of transdermal delivery of proniosomal gel compared to oral tolterodine tartrate (TT) for the treatment of overactive bladder (OAB). Proniosomal gels are surfactants, lipids and soy lecithin, prepared by coacervation phase separation. Formulations were analyzed for drug entrapment efficiency… (More)
Urodynamic analysis carried out with biocompatible catheterized fiber-optic probes, for dual measurement of pressure in bladder and in rectum, is presented. Medical tests have been performed in-vivo on seven patients; main highlights are reported.
A dual extrinsic Fabry-Perot interferometer fibre Bragg grating (EFPI/FBG) pressure and temperature sensing architecture, biocompatible and with minimum cross-sensitivity, is presented. The system performs online monitoring of radiofrequency thermal ablation in liver tumor, detecting the physical phenomena; ex-vivo experiments are reported.
Non-invasive and continuous accurate monitoring of a patients cardiovascular system can help to assure the early detection of potential abnormalities and trigger a prompt hemodynamic assessment. Such an assessment system is possible due to current advances in optical spectroscopy and signal processing. This paper presents a novel optical sensor system which… (More)
