چکیده
This study proposes a calibration method and analyses the effect of this in lung measures, using minimally invasive electrical impedance spectroscopy with 3-electrode method, for tissue differentiation between healthy neoplasm tissue. Tissue measurements were performed 99 patients [54 15 neoplastic samples obtained] an indicated bronchoscopy. Statistically significant difference (P < 0.001) found bioimpedance parameters. The measures respect to measure bronchi reduces inter-patient dispersion, increasing sensitivity, decreasing specificity area below ROC curve three out four impedance-derived estimators. Results also show that there are no differences among smoker, non-smoker ex-smoker samples, which was initially stated as possible cause EIS measurement dispersion lungs.

Minimally Invasive Projector Calibration for 3D Applications
Addressing the typically time consuming adjustment of projector equipment in VR installations we propose an easy to implement projector calibration method that effectively corrects images projected onto planar surfaces and which does not require any additional hardware. For hardware accelerated 3D applications only the projection matrix has to be modified slightly thus there is no performance i...

متن کاملMinimally Invasive Surgery for Pseudopapillary Neoplasm of the Pancreas
BACKGROUND Solid pseudopapillary pancreatic neoplasia is usually a large well-circumscribed pancreatic mass, with cystic and solid areas more frequently found in young women. It is a benign pancreatic neoplasia in most cases, therefore minimally invasive surgery could be an interesting approach. AIM Evaluate the results of minimally invasive surgery for this neoplasia. METHODS Patients with...
متن کاملBeef meat electrical impedance spectroscopy and anisotropy sensing for non-invasive early assessment of meat ageing
The objective of this work was to study the electrical anisotropy behaviour of beef meat during maturation for the purpose of early assessment of meat ageing. Early assessment of beef meat fibre strength allows customised ageing of raw materials and optimisation of refrigerated storage times. During the maturation phase connection proteins break down, causing structural changes, fragmentation o...
