Sarcomas of the soft tissue constitute a fairly rare group of neoplasms localized mainly at the level of the extremities. Apart from clinical and semeiotic investigations, diagnosis is based on imaging techniques. Among these (ultrasound, CT, NMR and angiography), all of which are helpful in diagnosis, NMR seems to provide the most complete data and(More)
OBJECTIVE Perioperative myocardial ischemia is less pronounced in off-pump coronary artery bypass (OPCAB) compared to on-pump coronary artery bypass; however, the threshold over which the postoperative release of cardiac troponin I (cTnI) release and creatine kinase-MB (CK-MB) after OPCAB should be considered clinically relevant is unknown. The study was(More)
The Multi-Chromatic Analysis, as introduced in [1], uses interferometric pairs of SAR images processed at range sub-bands and explores the phase trend of each pixel as a function of the different central carrier frequencies. The phase of suitable " frequency-coherent " scatterers evolves linearly with the sub-band central wavelength, the slope being(More)
I n this paper we propose a specialized hardware architecture for the real time visual navigation of a mobile robot. The adopted navigation method is based on a two-steps approach. Features are extracted and matched over an image sequence which is captured by a video-camera (mounted on a mobile robot) during its motion. As a result, a 2D motion field is(More)
Operational monitoring of slope instabilities by SAR Interferometry poses a number of challenges due to the limited spatial extent of the landslide areas and rainy conditions usually associated with mass movement events. In this work we present the results of the application of both conventional DInSAR techniques, and a point-by-point, multitemporal study(More)
Use of mean-field annealing theory is proposed for solving the phase-unwrapping (PU) problem. PU is formulated as a constrained optimization problem for the field of integer corrections to be added to the wrapped gradient field. A deterministic algorithm is described to provide an approximation of the average of the correction field over the global minima(More)
