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)
In recent years, attention has been devoted to the possibility of retrieving accurate phase information from stable targets in long synthetic aperture radar (SAR) data series. Stable targets have been defined as objects on the Earth surface exhibiting high stability of their backscatter in the temporal and geometrical (baseline) dimensions [1]; they can be(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 videocamera (mounted on a mobile robot) during its motion. As a result, a 2D motion field is(More)
The present paper presents the results of the application of Multi Chromatic Analysis (MCA) for height retrieval by processing both AES-1 airborne data and satellite TerraSAR-X data. In particular, a test of the robustness of the MCA technique with respect to total processed bandwidth has been performed through comparison of results from datasets with(More)
