Shape analysis, semantic annotation and context modelling for the retrieval of 3D anatomical structures
Moroni D., Salvetti M., Salvetti O.
This paper is devoted to the presentation of a framework for the description of anatomical structures, based both on topological and geometrical features and on semantic annotation. We argue that a 3D model-representing an anatomical structure-may be enhanced with other non-geometrical pieces of information relevant to the particular problem-context. Hybrid methods for similarity searches are then introduced and shown to be able to support effective case-based reasoning procedures. The approach is illustrated with examples from several medical application fields in order to discuss its potential impact.Source: Pattern recognition and image analysis 20 (2010): 86–93. doi:10.1134/S1054661810010098

Detection limit of biomarkers using the near-infrared band-gap fluorescence of single-walled carbon nanotubes
D' Acunto M., Colantonio S., Moroni D., Salvetti O.
Progress is being made in the development of microanalytical systems for biosensing. Because the sensor signal-to-noise ratio increases with decreasing size for many devices, considerable effort to fabricate small sensors is going to be addressed. Due to their hollow cylindrical structure, carbon nanotubes (CNTs) are considered very promising for many potential nano-device applications. Fluorescence microscopy in the near-infrared (NIR) between 950 and 1600nm has been developed as a novel method to image and study single-walled carbon nanotubes (SWNTs) in a variety of environments. Recently, hybridisation of DNA using NIR band-gap fluorescence has been experimentally demonstrated. We describe a numerical simulation, where the fluorescence shift energy is connected to exciton density variation when the molecular recognition is located on the SWNT immersed in a physiological solution.Source: Journal of modern optics (Print) 57 (2010): 1695–1699. doi:10.1080/09500341003658170

The K(pi, 1) problem for the affine Artin group of type (B)over-tilde(n) and its cohomology
Callegaro F., Moroni D., Salvetti M.
We prove that the complement to the affine complex arrangement of type (B) over tilde (n) is a K(pi, 1) space. We also compute the cohomology of the affine Artin group G (B) over tilde (n) ( of type (B) over tilde (n)) with coefficients in interesting local systems. In particular, we consider the module Q [q+/-1; t+/-1]; where the first n standard generators of G (B) over tilde (n) act by (-q)-multiplication while the last generator acts by (-t)-multiplication. Such a representation generalizes the analogous 1-parameter representation related to the bundle structure over the complement to the discriminant hypersurface, endowed with the monodromy action of the associated Milnor fibre. The cohomology of G (B) over tilde (n) with trivial coefficients is derived from the previous one.Source: Journal of the European Mathematical Society (Print) 12 (2010): 1–22. doi:10.471/JEMS/187

Image mining for infomobility
Magrini M., Moroni D., Nastasi C., Pagano P., Petracca M., Pieri G., Salvadori C., Salvetti O.
The wide availability of embedded sensor platforms and low-cost camera sensors - together with the developments in wireless communication - make it now possible the conception of pervasive intelligent systems based on vision. Such systems may be understood as distributed and collaborative sensor networks, able to produce, aggregate and process images in order to mine the observed scene and communicate the relevant information found about it. In this paper, we investigate the peculiarities of visual sensor networks with respect to standard vision systems and we identify possible strategies to tackle the image mining problem. We argue that multi-node processing methods may be envisaged to decompose a complex task into a hierarchy of computationally simpler problems to be solved over the nodes of the network. We illustrate these ideas by describing an application of visual sensor network to infomobility.Source: 3rd International Workshop on Image Mining Theory and Applications, pp. 35–44, Angers, France, 20-21 May 2010

POR Toscana IPERMOB: A Pervasive and Heterogeneous Infrastructure to control Urban Mobility in Real-Time
Magrini M., Moroni D., Pieri G., Salvetti O.
Within the domain of “Intelligent Transport Systems IPERMOB proposes a multi-tier approach for developing an Information System for urban mobility. IPERMOB proposes a new generation of integrated systems based on the optimization and inter-operability of the chain formed by: i) data collection systems; ii) aggregation, management, and on-line control systems; off-line systems aiming at infrastructure planning; iii) information systems targeted to citizen and municipality to handle and rule the vehicle mobility. Specifically IPERMOB proposes low-cost wireless technology (WSN) and image processing techniques to estimate traffic-related information. In IPERMOB vehicular networks (IEEE 802.11a/p) will be interoperated with WSN (IEEE 802.15.4) and connected to a centralized database through wide band 5 GHz link (IEEE 802.11h). As tested, IPERMOB will provide real-time information about parking availability and vehicle flows on the landside of the International Airport of Tuscany (Pisa).

Quantification of epicardial fat by cardiac CT imaging
Coppini G., Favilla R., Marraccini P., Moroni D., Pieri G.
The aim of this work is to introduce and design image processing methods for the quantitative analysis of epicardial fat by using cardiac CT imaging. Indeed, epicardial fat has recently been shown to correlate with cardiovascular disease, cardiovascular risk factors and metabolic syndrome. However, many concerns still remain about the methods for measuring epicardial fat, its regional distribution on the myocardium and the accuracy and reproducibility of the measurements. In this paper, a method is proposed for the analysis of single-frame 3D images obtained by the standard acquisition protocol used for coronary calcium scoring. In the design of the method, much attention has been payed to the minimization of user intervention and to reproducibility issues. In particular, the proposed method features a two step segmentation algorithm suitable for the analysis of epicardial fat. In the first step of the algorithm, an analysis of epicardial fat intensity distribution is carried out in order to define suitable thresholds for a first rough segmentation. In the second step, a variational formulation of level set methods - including a specially-designed region homogeneity energy based on Gaussian mixture models- is used to recover spatial coherence and smoothness of fat depots. Experimental results show that the introduced method may be efficiently used for the quantification of epicardial fat.Source: The Open medical informatics journal 4 (2010): 126–135. doi:10.2174/1874431101004010126

A knowledge-based infrastructure for the management of diagnostic imaging procedures in the heart failure domain
Martinelli M., Moroni D., Salvetti O., Tampucci M.
Within the European HEARTFAID Project, an integrated platform of services has been developed to assist chronic heart failure stakeholders in their routine workflow and to provide an optimal management of heart failure patients, by exploiting the most advanced technologies, innovative methods for diagnostic data processing, and significant and up-to-date knowledge, suitably formalized. Since signal and imaging investigations are currently a basic step of the diagnostic, prognostic and follow-up processes of heart diseases, the platform has been designed so as to include an advanced system for the management, storage and deployment of the related heterogeneous information, ranging from the raw data - consisting in 1D signals, 2D/3D images and image sequences - to the extracted quantitative parameters and, finally, to their interpretation. The purpose of this paper is to describe an effective way to obtain an integrated management of all the data and transactions across the distributed repositories necessary to deal with such workflows. Intelligent knowledge-based services are also provided for assisting - in a holistic approach - all the decision making processes related to those data. In particular, among the several functionalities provided by HEARTFAID platform, the paper focuses on the integration of echocardiography workflows. To this end, a suitably developed standard-compliant IT infrastructure called EchoCardio Lab is introduced and architectural details of its components are given.Source: TRANSACTIONS ON MASS-DATA ANALYSIS OF IMAGES AND SIGNALS 2 (2010): 3–18.

Computer technology for the quantification of pericardial fat assessed through cardiac CT
Coppini G., Favilla R., Moroni D., Pieri G., Schlueter M., Bianchi M., Coceani M., Mazzarisi A., Salvetti O., Marraccini P.
Pericardial fat is associated with the extent of coronary artery disease (CAD) and with cardiovascular mortality. The aim of the study was to develop a computer software for the detection and measurement of pericardial fat in patients with suspected CAD. Methods: A dedicated software was developed to quantify pericardial fat from standard calcium score scans (acquisition triggered at 70% of the R-R interval, image reconstruction with a slice thickness of 2.5 mm without overlap). The procedure is based on the following phases: 1) A trace of the pericardial boundary in two orthogonal long-axis slices of the heart is performed by the operator. 2) An initial and approximate representation of the pericardial surface is generated. 3) The pericardial fat is then segmented by applying a Level Set method; 4) The ventricular region is defined by recognizing the atrioventricular groove and split in two by the interventricular groove. 5) If necessary, further manual editing of the pericardial boundary can be carried out. The method output provides the total volume of pericardial fat, as well as the regional distribution of fat in the right and left ventricles. Results: To test the performance of the software, we used scans from a set of 22 patients (63±8 years, 64% male, body mass index [BMI] 27.4±5.2 kg/m2) referred to our Institute for suspected CAD and undergoing cardiac CT. The average time needed to complete the analysis of pericardial fat was less than five minutes. In our patient sample, we observed a total pericardial volume of 95.7±32.1 mm3, which was divided unevenly between the right (59.4±28.3 mm3) and left (38.9±12.6 mm3) ventricles. Conclusions: Pericardial fat volume may be assessed non-invasively through cardiac CT, without leading to increased radiological exposure and post-processing times. The use of a computer software, such as the one tested in the present study, permits a systematic evaluation of epicardial fat that may prove useful for the risk sSource: European heart journal 31 (2010): 436–436.

Decision support in heart failure through processing of electro- and echocardiograms
Chiarugi F., Colantonio S., Emmanouilidou D., Martinelli M., Moroni D., Salvetti O.
Objective: Signal and imaging investigations are currently key components in the diagnosis, prognosis and follow up of heart diseases. Nowadays, the need for more efficient, cost-effective and personalised care has led to a renaissance of clinical decision support systems (CDSSs). The purpose of this paper is to present an effective way of achieving a high-level integration of signal and image processing methods in the general process of care, by means of a clinical decision support system, and to discuss the advantages of such an approach. From the wide range of heart diseases, heart failure, whose complexity best highlights the benefits of this integration, has been selected. Methods: After an analysis of users' needs and expectations, significant and suitably designed image and signal processing algorithms are introduced to objectively and reliably evaluate important features involved in decisional problems in the heart failure domain. Then, a CDSS is conceived so as to combine the domain knowledge with advanced analytical tools for data processing. In particular, the relevant and significant medical knowledge and experts' knowhow are formalised according to an ontological formalism, suitably augmented with a base of rules for inferential reasoning. Results: The proposed methods were tested and evaluated in the daily practice of the physicians operating at the Department of Cardiology, University Magna Graecia, Catanzaro, Italy, on a population of 79 patients. Different scenarios, involving decisional problems based on the analysis of biomedical signals and images, were considered. In these scenarios, after some training and 3 months of use, the CDSS was able to provide important and useful suggestions in routine workflows, by integrating the clinical parameters computed through the developed methods for echocardiographic image segmentation and the algorithms for electrocardiography processing. Conclusions: The CDSS allows the integration of signal and image procSource: Artificial intelligence in medicine (Print) 50 (2010): 95–104. doi:10.1016/j.artmed.2010.05.001
