In the field of vascular catheterization it is important to reduce the radiation dose absorbed by the patient and health personnel. We propose a hardware/software integrated system which provides the physician with the possibility of performing these interventions by using an extremely reduced number of RX scans with respect to the usual practice.

Our system includes:

  • Development of an automatic system for adaptive acquisition of the most informative angiography projections and reconstruction of the digital three-dimensional model of the patient circulation system
  • Development of a graphical representation system of the three-dimensional reconstructed model reporting, in real time, the catheter position inside the model
  • Installation and calibration of a positioning system and its integration with the reconstruction and graphical representation systems

Acquisition of most informative angiography projections is realised by using a variation of some adaptive acquisition algorithms developed in the field of Magnetic Resonance (MR) tomography. Differing from existing algorithms, the new algorithms performs the analysis of each RX projection by using a function containing a digital filter to distinguish between vessel information (useful) and other tissue information (not useful). Moreover it uses as a-priori information the circular shape of vessel sections. The output of the acquisition algorithm is a reduced set of projections with higher information content and with no loss of sample information. This method uses fewer projections and thus reduces the radiation dose. The reconstruction algorithm of the three-dimensional model includes an interpolation technique in order to recover the undersampled directions. The reconstruction algorithm takes into account the circular section of the vessels, in order to correctly evaluate their shape and space position.

New - Python Face Recognition
 Biometric Authentication with Python We have developed a fast and reliable Python code for face recognition based on Principal Component Analysis (PCA). Proposed algorithm results computationally inexpensive and it can run also in a low-cost pc such as Raspberry PI.
New - Raspberry PI Remote Desktop
 Raspberry PI Remote Desktop A complete and detailed PDF tutorial to learn how to connect to and from a Raspberry PI using Remote Desktop.
New - Speaker Verification System
 Text-Independent Speaker Authentication There are two major applications of speaker recognition technologies and methodologies. If the speaker claims to be of a certain identity and the voice is used to verify this claim, this is called verification or authentication.
New - Java Face Recognition
 Java-based Biometric Authentication System Face recognition is essential in many applications, including mugshot matching, surveillance, access control and personal identification, and forensic and law enforcement applications.
New - White Papers
 High Capacity Wavelet Watermarking Using CDMA Multilevel Codes This paper proposes a technique based on CDMA and multilevel coding in order to achieve a high capacity watermarking scheme. The bits of watermark are grouped together and for each sequence a different modulation coefficient is used.
New - WebCam Face Identification
 Face Recognition Based on Fractional Gaussian Derivatives Local photometric descriptors computed for interest regions have proven to be very successful in applications such as wide baseline matching, object recognition, texture recognition, image retrieval, robot localization, video data mining, building panoramas, and recognition of object categories.
New - Speaker Recognition System
 Source code for speaker recognition
Speaker recognition is the process of automatically recognizing who is speaking on the basis of individual information included in speech waves.
New - Speech Recognition System
 Source code for isolated words recognition
Speech recognition technology is used more and more for telephone applications like travel booking and information, financial account information, customer service call routing, and directory assistance. Using constrained grammar recognition, such applications can achieve remarkably high accuracy.
