Objective To design, build and evaluate a storage model able to manage heterogeneous DICOM images. The model must be simple, but flexible enough to accommodate variable content without structural modifications; must be effective on answering query/retrieval operations according to the DICOM standard, and must provide performance gains on querying/retrieving content to justify its adoption by im...

In this paper we describe a computer-aided diagnosis (CAD) system for automated detection of pulmonary nodules in computed-tomography (CT) images. After extracting the pulmonary parenchyma using a combination of image processing techniques, a region growing method is applied to detect nodules based on 3D geometric features. We applied the CAD system to CT scans collected in a screening program ...

Aim: To describes step by for the procedures manual cephalometric analysis of facial profile was performed using Ricketts' VERT index through software not specific which accepts any DICOM format cone-beam computed tomography (CBCT) images. Material and methods: The classification means arithmetic mean values obtained (facial axis, height, mandibular plane angle, lower height arch angle). Result...

The current issues (April issue) of the Journal of the American College of Cardiology (JACC) and the European Heart Journal (Eur Heart J) contain three related manuscripts that report the findings of a major international clinical study of the impact of digital data compression on the diagnostic accuracy of coronary angiography. Because the topic is complex and most practitioners have a limited...

Digital Imaging and Communication in Medicine (DICOM) is a communication protocol that imaging devices use to communicate. The universal acceptance of the DICOM standard by the major medical vendors means that the digital transition in veterinary medicine should be relatively smooth provided DICOM is used. DICOM service objects, roles, service classes, and conformance standards are discussed. T...

Kurzfassung. Vorgestellt wird ein Verfahren zur präzisen Erstellung von 3D-Modellen anatomischer Strukturen aus äquidistanten, histologischen Schliffbildern. Dazu wird der Bildstapel zueinander registriert und ins DICOM-Format konvertiert. Der so entstandene Schliffbild-Datensatz bietet eine hochdetaillierte Auflösung und kann analog zu bzw. in Kombination mit konventionellen Bildgebungsverfahr...

Zusammenfassung. Die MR-Mammographie ist eine sehr sensitive Methode zur Erkennung von Brustkrebs. Dabei wird das Anreicherungsverhalten von Kontrastmittel in dem Gewebe mit Hilfe der Bildgebung verfolgt. Die Auswerteprogramme, die von den unterschiedlichen Kernspintomographenhersteller angeboten werden, sind jedoch zur Untersuchung dynamischer Bildserien häufig nur begrenzt geeignet. Deshalb w...

With the increasingly using of LIDC data in lung cancer research, education, and clinical medicine areas, the needs for effectively accessing and visualizing the CT scans and annotations collected by LIDC is more and more underscored. In this paper, we introduce the data integration and visualization software for the LIDC data exploration. A XML-based data model is provided for storing the LIDC...

The article is dealing with novel and relatively complex computer system for automatic creation of human tissues geometrical models. Applications of the created models can be found in orthopedy, aesthetic surgery, dental surgery, etc. On the input are discrete volume CT/MR data in DICOM 3.0 data format. The models creation process consist of several steps: tissue segmentation, volume data vecto...
