Background: Photon attenuation as an inevitable physical phenomenon influences on the diagnostic information of SPECT images and results to errors in accuracy of quantitative measurements. This can be corrected via different physical or mathematical approaches. As the correction equation in mathematical approaches is nonlinear, in this study a new method of linearization called ‘Piece ...

Transmission of visual documentation between a neurosurgery center and a regional hospital, with a mobile phone, significantly improves consultation on a craniocerebral injury. This is one of the methods of fast consultation on image documentation (CT). We reported on one year of experience (September 2007 to September 2008) of our department with this method of image transmission in 16 patient...

The present study evaluated through a morphometric analysis the temporomandibular joint (TMJ) to estimate sex. Participants in database with archived tomographic images of patients who sought Radiology Clinic Hospital Universitário Oswaldo Cruz/University Pernambuco for face or skull tomography were evaluated. Gender was recorded while participant underwent exam and indexed database. tomographi...

We present a concept for a medical video server extended by a DICOM interface. DICOM conform security mechanisms will be integrated to enable secure Internet access. Especially digital stereoscopic video sequences (DSVS) that are relevant for surgery should be examined regarding clip length necessary for diagnosis and documentation and clip size manageable with today’s hardware. Methods for DSV...

Medical image data generally need a huge amount of resources for storage and transmission. In recent years, due to the extensive popularity of medical imaging applications in healthcare settings and the increased interest in telemedicine technologies, it is important to minimize both storage and transmission bandwidth necessities required for archival and communication of related data, preferab...

This paper presents our contributions in the design and implementation of a DICOM compliant environment for structured reporting in echocardiography. A structuring methodology of the medical information aiming to extend the set of contexts and templates with those corresponding to non-numerical findings is the first major contribution. The enhancement of DICOM mechanisms used in the report crea...

Skin dose assessment in interventional radiology (IR) procedures can be made retrospectively by using the dose-area product (DAP) registered and data provided by the DICOM header, in facilities having a PACS or other alternative image archiving system, such as medical CD-ROM under DICOM standard. Patient skin dose evaluation based on this method can help to decide on the need for further clinic...

Dieser Beitrag gibt einen Überblick über das BMBF SAMBA-Projekt. Forschungsziel des Antrags ist die die Implementierung eines service-orientierten Frameworks für die Entwicklung flexibler und generischer Anwendungen im Bereich der vorklinischen und klinischen Forschung. 1 Einleitung und Problemstellung Bildgebende Verfahren haben sich in der forschenden Pharmaindustrie sowohl im vorklinischen a...

Our goal was to develop a system that would allow us to recreate live patient arterial pathology by using an industrial technique known as stereolithography (or rapid prototyping). In industry, drawings rendered into dicom files can be exported to a computer programmed to drive various industrial tools. Those tools then make a 3D structure shown by the original drawings. We manipulated CT scan ...
