A standardized extended field-of-view sonographic examination technique of the neck is evaluated. In a prospective study we screened 50 patients suspected of having carcinoma or lymphoma for enlarged cervical lymph nodes. After conventional CT of the neck, extended field-of-view sonography was performed using defined axial parallel scanning sequences. The(More)
Through high-performance computer processing it has become possible to realize a new ultrasound imaging process: SieScape imaging. This method provides extended field of view images in real time using successive ultrasound images obtained when a standard transducer is scanned over a distance of up to 60 cm without any position sensor. SieScape offers new(More)
Introduction. Does high-resolution visualization of microcalcifications improve diagnostic reliability? Method. X-rays were taken of mamma specimens with microcalcifications in 32 patients (10 malignant; 22 benign) using conventional radiography (12 Lp/mm) and high-resolution radiography (2000 Lp/mm). Histological sections were subsequently prepared and(More)
Die Entwicklung der Multimediatechnologie ermöglicht es heute, komplexe Aufgaben der Bildverarbeitung in Ultraschallsystemen on-line durchzuführen, die bislang nur auf externen Workstations oder PC zu lösen waren. Die Integation eines progammierbaren Image Processors in das System Sonoline® Elegra (Siemens AG, Berlin und München) [5] eröffnet neue(More)
