Les explorations arteriographiques des kystes hydatique du foie et sa comparaison avec Ia scintigraphie hepatique L' auteur present quatre cas de quarante six cas d'angiographie coeliaque et mesentrique sup2-rieure en portant son attention sur les resultats obtenus de cet examen et de...

In this paper we present an algorithm to correct 3D reconstruction errors of 3D ultrasound catheter caused by ultrasound image thickness. We also provide a method to quickly measure ultrasound image plane's thickness. With thickness correction registration accuracy of navigation system using 3D ultrasound catheters can be improved by 20%.

The rapid diagnosis of invisible internal injury in an austere and hostile front-line operational environment remains a challenge for (Canadian Forces) medical and search and rescue personnel. The availability of a portable 4D-ultrasound imaging system with a single probe, providing high image resolution and deep penetration, is considered by (civilian) medical practitioners and their military ...

Background: This study set out to evaluate the utility of cerebrovascular virtual non-contrast (VNC) scans. Materials and Methods: Conventional non-contrast (CNC) and dual-energy computed tomography angiography (DE-CTA) head scans were conducted on 100 subjects, of which 46 were normal, 15 had parenchymal hematomas of the brain, 13 had ischemic infarction, 22 had tumors, and 4 had calcified les...

intrauterine device (iud), a conventional method of contraception is rarely associated with uterine perforation and extra uterine dislocation. a 29 years old woman complaining of vaginal bleeding was referred for pelvic mass identified in ultrasound. the mass was confirmed with ct scan. in laparatomy we found an iud in cul-de-sac and pelvic mass was apparently an organized hematoma. transmigrat...

Image processing plays a vital role in the development of medical industry especially ultrasound medical images. Image acquisition is carried out using ultrasound equipments like transducer, scanner, and CPU and display device. There are mainly four modes of ultrasound imaging A-mode, M-mode, B-mode and Doppler-mode. Ultrasound imaging plays crucial role in medical imaging due to its non-invasi...

Medical ultrasound echo signals provide the basic information for obtaining the ultrasonic image in medical ultrasound technology. The statistics of the ultrasound echo signals reveals the systematic structure of the medical ultrasonic image via analyzing the corresponding statistical distributions. A novel statistical distribution, the ascending order K distribution, was proposed here to model...
