objectives : to carry out in vivo and in vitro comparative pilot study to evaluate the preciseness of a newly proposed digital dental radiography setup. this setup was based on markers placed on an external frame to eliminate the measurement errors due to incorrect geometry in relative positioning of cone, teeth and the sensor. methods : five patients with previous panoramic images were selecte...

In recent years there has been a tremendous increase in the demand for digital imagery. Applications include consumer electronics Kodak’s Photo-CD, HDTV, SHDTV, and Sega’s CD-ROM video game , medical imaging digital radiography , video-conferencing and scientific visualization. The problem inherent to any digital image or digital video system is the large bandwidth required for transmission or ...

objectives: the optimal goal of radiography is to provide high-quality diagnostic images with the least patient radiation dose. the aim of this study was to evaluate the accuracy of cone-beam computed tomography (cbct) and intraoral photostimulable phosphor plate (psp) digital and film-based conventional radiography for detection of artificial cancellous bone defects. materials and methods: fiv...
