Radiographic images can provide quantitative as well as quantitative information if they are subjected to densitometric analysis. Digital radiography consists of four major steps which include X-ray detection, digitization, image processing and display. The digitization process varies from device to device and may suffer variations even when the same digital equipment is used throughout time. A...

The need to visualize soft-tissue components of the temporomandibular joint (TMJ) and the knowledge of the growing use of computed tomography (CT) in medical diagnostic imaging prompted one author (E. L. C.) to consider its potential for TMJ evaluation. The experience with our first patient who had an anteriorly dislocated joint disk has stimulated the use of CT for patients in the TMJ clinic. ...

The problems of corrosion and deposit are crucial issues in the pipelines of the chemical, nuclear and petrochemical industries. Radiography (neutron, gamma, X-ray) has long been used as a technique for pipe inspection and corrosion monitoring. The 10MW Budapest research reactor site is a source of various energy neutron (thermal and epithermal) and gamma radiation. The detector system was a Pe...

The reliability of angiographically determined left ventricular (LV) volume is in part dependent upon the accuracy of the determination of the position of the left ventricular (LV) chamber in rehtion to the x-ray image intensifier. A new device is described which utilizes available ultrasound techniques and equipment to ascertain readily the height of the LV above the table top with the patient...

The rapid growth in information and communication technologies has advances the medical data management systems immensely. In this regard, many different techniques and also the advanced equipment like Magnetic Resonance Imaging (MRI) Scanner, Computer Tomography (CT) scanner, Positron Emission of Tomography (PET), mammography, ultrasound, radiography etc. are used. Nowadays there is a rise of ...

The reliability of the linear tomography and panoramic radiography made with X-ray equipment was evaluated (Vera View Scope X-600; Morita). The sample was composed of 20 dry human hemimandibles, in which the area selected for analysis was 1.5 cm distal from the limit set before the mental foramen. Four measurements were made. The images obtained were drawn on acetate paper and the hemimandibles...
