clavicular bone tumors occur in less than 0.5 percent of bone tumors. primary chondrosarcoma is very rare even among clavicle tumors. the main symptom is a touchable mass in 69 % of patients. dedicated centers using fna and cytology can reach a correct diagnosis in 94% of cases. treatment planning is done using simple x-ray, ct-scan, shoulder mri, chest ct-scan, and whole body technetium scan. ...

Industrial CT (computerized tomography) uses a series of 2-dimensional images taken at specific intervals around the entire sample. Basically any type of industrial CT system uses three principal components: an X-ray tube, an X-ray detector, and a rotational stage. Everything is enclosed within a radiation shielding steel/lead/steel cabinet that typically ranges between four and 10 feet cubed. ...

OBJECTIVES X-ray computed tomography (CT) using phase contrast can provide images with greatly enhanced soft-tissue contrast in comparison to conventional attenuation-based CT. We report on the first scan of a human specimen recorded with a phase-contrast CT system based on an x-ray grating interferometer and a conventional x-ray tube source. Feasibility and potential applications of preclinica...

This paper focuses on minimizing the time requirement for CT capture through innovative simultaneous x-ray capture method. The state-of-the-art CT imaging methodology captures a sequence of projections during which the internal organ movements may lead to poor reconstruction due to motion artefacts. Traditional CT scanners' minimize such effect by taking more projections than necessary. In this...

two main forms of copd (chronic obstructive pulmonary disease) refer to a group of lung diseases that block airflow and cause a huge degree of human suffering. a new method for identifying and estimating the severity of copd from three-dimensional (3-d) pulmonary x-ray ct images would be helpful for evaluation of treatment effects and early diagnosing is presented in this paper. this method has...
