The failure of x-ray diagnostic techniques to accurately detect tumors and other regions of abnormal density in soft tissue has been, for many years, a significant shortcoming of this important technique in medicine. Accelerated heavy particles with plastics for track detection can be used to record small differences in density in soft tissues which may correspond to biological structures and a...

Abstract Revolution in X-Ray OpticsThe past half-decade has witnessed a technological revolution in our abilityto generate, control , manipulate, focus, and detect x rays. The emergence ofx-ray lasers and synchrotron insertion devices has increased the brightness oflaboratory x-ray sources eight to twelve orders of magnitude. Also, significantadvances have occurred in th...

Blurry organ boundaries and soft tissue structures present a major challenge in biomedical image restoration. In this paper, we propose a low-rank decomposition-based method for computed tomography (CT) image sequence restoration, where the CT image sequence is decomposed into a sparse component and a low-rank component. A new point spread function of Weiner filter is employed to efficiently re...

We present X-ray and optical data of the newly discovered AM Her variable RX J1802.1+1804. This X-ray source was observed in the ROSAT All-Sky-Survey in September 1990 and subsequently discovered as a highly variable and soft X-ray source. Follow-up pointed observations confirmed the strong variability and revealed a periodic flux modulation including a sharp and nearly complete eclipse of the ...

A 5-year-old girl with right exophthalmos and esotropia presented to ophthalmology outpatient clinics. Orbital computed tomography revealed a 20- to 30-mm oval soft tissue mass lying superolateral to the right lateral rectus muscle in the orbit. The patient was operated on by a neurosurgical team, the csyt was removed totally, and examination of the pathologic specimen, which reveals the epider...

The soft tissues covering the face play an important role in facial aesthetics, speech and function. Detailed soft tissue analysis is an important component of comprehensive diagnosis and treatment planning. A balance between the dental and the perioral muscles must be achieved to attain stability of the treatment outcome. The aim of the study was to compare soft tissue facial profile between s...
