Multiple doping of CsI:Tl crystals and its effect on afterglow.

Despite the acknowledged advantages of CsI:Tl in many scintillator applications, a characteristic property that undermines its use in high-speed radiographic and radionuclide imaging is the presence of a strong afterglow component in its scintillation decay. This causes pulse pileup in high count-rate applications, reduced energy resolution in radionuclide imaging, and reconstruction artifacts in computed tomography applications. The research outlined here addresses the specific issue of suppressing the afterglow in CsI:Tl crystals by modifying them with codopants.

Development and remodeling of the hip joint of preterm neonates in sonographic evaluation.

Background. Recent studies on the developmental dysplasia of the hip emphasize the role of the last trimester of pregnancy in the origin of the pathology. The aim of the study was to evaluate the development of the hip joints of preterm neonates born with different weight and in different periods of pregnancy.

Proposed standards for prevention and early treatment of congenital dislocation of the hip.

Congenital dislocation of the hip is still most frequent fault of locomotive system in Poland. The level of prevention and treatment of this foult in Poland is differ from the same situations in other countries.
The paper presents the proposition for the standards for prevention and treatment of the congenital dysplasia of the hip.

A proposal for the radiological evaluation of treatment outcome in developmental dislocation of the hip and the classification of results.

The present study describes and analyzes current methods of evaluation of the morphology of the dysplastic hip found in the literature. The authors own method of evaluation is presented, which is based only on measurable parameters, and provides an objective and comparable definition of all the elements of which the joint is composed. The classification presented here enables the complete description of the morphology of the hip joint: the acetabulum, the proximal femur, the congruity of the joint, and the shape of the femoral head.
