BACKGROUND AND PURPOSE The pathophysiology of crossed cerebellar diaschisis (CCD) remains to be elucidated. In CCD, the metabolic suppression resulting from deafferentation may cause vasoconstriction, which may result in a decrease in cerebral blood volume (CBV) and may differentially affect the flows of red blood cells and of plasma. The purpose of this study was to investigate whether CCD dec...

The goal of the presented experiments is the development of new optical tracking techniques for space objects, namely space debris, based on simultaneous CCD and laser measurements: the CCD tracking of a laser illuminated object, the simultaneous CCD tracking and laser ranging and the laser time-tagging of the CCD tracking. The first two experiments can be performed on cooperative corner retro-...

Small format, medium resolution CCD cameras are at present widely used for industrial metrology applications. Large format, high resolution CCD cameras are principally used for scientific applications, but are slowly infiltrating photogrammetry and dramatically improving the object space accuracy achievable by close range measurement. The calibration of all types of CCD cameras is necessary in ...

AIM To investigate the quality of periapical radiographic images produced by two digital dental radiography systems, a charge-coupled device (CCD) and a photostimulable phosphor (PSP) image plate system, and to examine the overall radiation exposure when using these systems in a clinical setting. METHODOLOGY Patients were randomly allocated to both systems and the resultant radiographs rated ...

A practical imaging-based classification of cerebellar malformations distinguishes between focal and diffuse conditions, and between cerebellar hypoplasias and cerebellar dysplasias [1]; among the latter, an important subgroup is represented by cerebellar cortical dysplasias (CCD). CCD has been reported in association with chromosomal abnormalities, congenital muscular dystrophies, other suprat...

Cleidocranial dysplasia (CCD) is a rare autosomal dominant skeletal disease. CCD is caused by mutation in the gene on 6p21 encoding transcription factor CBFA1, i.e. runt-related transcription factor 2(RUNX2). The disease is characterized by a persistently open anterior fontanelle and skull sutures, hypoplastic or aplastic clavicles, dental abnormalities, short stature, a wide pubic symphysis, a...
