time of the symposium. Thus this work represents a review of the field as it stood then, rather than a collection of original research, for which its format of rapid offset printing is usually reserved. So although the book is a useful single source, it is rather unhappily organized to serve as an introduction to frozen blood for the uninitiated. The most useful and novel contributions are the ...

The determination of the propagation conditions of time-variant mobile radio channels is a main task in mobile communication systems. For systems based on CDMA, it is generally assumed that the receiver knows the corresponding spreading sequence. Therefore, this sequence can be used for a correlative channel estimation. This paper considers several concepts for the channel estimation in direct-...

A detailed analysis of the coronal anatomic and CT appearances of the orbital apex is presented. In cadavers, coronal CT 9800 scans of the orbital apex and precisely corresponding cryomicrotomic sections were obtained. The CT appearance of the optic nerve, anulus of Zinn, and cranial nerves III-VI at the superior orbital fissure and orbital apex were determined. These anatomic structures were a...

Critical to the understanding of data is the ability to provide pictorial or visual representations of those data, particularly in support of correlative data analysis. Despite the advancement of visualization techniques for scientific data over the last several years, there are still significant problems in bringing today's hardware and software technology into the hands of the typical scienti...

Microscopic techniques allow to investigate samples based on various contrasts such as optical, electron or magnetic. Although specialized microscopic techniques often yield convincing and sufficient information, there are many systems where just one kind of contrast does not give the whole picture and needs complementary technique. A well-known example is the combination of electron and optica...

A new study mapping the functional effects of brain lesions has revealed a surprising map of human intelligence, stimulating a re-evaluation of data from purely correlative methods such as functional magnetic resonance imaging.

Vertebral artery dissection after neck manipulation has been well described. A case of bilateral vertebral artery dissection diagnosed with dynamic CT scanning of the neck is reported. The CT appearances and correlative angiographic and MR findings are presented.
