A study of the spatial distributions of the carbon blacks in polypropylene composites using TEM-Tomography and quantitative image analysis
It is well known that nanometer scale carbon materials such as carbon black (CB) and carbon nanotube were applied for filler of electron conductive polymer composites. However, it seems the knowledge of local ...

A study of the chain-folded lamellae structure and its array in the isotactic polypropylene spherulites by HAADF-STEM and HV-TEM Tomography techniques
It seems that the knowledge of the morphologies of chain-folded lamellae structure in the bulk crystalline polymers is limited, however, in industry, is out of necessary to understand increasing mechanical pro...

Clinical utility of synthesised brain surface imaging: Surface anatomy scanning and MR angiography
An MRI technique permitting direct, noninvasive display of brain surface structures (surface anatomy scanning, SAS) was developed using T2-weighted images. In this study, synthesised SAS, which combines contra...

The detectability of intracranial aneurysms using helical CT compared with conventional cerebral angiography
Helical CT (HCT) was applied to the diagnosis of cerebral aneurysms. The diagnostic accuracy of HCT, including the detectability of aneurysms, was compared with that of conventional cerebral angiography in 62 ...

Development and early trials of real-time CT fluoroscopy
A CT fluoroscopy system that permits real-time monitoring of CT images was developed. In phantom studies the images were displayed at a rate of 6 per s, with a delay time of 0.67 s. Early clinical trials in as...

Localization of cortical and subcortical lesions with MR brain surface imaging
A new MRI technique which permits non-invasive, direct visualization of cerebral sulci and gyri as well as cortical and subcortical lesions as a planar image is introduced. The usefulness of the technique in t...

Insertion Loss Reduction of InP Based Carrier-Injection-Type Optical S3 Switch
An 11dB insertion loss in a carrier-injection type 4 × 4 optical single- slip structure (S3) switch array is demonstrated by optimizing the waveguide structure and anti-reflection coating. To reduce further inser...

CT in Evaluation of the Circle of Willis
The method of visualizing the circle of Willis intentionally on contrast-enhanced CT scan was studied. The incidence of circle of Willis in our series was 86%. Only mild side effects were observed, in 7.5% of ...
