Pliable diagnostic findings, e.g. canalicular optic neuritis and ?ther peripheral neuritis, rheumatoid arthritis, neurasthenia, Cental depression and even insanity. The existence of frontal sinusitis in doubtful cases may dually be diagnosed by means of good skiagrams and ^rther corroborated by passing a fine cannula into the sinus blowing air so as to cause any secretion from the sinus *? appe...

This paper presents an enhanced transillumination radiosity method that can provide accurate solutions at relatively low computational cost. The proposed algorithm breaks down the double integral of the gathered power to an area integral that is computed analytically and to a directional integral that is evaluated by quasi-Monte Carlo or Monte-Carlo techniques. The paper also analyses the requi...

THE viewing of translucent structures by transmitted light is a well established practice in ophthalmology, but so far does not seem to have been applied to the region of the angle of the anterior chamber. A simple and effective method of transillumination has been devised, and, as certain structures in this important region show to better advantage under these conditions, the technique is pres...

Methods: Spectral-domain OCT imaging was performed on study subjects in 3 groups: subjects with ocular albinism (OA) or suspected OA with foveal hypoplasia, with nystagmus, and with or without iris transillumination; a subject with oculocutaneous albinism and Hermansky-Pudlak syndrome; and control subjects. Dense volumetric scans of each fovea were captured using standard and handheld spectral-...

We demonstrated the separation of the component spatial patterns of chemical samples in transillumination terahertz ~THz! images using known spectral curves. The images and spectral data were measured between 1.3 and 1.8 THz, using a widely tunable coherent THz-wave parametric oscillator source. This method could be effective for analyzing spatial patterns and the concentrations of components w...

A 30-year-old woman presented with dilated episcleral vessels in the right eye which were found to be associated with an underlying ciliary body tumour. Contact lens examination, transpupillary transillumination, ultrasonography, computerised tomography, magnetic resonance imaging, and fine needle aspiration biopsy produced apparently conflicting and inconclusive results, and the eye was enucle...

A technique for inserting radial artery catheters percutaneously in newborn babies using transillumination is described. Catheterisation was successful in 69% of the 107 babies in whom it was attempted. In the last 30 attempts there was an 85% success rate with an average useful life of 100 hours. The average weight of these babies was 1405 g, with a range of 620--4250 g. The method has several...

This paper gives an overview of techniques for the investigation of the laryngeal devoicing gesture, discussing methodological issues relevant to the ensuring reliability and interpretability of the data. The emphasis is placed on fiberoptic filming and transillumination, as being the techniques most widely available in phonetics laboratories and probably most suitable for routine articulatory ...

Esophageal leiomyomas are the most common benign mesenchymal esophageal tumors, but they occur rarely in the pediatric population. Leiomyomas are conventionally treated with extramucosal enucleation via an open thoracotomy. In this paper, we report a case of a complex massive retrocardiac esophageal leiomyoma that was successfully extirpated by using a robotic-assisted thoracoscopic technique. ...
