We aimed to compare a new laser-based three-dimensional (3D) measuring device with computer planimetry with photography for the assessment of venous lei ulcers. and to estimate the reliability of measurements by the methods. The precision and accuracy of the methods were determined and compared. "The accuracies for computer planimetry with photography in comparison with the laser-based 3D measuring method were 8,4% for perimeter and 16.0`% for area measurements.

Using microarray technology, a recent study identified a large number of significantly altered mRNAs in HD blood, from which a 12-gene set was selected as classifier for discriminating controls and HD patients.Four different subject groups were included-patients with HD, Parkinson's disease (PD), acute ischemic stroke (AS) and healthy controls. Predictive value of the selected biomarker set for HD group was 78%, with 82% sensitivity and 53% specificity. Further gene expression analyses in longitudinal studies are needed to validate and refine possible transcriptomic blood biomarkers in HD

An optical system for 3-D chest wall measuring during breathing is described. The system is based on a laser multiple-line triangulation technique. The accuracy is 0.5 mm, the measuring range is 400x600x500 mm and the frequency is 80 Hz. The system efficiency was testedby an adult volunteer, who was breathing in two regimes: rib-cage-dominant and abdomen-dominant. The results show the breathing patternin a graphical and numerical way.

In a prospective cohort study of 81 patients with venous leg ulcers, we used a laser-based three-dimensional measurement of the ulcers at days 0 and 28 to estimate the predictive power of horizontal (HIHR) and vertical initial healing rates (VIHR) for wound healing by week 24. The influence of risk factors on both the initial healing rates was also studied. Together with ulcer duration, they are independent predictors of the 24-week healing (the area under ROC curve equals to 0.9). VIHR gives us additional information and significantly improves the prediction of 24-week healing.

Optical three-dimensional shape measurement of live objects is becoming an important developing tool. The current methods are reaching truly high speed in one view configuration, but in the case of the entire object shape measurement, they are limited due to mutual interference between multiple measuring modules. The proposed method overcomes this limitation by using a laser multiple-line triangulation technique, where each of several measuring modules uses a unique laser wavelength. The results of the shape of a foot rising on its toes are given as an example.
