Tervisetehnoloogiate hindamise arendamisest ja tulevikust Euroopas ja Eestis

TTH kui tegevusvaldkond on viimase 20 aasta jooksul olnud aktuaalne nii Euroopas kui ka kogu maailmas. TTH põhieesmärk on pakkuda tervisepoliitika ja praktika otsustusprotsessile tõenduspõhist alust, tagades olemasolevate ressursside otstarbekohase kasutamise. TTH arendamine Eestis koostöös FINOHTA, DACEHTA ning teiste Euroopa institutsioonidega on Eesti tervishoiusüsteemile heaks väljakutseks ning võimaluseks. Eesti Arst 2008; 87(6):456−46

Registrering af trængsel med Bluetooth

Bluetooth anvendes til radiokommunikation over korte afstande i mobiltelefoner, bilradioer, headsets og laptops. Denne artikel beskriver, hvordan Bluetooth kan anvendes til at registrere trængsel og til beregning af den gennemsnitlige strækningshastighed for biltrafik. Fordelen ved at anvende Bluetooth, sammenlignet med andre målemetoder, er lave implementerings- og driftsomkostninger til måleudstyret og infrastrukturen. Målinger lavet i Danmark af KeyResearch viser, at mellem 5 % - 18 % af alle biler har registrerbare Bluetooth- enheder ombord. Selvom denne procent er relativt lav, dokumenterer denne artikel, at det er nok til at registrere trængsel og strækningshastigheder i realtid

Measurements of Kinematic Properties of the Cervical Spine Using Magnetic Resonance Imaging

This paper presents kinematic data on the cervical and upper thoracic spine, based on measurements made on 20 Scandinavian healthy, female volunteers, aged 22-58 years (mean age 40.4). The aim was to provide anatomical in vivo data, primarily intended as data for biomechanical modelling of the upper spine. Together with the measurements of standard anthropometric body dimensions, magnetic resonance imaging (MRI) was used to capture the inner anatomy for each subject. A rigid linkage system is described for the vertebrae C1 –Tvi, with one link per vertebra. Measurements include link lengths, link rotations, and antero-posterior endpoints of the spinous process. Furthermore, correlation coefficients are calculated between link lengths and anthropometric measurements. Also presented are regression equations for each link length, with stature as a predictor. Using additional images of lower accuracy, a sub-study (N=15) investigated possible differences in link length and link rotation between non-flexion and maximum-flexion of the neck. The differences in link lengths were significant (p>0.05) for only 1 of 16 measured links (Cii-Tx). Regarding link rotation, differences were significant for 4 links (Cv–T1). Finally, the precision of the results was evaluated using two methods: by using a phantom for determining the geometrical uncertainties caused by the scanner; and by comparing results between two repeated measurement rounds. The phantom test revealed that the pixel resolution and magnetic field inhomogenities had only a minor influence on the results. The comparisons of repeated measurements revealed a significant difference for the links Ci and Cii, indicating that the landmarks for determining the occipital and Ci/Cii joints were the most difficult to identify on the images
