Purpose: Evaluation of the added value of radiotherapy guided by the cutaneous   surface in the positioning and monitoring of the radiotherapy   Patients and Methods: This study included 21 consecutive patients treated with an   accelerator dedicated to "True Beam®" stereotactic radiotherapy whose sessions were   monitored by an Optical Surface Monitoring System: "OSMS®". Excluded from our   study were treatments controlled exclusively by radiological imaging (IGRT).   Positioning variabilities were compared between conventional imaging and skin   surface infrared (OSMS) monitoring. Conventional imaging was in the form of   standard radiography (KV) performed during the treatment session or three-   dimensional by a series of Cone Beam computerized tomography (CBCT) scanned   images made at the beginning and end of The total time of the session and   the positioning variability’s in the 3 planes were   14   Results: The results of our study show that the cutaneous surface monitoring allowed   to obtain a faster alignment of the patient with an improvement in the overall time of   the session with a mean at 32% [14.5-49.27%], likewise a sub-millimeter positioning   quality for all locations with a median longitudinal distance of 0.02 cm [0-0.66], 01   cm verticality [0-0.32] and laterality 0.02 cm [0-0.77] This benefit is significantly   greater for cerebral and Head and neck’s localizations   21   Conclusion: Optical Surface Monitoring System (OSMS®) is a non-invasive and non-   irradiating means that allows reliable and fast

Acquisition Method

Road surfaces should be maintained in excellent condition to ensure the safety of motorists. To this end, there exist various road-surface monitoring systems, each of which is known to have specific advantages and disadvantages. In this study, a smartphone-based dual-acquisition method system capable of acquiring images of road-surface anomalies and measuring the acceleration of the vehicle upon their detection was developed to explore the complementarity benefits of the two different methods. A road test was conducted in which 1896 road-surface images and corresponding three-axis acceleration data were acquired. All images were classified based on the presence and type of anomalies, and histograms of the maximum variations in the acceleration in the gravitational direction were comparatively analyzed. When the types of anomalies were not considered, it was difficult to identify their effects using the histograms. The differences among histograms became evident upon consideration of whether the vehicle wheels passed over the anomalies, and when excluding longitudinal anomalies that caused minor changes in acceleration. Although the image-based monitoring system used in this research provided poor performance on its own, the severity of road-surface anomalies was accurately inferred using the specific range of the maximum variation of acceleration in the gravitational direction.
