Multileaf collimators (MLCs) are an essential component in modern radiotherapy that shape the X-ray treatment beam. Currently, MLC leaf position accuracy is verified to ±1 mm every month. However, leaf position accuracy can drift between verificatio

The current trend in X-ray radiotherapy is to treat cancers that are in difficult locations in the body using beams with a complex intensity profile. Intensity-modulated radiotherapy (IMRT) is a treatment which improves the dose distribution to the t

Monolithic Active Pixel Sensor (MAPS) devices are an effective tool for upstream verification of Intensity Modulated Radio Therapy treatments. It is crucial to measure with high precision the positions of the Multi Leaf Collimators (MLC) used to shap

Beyond dissociation logic: evidence for controlled and automatic influences in artificial grammar learning

Autor: P A, Higham, J R, Vokey, J L, Pritchard

Publikováno v: Journal of experimental psychology. General. 129(4)

Evidence for unconscious learning has typically been based on dissociations between direct and indirect tests of learning. Because of some inherent problems with dissociation logic, we applied the logic of opposition to 2 artificial grammar learning
