Abstract: A method includes positioning a patient at a first orientation relative to a radiation source. The method further includes using a 3D imaging technique to measure one or more positions of the patient's chest. The method further includes, while using the 3D imaging technique to measure the one or more positions of the patient's chest: generating a model of the patient's chest using the one or more positions of the patient's chest; updating the model of the patient's chest as the patient breathes; and exposing the patient to a dose of radiation using the radiation source, wherein the dose is based on the model of the patient's chest.

Abstract: Systems and methods for positioning a patient during radiological measurements are provided. A biofeedback signal from the patient is received. While receiving the biofeedback signal from the patient and while the patient is positioned at a first position by the fixture, determining whether the biofeedback signal from the patient is indicative of the patient breathing at rest. Further, in accordance with a determination that the biofeedback signal from the patient is not indicative of the patient breathing at rest, articulating the patient using the fixture from the first position to a second position. In accordance with a determination that the biofeedback signal from the patient at the second position is indicative of the patient breathing at rest, obtaining radiological measurements of the patient with the patient positioned at the second position.

Abstract: A process for the preparation of graphene includes the steps of a) providing flash thermal treatment of a graphite oxide at a temperature up to 700° C. sufficient to produce exfoliation and under inert atmosphere and b) cooling the material obtained in the previous step below 90° C. The method further includes the step of c) heating the material resulting from the previous step under inert atmosphere at a temperature which is higher than the temperature of step a), wherein the heating rate is between 1 and 15° C./min. The graphenes obtained from the process exhibit excellent physico-chemical properties.

Abstract: A getter composition suitable for gettering hydrogen comprises a first metal oxide and a second metal oxide, said first metal oxide being more readily reducible in hydrogen at temperatures between 0° C. and 100° C. than said second metal oxide.
