Abstract: The present disclosure may disclose methods and systems for treating an object. The method may include imaging an object fixed on a positioning device using an imaging device. The method may include obtaining a plan image of the object. The method may include generating information of a region of interest (ROI) of the object based on the plan image of the object. The method may include generating a treatment plan based on the information of the ROI. The treatment plan may include a plan isocenter on the plan image. The method may further include treating a target portion of the object based on the treatment plan using a treatment device. The object may be fixed on the positioning device from a moment that the object is started to fixed on the positioning device to an end of the treatment of the target portion.

Abstract: Organic intermediate synthesis, and provides a method for light-promoted oxidation of a compound containing a saturated carbon-hydrogen bond, comprising mixing a compound containing a saturated carbon-hydrogen bond with a catalyst, and oxidizing the compound containing a saturated carbon-hydrogen bond in an oxygen or air atmosphere at a temperature of 20° C. to 100° C. under light irradiation to generate an oxidation product. A method for the light-promoted direct oxidation of a compound containing a saturated carbon-hydrogen bond, which only requires a relatively low temperature to be carried out, has good compatibility with functional groups, short reaction time, high reaction efficiency, low reaction costs, high added value, simple operation and good safety, and is a mild, green and environmentally friendly oxidation method.
