[A review on the application of image fusion technology in prostate cancer radiotherapy based on gold fiducial biomarker].

Image fusion technology had been widely applied in image guided radiotherapy (IGRT) for prostate cancer (PCa) based on the gold fiducial mark (GFM). Image fusion technology included the fusion of CT image, magnetic resonance image, and ultrasound image internally or externally. The application of image fusion technology had improved the identification accuracy of GFM and was helpful for the plan design of PCa radiotherapy.

Two new benzophenones from endohydric moss .

Two new benzophenones ( and ), were isolated from the endohydric moss . Their structures were elucidated by spectroscopic methods including extensive 2 D NMR techniques. Compound is the first example of benzophenone with a rare cyclopropylacetamide from the natural resources.
