Abstract: A helmet is disclosed including: a helmet body; a jaw guard with two fork handles through which the jaw guard is mounted on the helmet body and rotatable around a fixed axis relative to the helmet body; a shield assembly including a shield and a bracket, which is movable between a lowered position and a raised position relative to the helmet body; and a lifting mechanism including a trigger located beside the bracket of the shield assembly and driven by the fork handles of the jaw guard, and the trigger can touch the bracket of the shield assembly at the lowered position and raise the shield assembly from the lowered position. The lifting mechanism further includes an elastic element with one end connected with the bracket, which is arranged to make the shield assembly continue to move to the raised position after the shield assembly leaves the lowered position.

Abstract: An image segmentation system is discloses that provides one or more possible contours of a feature of an image, in parallel, that respectively correspond to different interpretations of the image. First, a relatively large set of possible contours are generated in accordance with an image segmentation algorithm. Subsequently, this set of possible contours is reduced to a few candidates reflecting representative solutions corresponding to one or more desired applications.

Abstract: A method for localizing a fiducial marker in a medical image includes: obtaining the medical image; and performing an analysis, using an analysis unit, to localize the fiducial marker in the medical image; wherein the fiducial marker is localized by the analysis unit without use of a marker template.

Abstract: A system and method for converting radiation therapy information into another form, the converted radiation therapy information being placed in a format such that it can be stored in any storage system, including PACS storages systems, irrespective of the implementation of DICOM; the converted radiation therapy information being expressed in a manner that is proportional/equivalent to a standard imaging parameter for CT or PET.
