20130114741 | SIGNALING OF STATE INFORMATION FOR A DECODED PICTURE BUFFER AND REFERENCE PICTURE LISTS - Innovations for signaling state of a decoded picture buffer (“DPB”) and reference picture lists (“RPLs”). In example implementations, rather than rely on internal state of a decoder to manage and update DPB and RPLs, state information about the DPB and RPLs is explicitly signaled.

For example, an encoder determines state information that identifies which pictures are available for use as reference pictures (optionally considering feedback information from a decoder about which pictures are available). The encoder sets syntax elements that represent the state information. In doing so, the encoder sets identifying information for a long-term reference picture (“LTRP”), where the identifying information is a value of picture order count least significant bits for the LTRB.

Then, an image detector holder and detector may be moved up and down to different heights behind the shield, based on the height of the markers. A source of radiation provides images at the multiple image areas. The multiple image areas may be connected by aligning stitching markers that may be on the shield, and are in the images. The aligning may be done by an automated computer software process that recognized patient anatomy and/or the stitching markers. | 2013-05-09 |
20130114791 | Imaging Method with a Radiotherapy Device and Radiotherapy Device - A method for imaging with a radiotherapy device is provided. The radiotherapy device includes a movably mounted imaging apparatus with an X-ray source and an oppositely disposed X-ray detector. The method includes preparing a first image with the imaging apparatus from a first imaging direction. The imaging apparatus is moved to a position that permits the preparation of a second image from a second imaging direction extending at an angle to the first imaging direction. The method also includes preparing the second image with the imaging apparatus from the second imaging direction, and verifying the position of an object to be irradiated using the first image and the second image. | 2013-05-09 |
