Abstract: The embodiments herein relate to methods, apparatus, and systems for forming and purifying solid carbon material from a molten carbonate salt electrolyte. Various embodiments also provide methods, apparatus, and systems for recycling certain materials including the carbonate salt electrolyte, carbon dioxide, water, etc. Advantageously, the system utilizes carbon dioxide in one or more processes, for example to purify the solid carbon and regenerate the carbonate salt electrolyte. These methods, apparatus, and systems provide an efficient technique to consume carbon dioxide in the production of solid carbon, with substantial advantages over systems that attempt to form solid carbon from a stream of carbon dioxide provided directly to an electrolysis reactor.

Abstract: A system and method for capturing a portal image using a linear accelerator having a multi-leaf collimator (MLC) and an imager allows the portal image field to be automatically clipped using the multi-leaf collimator so that the projection of the portal image field onto the imager falls within the allowed image area of the imager. In this manner, portal images may be obtained in instances where the projection of the portal image field onto the flat-panel imager is larger than an allowed image area of the imager, or where the projection of the portal image field onto the imager is not centered and would extend beyond the allowed image area, so that radiation sensitive electronics outside of the allowed image area are protected from undesirable exposure to radiation.

Abstract: An ultrasound system creates ultrasound images at faster frame rate by eliminating ultrasonic transmissions along every beam line. Preferably, ultrasound images are created by alternately transmitting ultrasonic signals on the even and odd transmit beam lines. Parallel beam forming is used where transmissions along a single transmit beam line create echo signals on a pair of receive beam lines. To eliminate the artifact caused by the round-trip beam line sensitivities, echo signals created in response to transmissions along the even transmit beam lines are averaged with echo signals created in response to transmissions on the odd transmit beam lines. The averaged echo signals are used to create an ultrasound image without artifacts.
