Abstract: A method for creating or evaluating a radiation shield for a radiation therapy treatment can include receiving, using one or more computing devices, three-dimensional (3D) imaging data, generating, using the one or more computing devices, a 3D volume of a portion of patient from the 3D imaging data, determining, using the one or more computing devices, a region of interest for receiving radiation therapy for the 3D volume of the portion of the patient, generating, using the one or more computing devices, a 3D model of a radiation shield from the 3D volume of the portion of the patient and the region of interest, the 3D model having an inner surface that contours an exterior surface of the 3D volume, and causing, using the one or more computing devices, a 3D printer to construct a radiation shield from the 3D model of the radiation shield.

Abstract: Described here is a phantom for use in quality assurance (“QA”) of a radiation treatment system, such as a linear accelerator (“LINAC”). The QA phantoms described in the present disclosure enable the implementation of a number of different technical standards with a single phantom. For instance, the QA phantom described in the present disclosure can replace five separate pieces of equipment and four unique setups with a single phantom and a single setup. To this end, the QA phantom can be referred to as a single alignment assorted procedures (“SNAP”) phantom.

Abstract: Purchase rewards account holders accumulate rewards currency. A network-based investment management system allows account holders to purchase shares in investments using reward currency. When all the shares for a particular investment have been purchased, the underlying investment is acquired. Account holders owning shares in an investment may sell shares to other account holders through system. Account holders are thereby able to invest their rewards dollars in investments typically requiring cash or cash equivalents and to grow their rewards currency.
