20110258117 | MODIFICATION OF PAYMENT TRANSACTIONS IN REAL-TIME BASED UPON EXTERNAL DATA SOURCE - A system for, and method of using multiple data flows, both transactional and non-transactional, in real time to modify a transaction is disclosed. Further the use of transaction information in real time as a decision factor to trigger a different, non-transactional response, and the combination of the two approaches is disclosed. In particular, a network comprised of a plurality of software modules and databases is capable of combining current POS/POP transaction data, with a variety of other outside data sources to provide improved information for adjusting responses to transactions in real time. More specifically, the network utilizes payer facing systems to analyze the data in combination with well-known POS/POP transaction data and a variety of internal and external systems to combine information and provide modified transactions, related discounts and offers, and other relevant messaging to the payer. In addition, a specific method for analyzing for fraud within hybrid information transactions is disclosed and several examples to illustrate the invention are included. | 10-20-2011 |
20120016728 | PROCESSING NON-TRADITIONAL TRANSACTIONS ON A TRADITIONAL PAYMENT NETWORK - A system for and methods of processing non-traditional payment transactions on a traditional payment network is disclosed. More specifically, a payments system includes one or more payment program managers (PPMs), which are the providers of alternative payment products, in combination with one or more payment program processors (PPPs), which serve as processors for the PPMs. The PPMs and PPPs operate on a payment network, such as a traditional payment network. The payments system includes the utilization of traditional bank identification numbers (BINS) in order to process non-traditional transactions on a traditional payment network. Surrogate numbers are issued on BIN ranges to the non-traditional transactions in order to process them on the traditional payment network. Additionally, the payments system includes pricing structures that are associated with alternative payment products. These pricing structures are implemented and processed on the payment network, alongside the pricing structures of traditional payment products. | 01-19-2012 |

20100150309 | REAL TIME TREATMENT PARAMETER ALGORITHM FOR MOVING TARGETS - A method of determining a treatment parameter, includes determining an accumulated dose at a target region that undergoes motion, determining an accumulated dose at a critical region, and determining the treatment parameter based on the determined accumulated dose at the target region and the determined accumulated dose at the critical region, wherein the act of determining the treatment parameter is performed during a treatment session. A method of determining a treatment parameter, includes tracking a position of a target, delivering radiation to the target based on the tracked position, and compensating for an inaccuracy of the tracked position by using information regarding a delivered dose to determine a treatment parameter for a next beam delivery. | 06-17-2010 |
20110293071 | METHOD FOR CALCULATING HEAD SCATTER PHASE SPACE FOR RADIATION TREATMENT USING A MULTI-LEAF COLLIMATOR WITH DYNAMIC JAWS - A method is proposed for accurate and efficient modeling of head scatter phase space for treatments with dynamic jaws. Specifically, the method enables the efficient calculation of the head scatter phase space in case of a dynamic treatment where jaws and MLC leaves move during the delivery. In one embodiment, the invention can be used to calculate the head scatter contribution during final dose calculation of dynamic treatments. This novel method also enables an accurate calculation of the head scatter contribution from optimal fluence and from jaw positions without having to calculate the leaf sequence. In this embodiment, the invention can be used in optimization of large field IMRT treatments. | 12-01-2011 |

20110091014 | Dose Calculation Method for Multiple Fields - Systems and methods for developing a treatment plan for irradiating a treatment volume within a patient are disclosed. In accordance with the present invention, control points used to calculate a dose of radiation delivered to the treatment volume may be combined to result in a smaller number of control points. The smaller number of control points may allow more efficient calculation of dose distributions resulting in a treatment plan that can be delivered to the patient earlier or may allow additional iterations of treatment plan optimization resulting in a more accurate dose distribution being delivered to the patient. | 04-21-2011 |
20140044236 | DOSE CALCULATION METHOD FOR MULTIPLE FIELDS - Systems and methods for developing a treatment plan for irradiating a treatment volume within a patient are disclosed. In accordance with the present invention, control points used to calculate a dose of radiation delivered to the treatment volume may be combined to result in a smaller number of control points. The smaller number of control points may allow more efficient calculation of dose distributions resulting in a treatment plan that can be delivered to the patient earlier or may allow additional iterations of treatment plan optimization resulting in a more accurate dose distribution being delivered to the patient. | 02-13-2014 |

20080285719 | Leaf sequencing - Systems and methods of controlling the leaves of an aperture in radiation treatment are disclosed. In some embodiments, these systems and methods allow the delivery of different radiation fluences to different parts of a treatment volume in a single rotation of the aperture around the treatment volume. In some embodiments, different radiation fluences are achieved by radiating different parts of the treatment volume from opposing positions of the aperture around the treatment volume. In some embodiments, different radiation fluences are achieved by assigning different leaf pairs to radiate different parts of the treatment volume. | 11-20-2008 |
20090082608 | Calculation of probable accumulated dosages based on patient movement - A stochastic patient movement model and a dosage delivery plan are used to determine probabilities of dosages received by a target volume during a radiation treatment. The stochastic patient movement model is created by identifying possible sequences of patient positions during the treatment with probabilities specified for each. The dosage delivery plan specifies dosage levels and radiation locations over time. Accumulated dosages are calculated for each sequence of patient positions and the dosage delivery plan. The specified probability for each sequence is then correlated to the accumulated dosage for that sequence. | 03-26-2009 |
20100046713 | LEAF SEQUENCING ALGORITHM FOR MOVING TARGETS - A method of providing intensity modulated radiation therapy to a moving target is disclosed. The target moves periodically along a trajectory that is projected onto a multi-leaf collimator (MLC) plane. The MLC plane is divided into thin slices parallel to the movement of the target. The present invention optimizes the leaf sequence such that, within each slice, if a point receives radiation, all other points in that slice that receive the same amount or more fluence are also receiving radiation at the same time. | 02-25-2010 |
