IMRT Optimization with Both Fractionation and Cumulative Constraints
Radiation therapy plans are optimized as a single treatment plan, but delivered over 30 50 treatment sessions (known as fractions). This paper proposes a new mixed-integer linear programming model to simultaneously incorporate fractionation and cumulative constraints in Intensity Modulated Radiation Therapy (IMRT) planning optimization used in cancer treatment. The method is compared against a ...
متن کاملAltered fractionation for head and neck cancer.
A conventional course of radiation for squamous cell carcinoma in the United States is generally 70 Gy in 7 weeks, with a once-daily dose of 1.8 to 2 Gy. This schedule has a modest success rate in curing head and neck cancer. The past several decades have seen numerous investigations into altering this schedule to optimize the results of radiation. Two approaches, founded on radiobiologic princ...
متن کاملAltered Fractionation for Head and Neck Cancer
Delivery of therapeutic radiation in multiple sessions, or fractions, has been practiced since the discovery of radiation’s potential to cure malignancies. Initially, this was done out of practical necessity: Radiation was delivered at a low dose rate, and the treatment sessions had to be repeated to obtain the desired effect. Technologic improvements eventually allowed for treatments in one se...
متن کاملCombining Product Line Engineering with Options Thinking
Developing a product family in an uncertain environment where future family members cannot be reliably predicted generally implies high risk for a product line approach. As managers usually tend to favour short term and low risk projects, such a product family is not likely to be engineered as a product line. However, we can engineer different evolutionary paths of a product that are uncertain ...
متن کاملCombining different access options for image databases
Living Memory is an interdisciplinary project running for two years, which is realised in cooperation of several institutions. It aims at developing an information system for a digital collection of different types of visual resources and will combine classical methods of image indexing and retrieval with innovative approaches like content-based image retrieval and the use of topic maps for sem...
