摘要： A method of delivering radiation treatment using multi-leaf collimation includes the step of providing a radiation fluence map which includes an intensity profile. The fluence map is converted into a preliminary leaf sequence, wherein the preliminary leaf sequence minimizes machine on-time and is generated without leaf movement constraints. The leaf movement constraint is imposed on the preliminary leaf sequence. At least one constraint elimination algorithm is then applied, the algorithm adjusting the preliminary leaf sequence to minimize violations of the constraint while providing the desired fluence map and minimized radiation on-time. The method can be applied to SMLC and DLMC systems, and can include adjustment for the tongue-and-groove effect.

摘要： A method of delivering intensity modulated radiation therapy (IMRT) is disclosed. An intensity profile for the treatment of a patient is provided which spans a prescribed field width and includes a discrete profile having intensity values at each of a plurality of sample points bounded by the prescribed width. The prescribed width is compared to a maximum field width provided by the radiation treatment system. The intensity profile is split into a plurality of intensity profile portions, each having respective widths less than the maximum width if the prescribed width is greater than the maximum width. The prescribed field is also divided into a plurality of different profile portion split arrangements. A monitor unit (MU) efficiency is calculated for each of the arrangements. One of the arrangements is selected for delivery by the system using a leaf sequencing method.

摘要： Ternary content-addressable memories (TCAMs) may be used to obtain a simple and very fast implementation of a router's forwarding engine. The applicability of TCAMs is, however, limited by their size and high power requirement. The present invention provides an improved method and associated algorithms to reduce the power needed to search a forwarding table using a TCAM. Additionally, the present invention teaches how to couple TCAMs and high bandwidth SRAMs so as to overcome both the power and size limitations of a pure TCAM forwarding engine. By using one of the novel TCAM-SRAM coupling schemes (M-12Wb), TCAM memory is reduced by a factor of about 5 on IPv4 data sets and by a factor of about 2.5 on IPv6 data sets; TCAM power requirement is reduced by a factor of about 10 on IPv4 data sets and by a factor of about 6 on IPv6 data sets.
