Radiation Oncology is one of the businesses that employs Machine Learning to automate quality assurance tests so errors and defects can be reduced, avoided, or eliminated as much possible during tumor therapy using a Linear Accelerator with MultiLeaf Collimator (Linac MLC). The majority applications have used supervised learning algorithms rather than unsupervised algorithms. However, in most c...

The purpose of this study was to measure the multileaf collimator (MLC) transmission from the first Hi-Art II tomotherapy machine installed at the Advanced Center for Treatment, Research, and Education in Cancer (ACTREC). The MLC transmission was measured with an A1SL ion chamber and the radiographic extended dose range (EDR2) film in virtual water slabs at 1.5-cm depth with a source-to-surface...

Radiation therapy treatment planning for many clinical situations requires wedgeshaped isodose distributions. The wedged dose distributions can be generated through the use of physical wedges (PWs), motorized wedges and the synchronization of jaw or multileaf collimator dynamic motion with accelerator dose output. Modern medical accelerators are usually equipped with a dynamic wedge (DW) option...

The application of intensity-modulated radiation therapy (IMRT) has enabled the delivery of high doses to the target volume while sparing the surrounding normal tissues. The drawbacks of intensity modulation, as implemented using a computer controlled multileaf collimator (MLC), are the larger number of monitor units (MUs) and longer beam-on time as compared with conventional radiotherapy. Addi...
