A feasibility study on deep learning‐based individualized 3D dose distribution prediction

Abstract: Purpose Radiation therapy treatment planning is a trial‐and‐error, often time‐consuming process. An approximately optimal dose distribution corresponding to a specific patient's anatomy can be predicted by using pre‐trained deep learning (DL) models. However, dose distributions are often optimized based not only on patient‐specific anatomy but also on physicians’ preferred trade‐offs between planning target volume (PTV) coverage and organ at risk (OAR) sparing or among different OARs. Therefore, it is desirabl… Show more

“…Since Nguyen pioneered the U-Net variant, more and more studies have focused on the DL developed based on 3D U-Net. By changing the internal structure of the model, it can be combined with different ML methods, such as DenseNet [41] , HD U-Net, DVHnet, and ResDevNet.Or by using various input data, such as distance information, PTV and OARs contour information, etc., with corresponding development in the fields of head and neck cancer [1] , [42] , [43] , [44] , [45] , [46] , [47] , [48] , breast cancer [49] , [50] , lung cancer [51] , [52] , prostate cancer [36] , [44] , [53] , [54] , [55] , [56] , [57] , [58] , [59] , and cervical cancer [60] , respectively.…”

“…Some systems that automate contouring, planning, and plan evaluation of less complex treatment plans, such as human breast, prostate, and GI cancers, include the Automated Treatment Planning Assistant developed by MD Anderson, and the automated planning system developed at the Princess Margaret Hospital 36–38 . Deep learning has also been applied in generating optimized treatment plans and predict dose distributions based on a given set of inputs such as gantry angles, weights, and multi‐leaf collimator (MLC) settings 39–41 …”

“…[36][37][38] Deep learning has also been applied in generating optimized treatment plans and predict dose distributions based on a given set of inputs such as gantry angles, weights, and multi-leaf collimator (MLC) settings. [39][40][41] Experience with MCO and knowledge-based planning have yet to be reported in veterinary radiation oncology, but these technologies are currently available in commercial treatment planning systems. As the number of cases normally used to train such systems in the human domain are typically on the order of a 100, developing, training, and validating such systems in the veterinary domain becomes challenging.…”
