“…In online ART, the treatment plan is re‐optimized according to anatomical or positional changes in OARs on a daily basis, significantly improving the accuracy of radiation dose delivery and a substantial reduction in the irradiated volume of normal tissue. In this way, online ART facilitates local dose escalation and the reduction of normal tissue toxicities through real‐time, risk‐adaptive, and high‐precision radiotherapy …”

“…In this way, online ART facilitates local dose escalation and the reduction of normal tissue toxicities through real-time, risk-adaptive, and high-precision radiotherapy. [5][6][7][8] Despite the superior features of MRI compared to other image guiding modalities (e.g., CT or cone beam CT), it faces the persistent problem of limited spatial resolution. [9][10][11][12] High spatial resolution in MRI comes at the expense of longer scanning time, reduced field of view (FOV), and reduced signal to noise ratio (SNR).…”

“…Nowadays, most contour research only uses geometric indices to evaluate the acceptability of contouring results. With the aim of using an objective evaluation method (for geometric indices), it is generally believed that a DSC value greater than 0.7 means the contouring result is clinically acceptable [24][25][26][27], while for distance-type geometric indices (HD, HD mean , HD95), smaller values mean that the contouring result is clinically acceptable, and the closer the value is to zero, the better the contouring result is. However, this statement is ambiguous.…”

“…However, this statement is ambiguous. The article about the study of automatic segmentation of OARs showed that an (Liver) HD = 15.770 ± 1.0 mm had a high accuracy [27], while another article indicated that an HD = 37.7 ± 13.8 mm also showed a high accuracy [28].…”

“…ML algorithms have been developed to identify patients that may benefit from adaptive re-planning for head and neck cancer and prostate cancer (103)(104)(105). ML algorithms for online adaptive magnetic resonance guided radiotherapy have been developed for patients with gastrointestinal cancers in which a daily optimized plan is generated before each treatment based on changes in anatomy seen on the magnetic resonance imaging scan (35,106). Interested readers are referred to a detailed review on the role of machine learning in adaptive radiotherapy (107).…”
