About this Research Topic
Management of tumor intra-fractional motion is essential for the safe and accurate delivery of radiotherapy. The patient's anatomy is continually moving during treatment delivery, and with increasing hypofractionation of radiotherapy, it becomes increasingly important to mitigate any systematic anatomical changes occurring during treatment delivery. Hardware, in the form of kV imaging, ultrasound transducers and MR imaging, as well as software have been developed for intra-fractional motion monitoring. Many of the existing systems have used external surfaces as a surrogate for the (internal) tumor, or fiducial markers implanted in or near the tumor, whereas newer systems enable direct visualization and monitoring of the tumor itself.
New motion management systems (MMS) such as those using cine MRs, along with the use of visual feedback systems for the patient, have recently become available. However, there is relatively little information available about the introduction and use of such systems. This Research Topic aims to provide guidance for the implementation and use of MMS, including establishing requirements for latency and accuracy, and to provide recommendations for medical physicists on the introduction and quality assurance of new systems. An overview of the systems currently available would also enable radiotherapy departments select systems and strategies that best suit the needs of the department.
We welcome authors to submit Original Research, Review, Mini Review and Case Reports articles with a primary focus on, but not limited to, the following sub-topics:
● Overview of MMS currently available;
● Implementation, commissioning and quality assurance of MMS;
● Initial clinical experience with new systems;
● Guidelines for use of MMS, with specific focus on respiratory versus non-respiratory motion.
Please note: Manuscripts consisting solely of bioinformatics or computational analysis of public genomic or transcriptomic databases which are not accompanied by validation (independent cohort or biological validation in vitro or in vivo) are out of scope for this section and will not be accepted as part of this Research Topic.
