The first clinical treatment with kilovoltage intrafraction monitoring (KIM): A real-time image guidance method
Published 2015-01-01PURPOSE: Kilovoltage intrafraction monitoring (KIM) is a real-time image guidance method that uses widely available radiotherapy technology, i.e., a gantry-mounted x-ray imager. The authors report on the geometric and ...Open AccessArticle -
Breathing guidance in radiation oncology and radiology: A systematic review of patient and healthy volunteer studies.
Published 2015-09-01PURPOSE: The advent of image-guided radiation therapy has led to dramatic improvements in the accuracy of treatment delivery in radiotherapy. Such advancements have highlighted the deleterious impact tumor motion can ...Open AccessArticle -
An MRI-compatible patient rotation system — design, construction, and first organ deformation results
Published 2017-02-13PURPOSE: Conventionally in radiotherapy, a very heavy beam forming apparatus (gantry) is rotated around a patient. From a mechanical perspective, a more elegant approach is to rotate the patient within a stationary beam. ...Open AccessArticle -
Online 4D ultrasound guidance for real-time motion compensation by MLC tracking
Published 2016-10-01PURPOSE: With the trend in radiotherapy moving toward dose escalation and hypofractionation, the need for highly accurate targeting increases. While MLC tracking is already being successfully used for motion compensation ...Open AccessArticle -
Estimating lung ventilation directly from 4D CT Hounsfield unit values
Published 2016-01-01PURPOSE: Computed tomography ventilation imaging (CTVI) aims to visualize air-volume changes in the lung by quantifying respiratory motion in 4DCT using deformable image registration (DIR). A problem is that DIR-based ...Open AccessArticle
