Download or read book Development of an Ultrasound based Image Guidance Radiotherapy System for Motion Management in the Liver written by Sydney Jupitz and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation therapy can be an effective treatment technique for liver tumors. However, the efficacy of radiotherapy is limited by the radio-sensitivity of healthy liver tissue. The risk of inducing negative side effects can be reduced by minimizing the mean liver dose. Respiratory motion can greatly impair the ability to reduce mean liver dose since tumors in the liver can move up to 30 mm. Therefore, motion management strategies are often needed to account for patient breathing motion during the radiotherapy treatments. An efficacious strategy to manage this is to model and monitor salient feature motion during treatment using image guidance techniques. Ultrasound offers a promising real-time, non-invasive and non-ionizing imaging solution for motion management. Our team developed the E4DL, a MR-compatible, 3D ultrasound transducer with hands-free operating capabilities. With this transducer, simultaneous ultrasound and MR image acquisition can be utilized for monitoring patient breathing motion during a pre-treatment imaging session. In this way we utilize the real-time capabilities of ultrasound while exploiting the complementary soft-tissue contrast mechanisms of ultrasound and MRI. This information can then be used to inform decisions during radiotherapy treatment under ultrasound-guidance alone, with the goal of minimizing treatment planning margins and sparing healthy liver tissue. The overall goal of this work was to develop a clinical workflow for an ultrasound-based image guided radiotherapy system utilizing the E4DL. To accomplish this, the image quality of the E4DL was benchmarked against commercial ultrasound probes with similar anatomically regional applications. Additionally, the image integrity of simultaneous ultrasound and MR acquisition was assessed. Overall, image quality was found suitable for the intended purpose of ultrasound image guidance for radiotherapy in the liver. Furthermore, image integrity and utility was not impacted by simultaneous ultrasound and MR acquisition. Following the image quality investigation, re-treatment imaging workflow feasibility was assessed with the recruitment and imaging of healthy volunteers with simultaneous ultrasound and MR acquisition. Liver vessel tracking was performed on these datasets for further analysis and workflow development. Utilizing the healthy volunteer imaging data, 3D ultrasound to MR registration and 4D MR reconstruction methods were established. These developments provide important information for treatment planning for ultrasound-guided radiotherapy. The registration provides the necessary transformation to convert the ultrasound vessel tracking results into the MR coordinate system, which can later be referenced to the linac coordinate system. The 4D MR reconstruction offers additional information for tumor deformation assessment throughout a typical breathing cycle. This work continues with a discussion of sources of uncertainty inherent to this workflow as well as reproducibility. Speed of sound, refraction, probe motion, interpolation, and tracking were all found to be potential sources of uncertainties relevant to this workflow. These were individually quantified and found to be less than 2 mm each. Reproducibility of probe placement was assessed in terms of distance-to-agreement of internal and external markers between repeated datasets from the healthy volunteer imaging study. These results could be improved with intentional workflow developments to facilitate probe replacement and ultrasound field of view alignment over multiple imaging sessions. Finally, this work concluded with the development of a 3D ultrasound to ultrasound image registration method. This registration is intended to transform real-time ultrasound feature tracking results back into the pre-treatment planning ultrasound coordinate system, which is referenced to the MR and linac coordinate systems. Overall, this work has made major strides to propelling this novel technology and system into the clinical workflow for ultrasound-based image guidance for liver radiotherapy.

Download or read book Registration of 3D Ultrasound Volumes with Applications in Neurosurgery and Prostate Radiotherapy written by Hang Zhou and published by . This book was released on 2017 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain tissue deforms significantly after opening the dura and during tumor resection, invalidating pre-operative imaging data. Ultrasound is a popular imaging modality for providing the neurosurgeon with real-time updated images of brain tissue. Interpretation of post-resection ultrasound images is difficult due to large brain shift and tissue resection. Furthermore, several factors degrade the quality of post-resection ultrasound images such as strong reflection of waves at the interface of saline water and brain tissue in resection cavities, air bubbles and the application of blood-clotting agents around the edges of resection. Image registration allows comparison of post-resection ultrasound images with higher quality pre-resection images, assists in interpretation of post-resection images and may help identify residual tumor, and as such, is of significant clinical importance. Prostate motion is known to reduce the precision of prostate radiotherapy. This motion can be categorized into intrafraction and interfraction. Interfraction motion introduces large systematic errors into the treatment and is the largest contributor to prostate planning treatment volume (PTV) margins. Conventional solutions to interfraction motion all have respective drawbacks. Clarity Autoscan system provides continuous ultrasound imaging of the prostate for interfraction motion correction, however it is time-consuming and can have large interobserver errors. The intension of accurately targeting the prostate and reducing the side effects in treatment requests a faster and more accurate registration framework for interfraction motion correction.In this thesis, we first propose a registration framework called Nonrigid Symmetric Registration (NSR) for accurate alignment of pre- and post-resection volumetric ultrasound images in near real-time. An outlier detection algorithm is proposed and utilized in this framework to identify non-corresponding regions (outliers) and therefore improve the robustness and accuracy of registration. We use an Efficient Second-order Minimization (ESM) method for fast and robust optimization. A symmetric and inverse-consistent method is exploited to generate realistic deformation fields. The results show that NSR significantly improves the quality of alignment between pre- and post-resection ultrasound images. Then based on this framework, we develop a rigid registration framework called Prostate Registration Framework (PRF) for alignment of the prosate region in simulation and treatment volumes. PRF is trained using 2 3D transperineal ultrasound (TPUS) images of an ultrasound prostate phantom and 20 3D TPUS images from 11 patients receiving Clarity Autoscan. Algorithm performance is evaluated using further 21 TPUS images from a total of 8 patients by comparison of the PRF with manual matching of landmarks and Clarity-based estimation of interfraction motion performed by three observers. The results show that PRF outputs more accurate alignment of the prosate region in simulation and treatment volumes than Clarity, and further, provides the reposition of the prostate in treatment images efficiently and accurately.
