Purpose: Imaging of patient anatomy during treatment is a necessity for position verification and adaptive radiotherapy based on daily dose recalculation. Ultrasound (US) image guided systems are currently available to collect US images at the simulation stage (US sim ), coregistered with computed tomography (CT), all fractions. The authors hypothesize that deformation field derived from US‐based deformable registration can be used create pseudo‐CT (CT ps ) more representative patients’...
The management of the cardio-respiratory motion target and reduction uncertainties related to patient's positioning are two main challenges that stereotactic arrhythmia radio-ablation (STAR) has overcome. A prototype a system was developed can automatically acquire interpret echocardiographic images using an artificial intelligence (AI) algorithm calculate cardiac displacement in real-time. We conducted single center study enrolling consecutive patients with history ventricular arrhythmias...
Abstract Cardiac radioablation is a promising treatment for cardiac arrhythmias, but accurate dose delivery can be affected by heart motion. For this reason, real-time motion monitoring during of paramount importance. Real-time ultrasound (US) guidance solution. The US-guided workflow simplified the simultaneous US and planning computed tomography (CT) acquisition, which result in transducer-induced metal artifacts on CT scans. To reduce impact these artifacts, new artifact reduction (MAR)...
Knee arthroscopy is a complex minimally invasive surgery that can cause unintended injuries to femoral cartilage and/or post-operative complications.Autonomous robotic systems using real time volumetric ultrasound (US) imaging guidance hold potential for reducing significantly these issues and improving patient outcomes.To enable the system navigate autonomously in knee joint, should provide robot with real-time comprehensive map of surgical site.To this end, first step automatic image...
The purpose of this study was to evaluate eight possible approaches create pseudo-CT images for radiotherapy (RT) treatment re-planning. These re-planning CT scans would normally require a separate scan session. If important changes occur in patient's anatomy between simulation (SIM) and (TX) stages, 3D ultrasound (US) acquired at the two available US guided RT workflows, can be used produce deformation field. Proof concept research showed that application field SIM image yields which more...
Image interpretation is crucial during ultrasound image acquisition. A skilled operator typically needed to verify if the correct anatomical structures are all visualized and with sufficient quality. The need for this one of major reasons why presently not widely used in radiotherapy workflows. To solve issue, we introduce an algorithm that uses information derived from a CT scan automatically provide patient-specific probe setup. first application investigated, its relevance radiotherapy,...
Cardiac stereotactic body radiotherapy is a promising noninvasive treatment for patients with refractory ventricular tachycardia. With the aim to prove feasibility of novel image guided and heart motion gating device, cardiac proton was performed using porcine model. Using adaptation γ - H2AX tissue staining techniques, we have been able localize radiation beam in large animal assess targeting accuracy within defined field. Cardiorespiratory-gated irradiations animals were successfully...
The use of ultrasound imaging is not widespread in prostate cancer radiotherapy workflows, despite several advantages (eg, allowing real-time volumetric organ tracking). This can be partially attributed to the need for a trained operator during acquisition and interpretation images. We introduce evaluate an algorithm that propose patient-specific transperineal probe setup, based on CT scan anatomical structure delineations. this setup simulation treatment stage could improve usability...
In US-guided cardiac radioablation, a possible workflow includes simultaneous US and planning CT acquisitions, which can result in transducer-induced metal artifacts on the scans. To reduce impact of these artifacts, artifact reduction (MAR) algorithm has been developed based deep learning Generative Adversarial Network called Cycle-MAR, compared with iMAR (Siemens), O-MAR (Philips) MDT (ReVision Radiology), CCS-MAR (Combined Clustered Scan-based MAR). Cycle-MAR was trained supervised scheme...
In many medical fields, spatial localization of devices is paramount importance to e.g. deliver treatments correctly or perform accurate diagnostic evaluations. Among the different technologies available, optical in visible band spectrum offers advantages: minimum interference with other instruments, flexibility position used and extra features such as patient/operator surface tracking vital signs monitoring. Its application domain radiotherapy novel, potentially very beneficial. this work...
Ultrasound imaging is one of the image modalities that can be used for radiation dose guidance during radiotherapy workflows prostate cancer patients. To allow acquisition treatment, ultrasound probe needs to positioned on body patient before delivery starts using e.g. a mechanical arm. This an essential step, as operator cannot present in room when beam turned on. Changes anatomical structures or small motions compromise quality, due loss acoustic coupling sudden appearance shadowing...
Purpose: The use of ultrasound (US) imaging in radiotherapy is not widespread, primarily due to the need for skilled operators performing scans. Automation probe positioning has potential remove this and minimize operator dependence. We introduce an algorithm obtaining a US position that allows good anatomical structure visualization based on clinical requirements. first application 4D transperineal images prostate cancer patients. Methods: calculates orientation using information provided...
