Ultrasound based Respiratory Motion Compensation in the Abdomen
For image-guided interventions, the patient respiratory motion has to be considered when integrating pre-operative plans and imaging into the interventional suite. Ultrasound is particularly attractive for obtaining live information about anatomical changes, without adding further radiation dose to patient and physician such as fluoroscopy. We propose a strategy to both detect and compensate fo...
متن کامل[MRI/US-fusion for targeted prostate biopsy].
An innovative fusion of previously acquired magnetic resonance imaging (MRI) images with real-time transrectal ultrasound (US) may lead to improved prostate cancer detection, thus necessitating fewer biopsies. Suspicious lesions can be identified, localised - and possibly classified - via an MRI scan. Subsequently, a biopsy needle can be guided accurately into the suspicious area of the prostat...
متن کاملProstate biopsies guided by three-dimensional real-time (4-D) transrectal ultrasonography on a phantom: comparative study versus two-dimensional transrectal ultrasound-guided biopsies
OBJECTIVE This study evaluated the accuracy in localisation and distribution of real-time three-dimensional (4-D) ultrasound-guided biopsies on a prostate phantom. METHODS A prostate phantom was created. A three-dimensional real-time ultrasound system with a 5.9MHz probe was used, making it possible to see several reconstructed orthogonal viewing planes in real time. Fourteen operators perfor...
متن کاملMRI and ultrasound-guided prostate biopsy using soft image fusion.
OBJECTIVES Transrectal ultrasound (TRUS)-guided random biopsies is the gold standard when diagnosing prostate cancer. A new 3D system with organ tracking, allows accurate targeted biopsies using magnetic resonance imaging (MRI) and TRUS soft image fusion. The aim of the study was to evaluate the accuracy of targeted biopsies. MATERIALS AND METHODS Retrospective study of 90 consecutive patient...
متن کاملReal-time motion-adaptive-optimization (MAO) in TomoTherapy.
IMRT delivery follows a planned leaf sequence, which is optimized before treatment delivery. However, it is hard to model real-time variations, such as respiration, in the planning procedure. In this paper, we propose a negative feedback system of IMRT delivery that incorporates real-time optimization to account for intra-fraction motion. Specifically, we developed a feasible workflow of real-t...
