Using the CustusX toolkit to create an image guided bronchoscopy application: Fraxinus
Conclusions: The CustusX platform facilitates development of new and specialized applications. The toolkit supports the process and makes important extension and injection points available for customization....
Pulmonologist evaluation on new CT visualization for guidance to lung lesions during bronchoscopy
Translator disclaimer Full Article Figures & data References Citations Metrics Reprints & Permissions Get access Abstract Objective: Endoluminal visualization in virtual and video bronchoscopy lacks information about the surrounding structures, and the traditional 2 D axial, corona...
Laboratory test of Single Landmark registration method for ultrasound-based navigation in laparoscopy using an open-source platform
Purpose Test the feasibility of the novel Single Landmark image-to-patient registration method for use in the operating room for future clinical trials. The algorithm is implemented in the open-source platform CustusX, a computer-aided intervention research platform dedicated to intraoperative navig...
Manually steerable catheter with improved agility
Purpose: A prototype steerable catheter was designed for endovascular procedures. This technical pilot study reports the initial experience using the catheter for cannulation of visceral arteries. Technique: The 7F catheter was manually steerable with operator control handle for bending and rotation...
Navigated retrograde endoscopic myotomy (REM) for the treatment of therapy-resistant achalasia
Background In achalasia, muscle spasm may involve the proximal esophagus. When the muscle spasm is located in the proximal esophagus, conventional per oral endoscopic myotomy (POEM) may not be sufficient to relieve symptoms. In this paper, we describe retrograde endoscopic myotomy (REM) as a novel a...
Navigated Retrograde Endoscopic Myotomy (REM) for the Treatment of Therapy-Resistant Achalasia
Electromagnetic navigation versus fluoroscopy in aortic endovascular procedures: a phantom study
Purpose To explore the possible benefits of electromagnetic (EM) navigation versus conventional fluoroscopy during abdominal aortic endovascular procedures. Methods The study was performed on a phantom representing the abdominal aorta. Intraoperative cone beam computed tomography (CBCT) of the phant...
Registration of Real-Time 3-D Ultrasound to Tomographic Images of the Abdominal Aorta
The purpose of this study was to develop an image-based method for registration of real-time 3-D ultrasound to computed tomography (CT) of the abdominal aorta, targeting future use in ultrasound-guided endovascular intervention. We proposed a method in which a surface model of the aortic wall was se...
