Evaluation of robot-assisted MRI-guided prostate biopsy: needle path analysis during clinical trials.
Physics in medicine and biology
Oct 16, 2018
While the interaction between a needle and the surrounding tissue is known to cause a significant targeting error in prostate biopsy leading to false-negative results, few studies have demonstrated how it impacts in the actual procedure. We performed...
Robotically Assisted CBCT-Guided Needle Insertions: Preliminary Results in a Phantom Model.
Cardiovascular and interventional radiology
Oct 10, 2018
AIM: To compare robotic-assisted needle insertions performed under CBCT guidance to standard manual needle insertions.
Diagnostic performance of real-time robotic arm-assisted F-FDG PET/CT-guided percutaneous biopsy in metabolically active abdominal and pelvic lesions.
European journal of nuclear medicine and molecular imaging
Aug 30, 2018
PURPOSE: To evaluate the feasibility and diagnostic performance of F-FDG PET/CT-guided biopsy of abdominal and pelvic lesions with automated robotic arm (ARA) assistance.
A deep learning approach for real time prostate segmentation in freehand ultrasound guided biopsy.
Medical image analysis
Jun 1, 2018
Targeted prostate biopsy, incorporating multi-parametric magnetic resonance imaging (mp-MRI) and its registration with ultrasound, is currently the state-of-the-art in prostate cancer diagnosis. The registration process in most targeted biopsy system...
Assessment of the Diagnostic Accuracy of Biparametric Magnetic Resonance Imaging for Prostate Cancer in Biopsy-Naive Men: The Biparametric MRI for Detection of Prostate Cancer (BIDOC) Study.
JAMA network open
Jun 1, 2018
IMPORTANCE: Multiparametric magnetic resonance imaging (MRI) enhances detection and risk stratification for significant prostate cancer but is time-consuming (approximately 40 minutes) and expensive. Rapid and simpler (approximately 15-minute) bipara...
Effective deep learning training for single-image super-resolution in endomicroscopy exploiting video-registration-based reconstruction.
International journal of computer assisted radiology and surgery
Apr 23, 2018
PURPOSE: Probe-based confocal laser endomicroscopy (pCLE) is a recent imaging modality that allows performing in vivo optical biopsies. The design of pCLE hardware, and its reliance on an optical fibre bundle, fundamentally limits the image quality w...
Evaluation of a CT-Guided Robotic System for Precise Percutaneous Needle Insertion.
Journal of vascular and interventional radiology : JVIR
Apr 6, 2018
PURPOSE: To assess overall targeting accuracy for CT-guided needle insertion using prototype robotic system for common target sites.
Computer-aided system for diagnosing thyroid nodules on ultrasound: A comparison with radiologist-based clinical assessments.
Head & neck
Dec 29, 2017
BACKGROUND: The purpose of this study was to compare the diagnostic efficiency of a thyroid ultrasound computer-aided diagnosis (CAD) system with that of 1 radiologist.
High-Risk Breast Lesions: A Machine Learning Model to Predict Pathologic Upgrade and Reduce Unnecessary Surgical Excision.
Radiology
Oct 17, 2017
Purpose To develop a machine learning model that allows high-risk breast lesions (HRLs) diagnosed with image-guided needle biopsy that require surgical excision to be distinguished from HRLs that are at low risk for upgrade to cancer at surgery and t...
Computed tomography (CT)-compatible remote center of motion needle steering robot: Fusing CT images and electromagnetic sensor data.
Medical engineering & physics
May 13, 2017
Lung cancer is the most common cause of cancer-related death, and early detection can reduce the mortality rate. Patients with lung nodules greater than 10 mm usually undergo a computed tomography (CT)-guided biopsy. However, aligning the needle with...
