BACKGROUND The purpose of this study was to evaluate the feasibility of ultrasound-guided intratumoral indigo carmine injections for intraoperative localization of small head and neck tumors and to introduce our surgeon-performed technique. METHODS In total, 23 patients who had tumors ≤1.5 cm that were not palpable by 2 head and neck surgeons were enrolled in this prospective study. RESULTS...

A challenging goal of aircraft structural health monitoring (SHM) systems is to provide continuous assessment of structural integrity during flight. It is now widely recognized that variable environmental and operational conditions can compromise results and thus lead to erroneous maintenance and usage decisions. This issue is particularly evident for SHM systems utilizing ultrasonic guided wav...

OBJECTIVE Review surgical techniques and outcomes of ultrasound-guided, transfacial, gland-preserving removal of difficult parotid stones. STUDY DESIGN Case series with chart review. SETTING Two academic tertiary care centers. METHODS Patients who underwent ultrasound-guided, combined transfacial-endoscopic operation for symptomatic parotid sialolithiasis from June 2010 through June 2012 ...

The purpose of this study was to evaluate the accuracy of a two-dimensional (2D) to three-dimensional (3D) image-fusion-guided target localization system and a mask based stereotactic system for fractionated stereotactic radiotherapy (FSRT) of cranial lesions. A commercial x-ray image guidance system originally developed for extracranial radiosurgery was used for FSRT of cranial lesions. The lo...

In this paper, we introduce a novel problem of audio-visual event localization in unconstrained videos. We define an audio-visual event as an event that is both visible and audible in a video segment. We collect an Audio-Visual Event (AVE) dataset to systemically investigate three temporal localization tasks: supervised and weakly-supervised audio-visual event localization, and cross-modality l...

Guided wave imaging with a sparse array of inexpensive transducers offers a fast, reliable, and cost-efficient means for damage detection and localization in plate-like structures such as aircraft and spacecraft skins. As such, this technology is a natural choice for inclusion in condition-based maintenance and integrated structural health management programs. One of the implementation challeng...

According to its location, the surgical treatment of intracranial meningioma can be of considerable challenge for the neurosurgeon. Image-guided surgery essencially provides intraoperative localization for dynamic navigation and, also, improves the surgical planning. The continuous development of neuroimaging and computated technology promotes continuous improvement of navigation techniques and...

Image-guided surgery represents a new technology with applicability to patients undergoing functional endoscopic sinus surgery for medically refractory rhinosinusitis. It also shows promise in helping to safely expand minimally invasive transnasal endoscopic techniques for nonrhinosinusitis diagnoses of the paranasal sinuses, orbits, and anterior skull base. This report discusses the applicatio...

PURPOSE To determine the frequency with which ultrasonographically (US) guided core biopsy obviated diagnostic surgical biopsy of nonpalpable breast masses, to calculate the cost savings of diagnosis attributable to US-guided core biopsy, and to compare the costs of US-guided versus stereotactically guided core biopsy. MATERIALS AND METHODS US-guided core biopsy was performed in 151 consecuti...

INTRODUCTION Parallel to the advances in diagnostic imaging using positron emission tomography (PET), and availability of new systemic treatment options, the treatment paradigm in oncology has shifted towards more aggressive therapeutic interventions to include cytoreductive techniques and metastasectomies. Intraoperative localization of PET positive recurrent/metastatic lesions can be facilita...
