Robotics and Virtual Reality for Optical Coherence Tomography-Guided Ophthalmic Surgery and Diagnostics
… employs both microsurgical techniques and live intraoperative imaging, especially optical coherence tomography (OCT). Consequently, ophthalmic surgeons routinely face challenges in visualization and manipulation of small ocular tissues or in interpreting intraoperative imaging to guide their …

Development of a three-dimensional camera based on subsampled optical coherence tomography (OCT)
… (OCT) allows label-free, three-dimensional imaging of tissue structure. Current implementations of OCT can either image over long depth ranges at slow imaging speeds, or over limited depth ranges at high speeds. Here, we describe a new OCT paradigm that supports simultaneous high speed and …

Biomechanically Constrained Ultrasound to Computed Tomography Registration of the Lumbar Spine
… of the spine is changed between preoperative and intraoperative imaging. For datasets where the spine curve between two imaging modalities was artificially perturbed, the proposed methodology was able to register initial misalignments of up to 20 mm with a success rate of 95%. For the phantom with …

Multimodality Somatostatin Analog For Fluorescence-Guided Surgery In Cancer
… tumors (NETs). Anatomical and functional imaging technologies are widely used during the pre- and postoperative stages, but intraoperative disease recognition relies on direct visual inspection and the hands of surgeons. The limited number of clinical tools for real-time intraoperative …

Spectrally Resolved Detector Arrays for Multiplexed Biomedical Fluorescence Imaging
… video rate applications, such as endoscopy and intraoperative imaging, has traditionally been limited by the use of filter-based imaging systems. Hyper and multispectral imaging facilitate the detection of both spatial and spectral information in a single data acquisition, however, …

Two-dimensional exploration of two-dimensional carbon : imaging and sensing applications
With the emerging need for advanced sensing and imaging capabilities in personalized healthcare, there has been motivation to develop new classes of nanomaterials; with performance vastly superior to existing technologies. In this work, we explore the one- and two-dimensional forms of carbon …

A Human Factors Analysis and Classification System (HFACS) Approach to Compare Cardiovascular, Orthopedics, Trauma Care, and Neurosurgery
… and coded using HFACS. We analyzed almost 8,943 intraoperative events. Trained analysts used three coding strategies: unanimous, majority, and reconciled consensus to assess interrater reliability.</p> <p><strong>Main Outcomes and Measures:</strong> Primary outcomes included frequency and …

Non-contact quantitative imaging of limbs, bone and tissue, using ultrasound tomographic techniques
… sets collected on two custom built ultrasound imaging systems for limb imaging. The images are quantitative in that the distribution of sound speeds and dimensionally accurate geometry of tissue structures are reconstructed. The first imaging system is based on laser generation and detection of …

Plasmonic Nanoplatforms and Surface-enhanced Raman Spectroscopy for in vivo Sensing: from Plants to Animals
… served as a strong contrast agent for two-photon imaging, photoacoustic imaging, and Raman mapping during in vivo experiments in Tobacco leaves. The AuNR@Ag was further functionalized with iMS technology and was applied for sensing for microRNA targets in leaf tissue. To our knowledge, this is the …

Experience using a small field of view gamma camera for intraoperative sentinel lymph node procedures
… use of blue dye or the use of a radiotracer with intraoperative gamma counting. The most complex procedures involve the use of blue dye, the use of a radiotracer with preoperative gamma imaging and preoperative gamma counting, intraoperative gamma counting, or some combination of these techniques. …

Label-free multi-modal multiphoton imaging for real-time point-of-procedure assessment of needle biopsies
… demand. Label-free multimodal nonlinear optical imaging (NLOI) provides a powerful and non-invasive tool to study the microstructure and biochemical distributions in biological tissue, especially in tumor microenvironments. Continuous efforts have been devoted to the development and optimization …
