Investigation of the Use of Hyperspectral Imaging in Foot Surgery Patients

To investigate novel advanced imaging techniques (hyperspectral imaging) that could enable clinicians to determine the degree and effectiveness of blood flow to tissues during surgery. Th...

Intraoperative Hyperspectral Imaging in Gastrointestinal Anastomoses

In this study, gastrointestinal anastomoses are examined with a hyperspectral camera.

Enhancing the Lucentis (Ranibizumab) Management of Choroidal Neovascular Membranes With Hyperspectral Imaging

Clinical trial investigating the role of hyperspectral imaging in the management of patients undergoing standard clinical treatment for naive neovascular choroidal membranes in age-related...

Hyperspectral Imaging to Assess and Predict Diabetic Foot Ulcers

This study is designed to test a prototype imaging instrument that relies on Medical HyperSpectral Imaging (MHSI) technology for the assessment and prediction of diabetic foot ulceration a...

A Study Assessing Circulation Around Surgical Incisions at the Time of Laparotomy Closure

This study is being done to find out if Spectrum Near-Infrared (NIR) imaging with Indocyanine Green (ICG) dye can help measure blood flow around an incision before and after the surgeon cl...

Laser speckle contrast imaging of blood flow in the deep brain using microendoscopy.

Poor blood flow circulation can occur in the subcortical regions of the brain in many brain diseases. However, the limitations of light penetration imaging techniques hinder the detection of blood flo...

Hyperspectral imaging system based on a single-pixel camera design for detecting differences in tissue properties.

Optical spectroscopy can be used to distinguish between healthy and diseased tissue. In this study, the design and testing of a single-pixel hyperspectral imaging (HSI) system that uses autofluorescen...

Snapshot hyperspectral imaging via spectral basis multiplexing in Fourier domain.

Hyperspectral imaging is an important tool having been applied in various fields, but still limited in observation of dynamic scenes. In this paper, we propose a snapshot hyperspectral imaging techniq...

Novel feature-based visualization of the unsteady blood flow in intracranial aneurysms with the help of proper orthogonal decomposition (POD).

The recognition and interpretation of pulsatile subject-specific blood flow is a challenging task. Animations of various quantities - such as blood flow velocity, pressure, or wall shear stress - can ...

Denoising and spatial resolution enhancement of 4D flow MRI using proper orthogonal decomposition and lasso regularization.

4D-Flow MRI has emerged as a powerful tool to non-invasively image blood velocity profiles in the human cardio-vascular system. However, it is plagued by issues such as velocity aliasing, phase offset...

Medical and Biotech [MESH] Definitions

Methods for visualizing REGIONAL BLOOD FLOW, metabolic, electrical, or other physiological activities in the CENTRAL NERVOUS SYSTEM using various imaging modalities.

A pathological condition caused by impaired blood flow in the basal regions of cerebral hemispheres (BASAL GANGLIA), such as INFARCTION; HEMORRHAGE; or ISCHEMIA in vessels of this brain region including the lateral lenticulostriate arteries. Primary clinical manifestations include involuntary movements (DYSKINESIAS) and muscle weakness (HEMIPARESIS).

Visualization of the heart structure and cardiac blood flow for diagnostic evaluation or to guide cardiac procedures via techniques including ENDOSCOPY (cardiac endoscopy, sometimes refered to as cardioscopy), RADIONUCLIDE IMAGING; MAGNETIC RESONANCE IMAGING; TOMOGRAPHY; or ULTRASONOGRAPHY.

A gamma-emitting radionuclide imaging agent used in the evaluation of regional cerebral blood flow and in non-invasive dynamic biodistribution studies and myocardial imaging. It has also been used to label leukocytes in the investigation of inflammatory bowel diseases.

The creation and display of functional images showing where the blood flow reaches by following the distribution of tracers injected into the blood stream.
