Tissue Characterization With Hyperspectral Maging (HSI)

2020-01-21 11:31:41 | BioPortfolio

Summary

Hyperspectral Imaging (HSI) is a contact free method to analyse the from the tissue reflected light in the range of 500-1000nm. Aim of the study is to identify special reflex patterns to identify special tissue

Description

This HSI-camera provides hyperspectral images with a high spectral resolution (5 nm) in the visible and near infrared range (500-1000 nm). A RGB image and 4 false color images that represent physiologic parameters are intraoperatively provided by an analysis software. But after the procedure all spectral datasets could be investigated. To analyse and differentiate the different tissues, a catalog database is needed of all tissues including Tumors.

Medical and Biotech [MESH] Definitions

The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.

The chilling of a tissue or organ during decreased BLOOD perfusion or in the absence of blood supply. Cold ischemia time during ORGAN TRANSPLANTATION begins when the organ is cooled with a cold perfusion solution after ORGAN PROCUREMENT surgery, and ends after the tissue reaches physiological temperature during implantation procedures. WARM ISCHEMIA TIME starts then and ends with completion of SURGICAL ANASTOMOSIS.

A technique for maintaining or growing TISSUE in vitro, usually by DIFFUSION, perifusion, or PERFUSION. The tissue is cultured directly after removal from the host without being dispersed for cell culture.

Non-invasive imaging methods based on the mechanical response of an object to a vibrational or impulsive force. It is used for determining the viscoelastic properties of tissue, and thereby differentiating soft from hard inclusions in tissue such as microcalcifications, and some cancer lesions. Most techniques use ultrasound to create the images - eliciting the response with an ultrasonic radiation force and/or recording displacements of the tissue by Doppler ultrasonography.

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