(b) MSOT images of the ICG accumulating in the sentinel lymph node (in color), overlaid on a background image of tissue illuminated at a single wavelength. Each image came from a different patient. (c) MSOT imaging of melanin (in color) overlaid on a background image of tissue. The first image shows a patient without melanoma metastasis.
MSOT has also been used to visualize metabolism within brown fat, [17] suggesting it may be effective for analyzing muscle energetics and lipid metabolism in a much simpler and more accessible way than with other techniques such as magnetic resonance imaging.

Photoacoustic imaging or optoacoustic imaging is a biomedical imaging modality based on the photoacoustic effect.Non-ionizing laser pulses are delivered into biological tissues and part of the energy will be absorbed and converted into heat, leading to transient thermoelastic expansion and thus wideband (i.e. MHz) ultrasonic emission.
Near-IR absorption spectrum of dichloromethane showing complicated overlapping overtones of mid IR absorption features.. Near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 nm to 2500 nm). [1]
Medical optical imaging is the use of light as an investigational imaging technique for medical applications, pioneered by American Physical Chemist Britton Chance. Examples include optical microscopy , spectroscopy , endoscopy , scanning laser ophthalmoscopy , laser Doppler imaging , optical coherence tomography , and transdermal optical imaging .
Segmentation is the process of partitioning an image into different meaningful segments. In medical imaging, these segments often correspond to different tissue classes, organs, pathologies, or other biologically relevant structures. [2] Medical image segmentation is made difficult by low contrast, noise, and other imaging ambiguities.
Conservators in London, England used infrared and X-ray imaging to reveal a never-before-seen portrait of a woman beneath a popular painting by renowned artist Pablo Picasso. The Courtauld ...
Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices.
