Measuring the oxygen saturation is of great value in a wide range of medical fields. For instance, tumor progression and malignancy is strongly dependent on tumor hypoxia. Monitoring of cerebral oxygen saturation can be used in the diagnosis of cerebral desaturations in stroke patients. In cardiovascular disease and diabetes the measurement of abnormalities of the microcirculation can monitor the

This project focus on evaluating and optimizing photoacoustic (PA) imaging as a method to non invasively diagnose giant cell arthritis. Giant cell arteritis (GCA) also known as temporal arteritis is a sight- and life-threatening, granulomatous large-vessel condition. Typical symptoms are headache, fever, fatigue, night sweats and weight loss. GCA may not only cause permanent loss of vision, but al

LSCI is a non-invasive technique to measure blood perfusion. The method that visualizes tissue blood perfusion in real time. The system uses an invisible 785 nm laser beam that is spread over the surface of the skin by a diffuser, creating a speckle pattern formed by random interference in the backscattered light from the area illuminated by the laser. Blood perfusion is calculated by analyzing th

Diffuse reflectance spectroscopy (DRS) utilizes white light with a known spectrum, which is guided to the surface of the skin via an optical fiber. As light penetrates into the tissue, photons either scatter or become absorbed where only a fraction of the injected photons manage to escape back from the skin surface. This light is captured by a second fiber and measured with a spectrometer. Dependi

Hyperspectral imaging has traditionally been employed for environmental monitoring where large swaths of land have been surveyed miles above from air planes. With the capability of resolving minute spectral changes in space, different types of vegetation and soils could be identified over large areas, which has been useful to recognize the prevalence of various crop diseases. Today, the method is

When employing optical characterization of human tissue it is important to obtain proper characteristics of all its constituents that coexist in a complex fashion. This requires that each constituent is isolated and measured independently to determine how it reacts to different wavelengths of light (primarily absorption). Besides the hyperspectral camera, we have a multispectral microscope which e

Implement in-house state-of-the-art motion-tracking methods into our novel PAI application and evaluate its performance. During a scan, motion artifacts arise as a result of movements of the operator or the patient, and from breathing and tissue movements. To reduce movements of the operator and patient we have developed a transducer holder and stabilized the patient using a vacuum pillow (Sheikh

A key feature of photoacoustic imaging is its ability to illuminate tissue at multiple wavelengths, and thus record images with a spectral dimension. Spectral imaging allows sensing of intrinsic chromophores that can reveal physiological, cellular and subcellular functions. However, the identification of spectral signatures within images obtained at multiple wavelengths requires spectral unmixing

Heart failure is a leading cause of death and hospitalization in Sweden today, with a prevalence of between 200 000 to 300 000 subjects. Heart failure is characterized by increased intracardiac pressures and declining output of blood, representing the end-result of many different etiologies that adversely affect cardiac structure and function. Increasing availability of etiology-specific therapies

Evaluating tissue heating from near-infrared lasers. With the rise of biophotonics in medical applications such as photodynamic therapy (PDT), laser induced fluorescence (LIF) and gas in scattering media absorption spectroscopy (GASMAS) the tissue heating properties of lasers in the tissue optical window is an increasingly interesting topic. These wavelengths in the range between 700 and 1100 nm
