WebIodine-131 is a well-known radioactive isotope with a half-life of 8.02 days, which has been extensively used in various medical applications. One of its key applications is as a radiolabel for human serum albumin (HSA), the most abundant protein in human plasma. Iodine-131 human serum albumin (I-131 HSA) has been utilised for a range of ... Multi-spectral optoacoustic tomography (MSOT), also known as functional photoacoustic tomography (fPAT), is an imaging technology that generates high-resolution optical images in scattering media, including biological tissues. MSOT illuminates tissue with light of transient energy, typically light … See more MSOT has been described as a 6-dimensional (6-parametric) method, in which the three geometrical dimensions (x, y, z) are complemented by time, illumination wavelengths and band of ultrasound … See more MSOT has the potential to provide multi-parametric information involving the three spatial dimensions (x, y, z), time, optical wavelength spectrum and ultrasound frequency range. It has therefore been described as a six-dimensional modality. This dimensionality … See more Optoacoustic imaging in general, and MSOT in particular, have been applied to various analyses of animal models, including imaging of organs, pathology, functional … See more Multi-spectral. MSOT collects images at multiple wavelengths and resolves the spectral signatures in each voxel imaged, making it a multi-spectral method. Typically, MSOT is … See more MSOT detects photoechoes, i.e. ultrasound waves generated by thermo-elastic expansion of a sample (e.g. tissue) after absorption of transient electromagnetic energy. Typically, the sample is illuminated with light pulses in the nanosecond range, although intensity … See more Modes of operation MSOT can operate in three imaging modes: 1.
