Latest Patents

Hiroshi Kawaguchi holds a patent for a method that generates images for PET attenuation correction from MR images. This patent, which is crucial for improving the quality of PET scans, involves segmenting the MR image captured by MRI into regions based on pixel values. In regions where the radiation attenuation coefficient is uniform, a correction value is determined using an existing table. For areas with multiple tissues that have different attenuation coefficients, a standard image is referenced to establish the correction value. This method allows for the distinction of tissues with similar pixel values but varying radiation attenuation coefficients, accommodating individual differences and affected areas such as tumors or organic defects.
