Latest Patents

One of Issei Sato's latest patents is titled "Methods and systems for cytometry." This patent introduces ghost cytometry (GC), a technique that allows for the imaging of objects without the need for a spatially resolving detector. This innovative approach enables image-free ultrafast fluorescence imaging cytometry, utilizing a single pixel detector. The technology captures spatial information from the motion of cells in relation to a patterned optical structure, which is then converted into signals that are processed sequentially. By combining the temporal waveform with the intensity distribution of random or pseudo-random patterns, Sato's method facilitates the computational reconstruction of cell morphology. Additionally, machine learning techniques can be applied directly to the compressed waveforms, allowing for efficient morphology-based cytometry without the need for image reconstruction. This image-free GC method achieves accurate and high-throughput cell classification and selective sorting based on cell morphology, overcoming challenges faced by conventional flow cytometers.

Another notable patent is an "Analysis device," which includes an analysis unit designed to receive various forms of light, such as scattered light, transmitted light, and fluorescence. This device analyzes observed objects based on signals extracted from the time axis of electrical signals generated by a light-receiving unit. The innovative design enhances the analysis capabilities of biological samples.
