  • Publication number: 20220225916
    Abstract: The present invention can provide an apparatus and a method for non-contact measuring momentum, the apparatus and the method being capable of quantitatively measuring the dynamic activity and static activity of a subject by using a plurality of IR-UWB radars and, particularly, capable of measuring, in real time, some activities of the human body and general activity of the human body by distinguishing moving activity of the subject from non-moving activity. Therefore, the activity of a subject is non-contact measured so as to minimize user inconvenience, thereby facilitating performance of an ADHD test even for a subject in a young age group, and thus ADHD can be diagnosed early.

  • Patent number: 9072782
    Abstract: Disclosed are a gadolinium complex formed by coordination of gadolinium to the diethylenetriaminepentaacetic acid dianhydride (DTPA) moiety of a pullulan-DTPA conjugate formed by an ester bond between pullulan and DTPA, a preparation method thereof, an MRI contrast composition comprising the complex, and a method of providing information for diagnosis of disease using the complex as an MRI contrast agent. The pullulan-DTPA-Gd complex has a long in vivo half-life, low toxicity, and high MRI signal intensity resulting in clear MRI images, compared to prior gadolinium complexes, indicating that it is advantageously used as an MRI contrast agent. In addition, it is possible to obtain MRI images allowing one to differentiate between diseased liver tissue and normal liver tissue, indicating that it is used as an MRI contrast agent for the liver.
