Patents by Inventor Chul-Seung Kay

Chul-Seung Kay has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12097385
    Abstract: A lung phantom unit for radiotherapy according to an embodiment of the present disclosure may arrange, at a location not affected by a magnetic field, a phantom driving cylinder and a driving device which may move a lung mimic and a tumor mimic in a lung simulation block. The lung phantom unit may be used for general purpose even as a phantom for MRI-based and CT image-based radiotherapy. Since lung and tumor motions are implemented by air injection, it may be possible to precisely measure the motion and volume change of a lung according to subtle changes in air pressure so that customized radiotherapy suitable for a patient having various breathing patterns is possible.
    Type: Grant
    Filed: October 8, 2020
    Date of Patent: September 24, 2024

  • Patent number: 10602956
    Abstract: The present invention relates to a radiation amount estimating method, and more particularly, to a radiation amount estimating method of an MRI based composite image using a lookup table. To this end, the object of the present invention is to provide a radiation dose estimating method of an MRI based composite image using a lookup table including: generating a lookup table representing a linear attenuation coefficient of a region of interest from a CT image (S100); photographing at least two of a T1 image, a T2 image, and a PETRA image of a patient from MRI equipment (S120); generating a composite image by superimposing the photographed images (S140); representing a border line of the region of interest in the composite image to distinguish the region of interest (S160); designating the linear attenuation coefficient of the lookup table in the distinguished region of interest (S180); and estimating a radiation dose based on the composite image to which the linear attenuation coefficient is designated (S200).
