Publication number: 20230342928Abstract: An ischemic stroke mimic is detected, or otherwise predicted, based on medical images acquired from a subject. Medical image data, which include medical images acquired from a head of the subject, are accessed with a computer system. A machine learning model (e.g., one or more deep convolutional neural networks) is trained on training data to estimate a probability of an acute intracranial abnormality being depicted in a medical image. Intracranial abnormality prediction data are generated by inputting the medical image data to the machine learning model. The intracranial abnormality prediction data include an intracranial abnormality probability score for each of the medical images in the medical image data. An ischemic stroke mimic classification for the medical image data is generated based on the intracranial abnormality prediction data, and may be displayed to a user with the computer system.Type: ApplicationFiled: April 24, 2023Publication date: October 26, 2023Inventors: Synho Do, Byung Chul Yoon, Ramon Gilberto Gonzalez, Michael H.

Patent number: 11615879Abstract: Supervised and unsupervised learning schemes may be used to automatically label medical images for use in deep learning applications. Large labeled datasets may be generated from a small initial training set using an iterative snowball sampling scheme. A machine learning powered automatic organ classifier for imaging datasets, such as CT datasets, with a deep convolutional neural network (CNN) followed by an organ dose calculation is also provided. This technique can be used for patient-specific organ dose estimation since the locations and sizes of organs for each patient can be calculated independently.Type: GrantFiled: September 10, 2018Date of Patent: March 28, 2023Assignee: The General Hospital CorporationInventors: Synho Do, Jung Hwan Cho

Publication number: 20210065414Abstract: Described her are systems and methods for reconstructing images from x-ray attenuation data (e.g., sinogram data) in which metal artifacts are reduced. The algorithms described in the present disclosure take advantage of accurate forward system modeling and one or more iterative reconstruction techniques (IRTs) (e.g., those using compressed sensing) to reconstruct images from incomplete data sets. Rather than replace measurements that are identified as corrupted with inaccurate ones, the systems and methods described in the present disclosure exclude those corrupted measurements in the fidelity term of the energy functional. As a result, the corrupted measurements are not included in the image formation process. In doing so, the reconstruction problem is changed from being about inaccurate data correction to sparse data image reconstruction.Type: ApplicationFiled: September 7, 2018Publication date: March 4, 2021Inventor: Synho Do

Publication number: 20200265578Abstract: Systems and methods for translating medical imaging data for processing using a general processing graphic processing unit (GPGPU) architecture are provided. Medical imaging data acquired from a patient and having data characteristics incompatible with processing on the GPGPU architecture, including at least one of bit-resolution, memory capacity requirements for processing, or bandwidth requirements for processing is translated for processing by the GPGPU architecture.

Translated medical image data is crated using at least one of the window level settings or at least two channel image datasets and then processed using the GPGPU architecture to generate medical images of the patient.Type: ApplicationFiled: September 7, 2018Publication date: August 20, 2020Inventor: Synho DO
