Publication number: 20230280154Abstract: The present disclosure provides an OCT imaging system to reduce or eliminate frequency-domain aliasing artifacts. The frequency is shifted using a carrier frequency to define a sampling range substantially centered on the carrier frequency. An image of the sample is generated from a displayed imaging range that consists of a subset of the frequencies within the sampling range. Furthermore, the system may be configured to determine the carrier frequency such that a Nyquist frequency corresponding to the shifted frequency is extended beyond either an upper or a lower bound of an OCT quality envelope corresponding to the first portion of light. Additionally, the carrier frequency may be determined such that a lower bound of the OCT quality envelope is greater or less than a zero-frequency DC limit.Type: ApplicationFiled: May 15, 2023Publication date: September 7, 2023Applicant: NINEPOINT MEDICAL, INC.Inventors: Eman Namati, Muhammad Al-Qaisi, Matthew A.

Publication number: 20230270347Abstract: A mechanism is provided in a data processing system for automatic determination of b-value difference from diffusion-weighted (DW) images. The mechanism receives a series of images wherein a first image has a first b-value and a second image has an unknown b-value. The mechanism applies a generative adversarial network (GAN) model to estimate a difference between b-values in the series of images. The mechanism determines a b-value for the second image based on the first b-value and the estimated difference between b-values.Type: ApplicationFiled: February 25, 2022Publication date: August 31, 2023Inventors: Amin Katouzian, Marwan Sati, Arkadiusz Sitek, Benedikt Graf, Aly Mohamed, Kourosh Jafari-Khouzani, Frederic Commandeur, Omid Bonakdar Sakhi

Patent number: 11263481Abstract: Mechanisms are provided for determining a measure of radiodensity of anatomical structures of interest and classifying medical imaging study data structures (studies) with regard to contrast phase. In some embodiments, this classification may be used to select/exclude slices for processing by other downstream computing systems. A subset of slices are selected from the study and, for each slice in the subset, a corresponding body part regression (BPR) score is determined. A linear regression on the BPR scores is performed and a representative slice is selected based on results of the linear regression. The representative slice is segmented and a statistical measure of a radiodensity metric for each segment in the representative slice is determined.Type: GrantFiled: January 28, 2021Date of Patent: March 1, 2022Assignee: International Business Machines CorporationInventors: Yusuke Takeuchi, Benedikt Graf, Yiting Xie
