Publication number: 20240389856Abstract: Deoxyhemoglobin contrast has been used to locate arteries based on the earlier blood oxygen-level dependent (BOLD) signal arrival time, higher BOLD signal strength, and shorter mean transit time. However, additional strategies of identifying arteries with oxygen modulation are required to improve the sensitivity and specificity of results. The present disclosure provides a method of distinguishing extravascular voxels from intravascular voxels based on the magnetic signal obtained from two hypoxic boluses having two different baselines. Intravascular voxels are responsive to changes in the baseline due to their high blood volume, while extravascular voxels are not affected by changes to the baseline. Amongst intravascular voxels, arteries can be distinguished from veins because the extraction fraction of the arterial blood is reduced during hypoxia, and therefore veins are less sensitive to changes in the baseline.Type: ApplicationFiled: September 29, 2022Publication date: November 28, 2024Inventors: Jacob B.

Publication number: 20240389882Abstract: A non-transitory machine-readable media storing instructions that, when run by one or more processors, cause the one or more processors to store a deformable model of anatomic passageways of a patient anatomy. The deformable model comprises a plurality of model passageway links connected at connection points, and each of the model passageway links includes a centerline. At each respective connection point, the corresponding passageway links include an orientation. The instructions further cause the one or more processors to modify the deformable model by modifying relative orientations of one or more model passageway links of the plurality of model passageway links. The modifying is based on one or more modeling parameters that affect a shape of the plurality of model passageway links.Type: ApplicationFiled: August 2, 2024Publication date: November 28, 2024Inventors: Vincent Duindam, Prashant Chopra, Tao Zhao

Publication number: 20240389884Abstract: A respiratory event determination system can have a controller that determines the presence of a respiratory event. The respiratory event can be a mouth puff event. The controller determines the presence as a function of a sub-window of an expiratory window of the breath. The expiratory window extends between a first time t1 and a second time t2. The sub-window is limited to a portion of the expiratory window. The sub-window can extend between a third time t3 and a fourth time ta. The fourth time ta can be before the second time t2.Type: ApplicationFiled: July 31, 2024Publication date: November 28, 2024Inventor: Amol Man Malla

Publication number: 20240389887Abstract: Systems and methods for monitoring limb function. An example method includes obtaining sensor data from individual devices worn on individual limbs of a user, the devices generating sensor data indicative of, at least, acceleration information associated with the limbs. The obtained sensor data is adjusted for input into a machine learning model, with the machine learning model being a deep learning model. A forward pass is computed through the machine learning model, with the machine learning model being trained to output information indicative of goal-directed movements (GDMs) performed by the user. Information indicative of GDMs is obtained via the machine learning model, with the information reflects particular labels identifying particular GDMs.Type: ApplicationFiled: May 23, 2024Publication date: November 28, 2024Inventors: Adonay Nunes Sastre, Ilkay Yildiz Potter, Ram Kinker Mishra, Ashkan Vaziri
