Publication number: 20240074738Abstract: An ultrasound imaging system includes an a processor circuit that stores, in a memory in communication with the processor circuit, a target parameter representative of a target anatomical scan window. The processor circuit receives a first ultrasound image acquired by a first ultrasound probe with a first anatomical scan window during a first acquisition period. The processor circuit determines a first parameter representative of the first anatomical scan window. The processor circuit retrieves the target parameter from the memory. The processor circuit compares the target parameter and the first parameter. The processor circuit outputs a visual representation of the comparison to a display in communication with the processor circuit.Type: ApplicationFiled: December 13, 2021Publication date: March 7, 2024Inventors: Jochen Kruecker, Gary Cheng-How Ng, Raghavendra Srinivasa Naidu, Man M Nguyen, Hua Xie

Publication number: 20240055936Abstract: A vibration actuator (10) for mechanically generating a shear wave comprises a plurality of n rotational vibrators (141, 142, 143), an accelerometer (16), and a controller (18). The plurality of n rotational vibrators enables generation of a vibration vector with desired directional behavior selected from a plurality of vibration vectors (34, 36, 38) of different directional behaviors. Each rotational vibrator comprises an independently controllable motor (20) having a drive shaft (22) and an eccentric disk (24). The accelerometer is arranged to detect a vibration vector generated by at least two of the plurality of n rotational vibrators.Type: ApplicationFiled: December 14, 2021Publication date: February 15, 2024Inventors: Man M Nguyen, Ramon Quido Erkamp

Publication number: 20240029896Abstract: The present disclosure describes systems configured to recognize indicators of a medical condition within a diagnostic image and predict the progression of the medical condition based on the recognized indicators. The systems can include neural networks trained to extract disease features from diagnostic images and neural networks configured to model the progression of such features at future time points selectable by a user. Modeling the progression may involve factoring in various treatment options and patient-specific information. The predicted outcomes can be displayed on a user interface customized to specific representations of the predicted outcomes generated by one or more of the underlying neural networks. Representations of the predicted outcomes include synthesized future images, probabilities of clinical outcomes, and/or descriptors of disease features that may be likely to develop over time.Type: ApplicationFiled: December 7, 2021Publication date: January 25, 2024Inventors: Man M Nguyen, Jochen Kruecker, Raghavendra Srinivasa Naidu, Haibo Wang

Publication number: 20230181162Abstract: An ultrasonic diagnostic imaging system performs elastography using mechanically generated vibrations from a vibration assembly attached to an ultrasound probe. An attachment member attaches the vibration assembly to the probe. A vibration motor is mounted in a motor mount and applies vibration energy to the body in which shear waves are to be measured, at a location adjacent to the probe. The vibration motor mount is coupled to the attachment member by a vibration isolation element such as a spring, rubber band, or elastic compound which isolates the probe from deleterious vibration energy from the vibration motor.Type: ApplicationFiled: May 7, 2021Publication date: June 15, 2023Inventors: Mostafa Abdelaziz Ali Atalla, Ramon Quido Erkamp, Man M Nguyen

Publication number: 20220401078Abstract: Systems and methods for calculating hepato-renal index (HRI) values from radiofrequency (RF) data are disclosed herein. The RF data may include fundamental frequency components, harmonic frequency components, or a combination thereof. Signal intensities within regions of interest may be calculated from the RF data. The signal intensities may be averaged to arrive at an average signal intensity value for each region of interest. In some examples, some of the highest and/or lowest signal intensity values may be removed prior to averaging. The ratio of the average signal intensities from the different regions of interest may be then be taken to arrive at the HRI values.Type: ApplicationFiled: November 22, 2020Publication date: December 22, 2022Inventors: Sheng-Wen Huang, Hua Xie, Man M Nguyen, Vijay Thakur Shamdasani, William Tao Shi

Publication number: 20220087653Abstract: An ultrasound system produces maps of acoustic attenuation coefficients from pulse echo signals. Maps are produced using different attenuation coefficient or slope estimation methods, and a plurality of maps from different estimation methods are compounded to produce a final attenuation coefficient map. Confidence maps may also be produced for one or more attenuation coefficient maps, and the confidence map displayed or its measures used to determine weighting for the compounding process.Type: ApplicationFiled: January 20, 2020Publication date: March 24, 2022Inventors: SHENG-WEN HUANG, HUA XIE, MAN M. NGUYEN, CAROLINA AMADOR CARRASCAL, JEAN-LUC FRANCOIS-MARIE ROBERT, VIJAY THAKUR SHAMDASANI

Patent number: 11185342Abstract: According to aspects of the present disclosure, a retrieval device may include a sheath, a first drive member in the sheath, and a second drive member in the sheath. The second drive member may be movable relative to the first drive member. An end effector may be retractable into and extendable out of the sheath. The end effector may include a first proximal end portion coupled to the first drive member, a second proximal end portion coupled to the second drive member, and a plurality of legs extending distally from the first and second proximal end portions to a distal tip of the end effector. All of the legs that extend to the distal tip may be fixed together at the distal tip.Type: GrantFiled: October 28, 2019Date of Patent: November 30, 2021Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Man M.

Publication number: 20210137416Abstract: The present disclosure describes imaging systems configured to generate adaptive scanning protocols based on anatomical features and conditions identified during a prenatal scan of an object. Systems may include an ultrasound transducer configured to acquire echo signals responsive to ultrasound pulses transmitted toward a target region. Processors coupled with the transducer can generate an image frame from the echoes and provide the image frame to a first neural network. The first neural network may be configured to identify an anatomical feature in the image frame. An indication of the anatomical feature may be provided a second neural network. The second neural network may then determine an anatomical measurement to be obtained based, in part, on the feature identified. The processors may be further configured to cause an indicator of the anatomical measurement to be obtained to be displayed on a user interface.Type: ApplicationFiled: April 11, 2019Publication date: May 13, 2021Inventors: EARL M. CANFIELD, MAN M. NGUYEN, HUA XIE
