2D Ultrasound Transducer Array for 3D Imaging and Ease of Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ultrasound imaging systems are complex and difficult for less trained clinicians to use effectively, as they require skilled maneuvering of the probe to capture useful images, which can be challenging due to the invisible nature of the ultrasound beam and the need for indirect feedback.
Innovation Solution
The system employs a 2D array of ultrasound transducers that uses beam steering to generate multiple ultrasound signals at different angles, allowing for the creation of a 3D model of the anatomical target by processing a series of images taken along an elevational direction, which can be displayed from various perspectives without repositioning the probe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional ultrasound probe with manual maneuvering is used, then image collection capability is available, but the system becomes difficult to use for less trained clinicians
Solution Approach 1:
The system performs automated probe positioning and image acquisition without requiring manual maneuvering by the operator. The ultrasound probe automatically adjusts its position and orientation to capture optimal images, eliminating the need for trained sonographers to manually manipulate the probe while maintaining comprehensive image collection capabilities
Solution Approach 2:
The patent replaces the mechanical manual maneuvering system with an automated computational system. Instead of relying on human operators to physically position the probe, the system uses image processing algorithms and automated control mechanisms to achieve proper probe positioning and image acquisition, substituting mechanical human操作 with automated electronic control
2Adaptability or versatility
If beam steering is used to capture images from multiple angles, then diagnostic capability is improved, but the system complexity increases
Solution Approach 1:
The ultrasound probe incorporates a two-dimensional array of transducer elements that serves multiple functions: it can transmit and receive ultrasound waves from multiple angles simultaneously, perform beam steering electronically, and capture comprehensive anatomical data. This multi-functional design enables enhanced diagnostic capability without requiring separate specialized devices for each imaging angle
Solution Approach 2:
The patent transitions from traditional one-dimensional linear array transducers to a two-dimensional array configuration. This dimensional enhancement allows the system to steer beams in both azimuth and elevation directions, capturing images from multiple angles and creating three-dimensional reconstructions, thereby improving diagnostic capability through added spatial dimensionality

AI summary
The systems and methods for generating a three-dimensional (3D) model of an imaging target of an ultrasound scan. In one aspect, an ultrasound device having a two-dimensional (2D) flat array of micromachined ultrasound transducers can utilize beam steering to take a series of ultrasound images at a range of angles along an axis. The images may be collected, analyzed and processed to generate a 3D model of the subject matter from the series of images. The system can then display, to a user, a view of the imaging target from a point of view other than the point of view at which the target was originally imaged.
