Current methods for reconstructing three-dimensional B-mode ultrasound images suffer from reconstruction errors that reduce accuracy, particularly in displaying the brightness and definition of detected objects.
Innovation Solution
A method involving a one-time modulus value calculation on three-dimensional radio-frequency signals to obtain envelope information, using a hypercomplex signal with 8 components represented by modulus values and angles, which improves the accuracy of three-dimensional ultrasound images by directly acquiring the three-dimensional amplitude of the radio-frequency signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If one-dimensional envelope signals are spliced to reconstruct three-dimensional B-mode ultrasound images, then the reconstruction process can be completed, but reconstruction errors occur that reduce image accuracy
Solution Approach 1:
The patent transitions from one-dimensional envelope signal processing to three-dimensional hypercomplex signal processing. By performing modulus value calculation directly on the three-dimensional radio-frequency signal to obtain three-dimensional envelope information, the method eliminates the need to splice one-dimensional signals, thereby avoiding reconstruction errors and improving image accuracy
Solution Approach 2:
The patent combines multiple one-dimensional envelope signals into a unified three-dimensional envelope image through hypercomplex signal processing. The eight components of the hypercomplex signal are integrated to form a comprehensive three-dimensional representation, merging separate processing paths into a single accurate reconstruction
2Illumination intensity
If conventional envelope detection methods are used, then the processing steps are simple, but the brightness and definition of detected objects are insufficient
Solution Approach 1:
The patent changes the parameter of envelope detection from conventional one-dimensional modulus calculation to three-dimensional hypercomplex modulus value calculation. This parameter change enables simultaneous improvement of brightness (through comprehensive three-dimensional amplitude information) and definition (through accurate envelope extraction in three-dimensional space)

AI summary
Disclosed are an ultrasound image display method and apparatus, and a storage medium and an electronic apparatus. The method comprises: acquiring an input signal obtained by a detection device detecting an object to be detected, wherein the input signal is a three-dimensional radio frequency signal; performing one-time modulus value calculation on the three-dimensional radio frequency signal to obtain envelope information in a three-dimensional ultrasound image, wherein the one-time modulus value calculation is at least used to directly acquire a three-dimensional amplitude of the three-dimensional radio frequency signal; and displaying the envelope information in the three-dimensional ultrasound image, wherein the envelope information is used to indicate the object to be detected. The present application solves the technical problem in the related art that the accuracy of a reconstructed three-dimensional B-mode ultrasound image is reduced beacuse the reconstructed three-dimensional B-mode ultrasound image has reconstruction errors.
