SYSTEMS AND METHODS OF SPARSE ORTHOGONAL DIVERGING WAVE ULTRASOUND IMAGING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240329241 titled 'SYSTEMS AND METHODS OF SPARSE ORTHOGONAL DIVERGING WAVE ULTRASOUND IMAGING
The abstract describes a patent application for a method of transmitting encoded signals to an ultrasound array to sequentially transmit diverging ultrasound waves. Each wave is generated by a set of encoded signals, encoded by a row of an invertible orthogonal matrix. A subset of rows is used to encode the signals, which are then decoded using a transposed matrix based on the orthogonal matrix. Synthetic aperture beamforming is performed on the decoded signals to create an ultrasound image.
- Encoded transmit signals are provided to an ultrasound array for sequential transmission of diverging ultrasound waves.
- Each wave is generated by a set of encoded signals, encoded by a row of an invertible orthogonal matrix.
- Only a selected subset of rows is used to encode the signals.
- Decoding of received signals is done using a transposed matrix based on the orthogonal matrix.
- Synthetic aperture beamforming is performed on the decoded signals to generate an ultrasound image.

Original Abstract Submitted
encoded transmit signals are provided to an ultrasound array such diverging ultrasound waves are sequentially transmitted. each diverging ultrasound wave is generated by a respective set of encoded transmit signals, where each set of encoded transmit signals is encoded by a respective row of an n�n invertible orthogonal matrix. only a selected subset of m rows, with n<m, is employed to encode the transmit signals. sets of receive signals detected in response to the transmitted diverging ultrasound waves are decoded via a transposed matrix generated based on the invertible orthogonal matrix, with each set of decoded receive signals being associated with insonification via a subset of the ultrasound array elements in the fixed aperture. synthetic aperture beamforming is performed on the decoded receive signals to generate an ultrasound image.
