Abstract
A processing system according to an aspect of the present disclosure includes a transmittance filter obtaining unit and a correcting unit. The transmittance filter obtaining unit obtains a transmittance filter representing complex transmittances corresponding to a plurality of frequencies in the case where an acoustic wave passes through a first medium. The correcting unit corrects an electric signal by using the transmittance filter and obtains a corrected electric signal.
Claims20
A processing system that processes an electric signal obtained as a result of a receiving unit receiving an acoustic wave that has been produced in a subject and has passed through a first medium, the processing system comprising:
- a transmittance filter obtaining unit configured to obtain a transmittance filter representing complex transmittances corresponding to a plurality of frequencies in a case where the acoustic wave passes through the first medium;
- and
- a correcting unit configured to correct the electric signal by using the transmittance filter and to obtain a corrected electric signal.
A signal processing method for processing an electric signal derived from an acoustic wave that has been produced in a subject and has passed through a first medium, the signal processing method comprising:
- obtaining a transmittance filter representing complex transmittances corresponding to a plurality of frequencies in a case where the acoustic wave passes through the first medium;
- and
- correcting the electric signal by using the transmittance filter and obtaining a corrected electric signal.
A non-transitory storage medium storing a program that causes a computer to perform a signal processing method for processing an electric signal derived from an acoustic wave that has been produced in a subject and has passed through a first medium, the signal processing method comprising:
- obtaining a transmittance filter representing complex transmittances corresponding to a plurality of frequencies in a case where the acoustic wave passes through the first medium;
- and
- correcting the electric signal by using the transmittance filter and obtaining a corrected electric signal.
