Abstract
A diagnostic ultrasound apparatus includes a sound ray signal generator, an extractor and an arithmetic unit. The sound ray signal generator generates a sound ray signal based on a reception signal obtained from an ultrasound probe. The ultrasound probe transmits and receives ultrasound to and from a subject. The extractor extracts imaging signals from the sound ray signal by performing filtering of passing different bands. The arithmetic unit generates a difference signal by using the imaging signals, and performs an arithmetic operation on at least one of the imaging signals by using the difference signal.
Claims17
A diagnostic ultrasound apparatus comprising:
- a sound ray signal generator that generates a sound ray signal based on a reception signal obtained from an ultrasound probe that transmits and receives ultrasound to and from a subject;
- an extractor that extracts imaging signals from the sound ray signal by performing filtering of passing different bands, the imaging signals including a first imaging signal and a second imaging signal, the first imaging signal containing high frequency components and being a wide band and the second imaging signal overlaps the wide band of the first imaging signal and does not contain the high frequency components;
- and
- an arithmetic unit that generates a difference signal by subtracting the second imaging signal from the first imaging signal, and performs an arithmetic operation on the first imaging signal by using the difference signal.
A non-transitory computer readable storage medium storing a program that causes a computer to:
- generate a sound ray signal based on a reception signal obtained from an ultrasound probe that transmits and receives ultrasound to and from a subject;
- extract imaging signals from the sound ray signal by performing filtering of passing different bands, the imaging signals including a first imaging signal and a second imaging signal, the first imaging signal containing high frequency components and being a wide band and the second imaging signal overlaps the wide band of the first imaging signal and does not contain the high frequency components;
- and
- generate a difference signal by subtracting the second imaging signal from the first imaging signal, and perform an arithmetic operation on the first imaging signal using the difference signal.
