1. Field
Embodiments of the present disclosure relate to a medical imaging apparatus including a noise reducing apparatus.
2. Description of the Related Art
A medical imaging apparatus is an apparatus configured to obtain an internal image of a human body by allowing a constant energy to pass through a human body and using characteristics of incidence, reflection or transmission depending on the density and property of internal parts of the human body. For decades, the medical imaging was achieved only by applications of radioactive rays, but in the recent years, various medical imaging devices have been developed using ultrasonic waves, magnetic field, and laser.
A ultrasound imaging apparatus, an example of the medical imaging apparatus, obtains an image of the inside of an object, such as a soft tissue tomogram or a blood stream tomogram in a non-invasive manner by emitting ultrasound signals toward a target region from the surface of the object and using reflected ultrasound signals (ultrasound eco signals).
The ultrasound imaging apparatus has a compact structure, a low cost, a real-time operation and no risk of exposure to radioactive rays, as compared to other diagnostic imaging apparatuses, such as X-ray diagnosis apparatuses, X-ray Computerized Tomography Scanner (CT scanner), magnetic resonance imaging (MRI) apparatuses, and nuclear medicine diagnosis apparatuses.
