An ultrasound imaging apparatus and a method of controlling the same are provided. The ultrasound imaging apparatus includes an ultrasound contrast agent (UCA) sensor configured to determine whether an UCA flows in an object based on an echo signal that is reflected by the object in a mechanical index environment. The ultrasound imaging apparatus further includes a controller configured to obtain at least one among an UCA image and a tissue image of the object in another mechanical index environment lower than the mechanical index environment in response to the UCA sensor determining that the UCA flows in the object.

Ultrasound imaging apparatus and method of controlling the same

A medical image processing apparatus includes a weight applier configured to, when a difference between a first imaginary component of a first frame image and a second imaginary component of a second frame image, the second frame image being adjacent to the first frame image, is less than or equal to a first threshold value, apply a first weight to the second imaginary component to increase the difference; and an image generator configured to generate a movement-amplified image based on the first frame image and the second frame image to which the first weight is applied so that a movement of interest corresponding to the increased difference is amplified.

Image processing apparatus, ultrasonic apparatus including the same and method of controlling the same

Disclosed herein are an ultrasonic imaging apparatus and a control method thereof. The ultrasonic imaging apparatus includes: an ultrasonic collector configured to collect ultrasonic waves from an object; a volume data generator configured to generate volume data based on the ultrasonic waves; and an image processor configured to perform volume rendering on the volume data with reference to a texture image, wherein a translucency property and multi-layer tissue of the object are reflected to each texel of the texture image.

Ultrasonic imaging apparatus and control method thereof

Ultrasonic imaging method includes sequentially emitting by each transducer group of respective regions, into which transducers are divided, focused ultrasonic pulses to a focal point of an object; sequentially acquiring, by each transducer group, ultrasonic echo signals from the focal point based on the emitted ultrasonic pulses; calculating a normal vector of a surface of the object using emission directions of the focused ultrasonic pulses and intensities of the ultrasonic echo signals in correspondence to the focused ultrasonic pulses emitted by three of the transducer groups; calculating an attenuation rate of the ultrasonic echo signals using the normal vector and the emission directions of the focused ultrasonic pulses emitted by the three of the transducer groups, and correcting the ultrasonic echo signals based on the attenuation rate; beamforming the ultrasonic echo signals, an attenuation of which has been corrected, into ultrasonic image signals to be output as an ultrasonic image.

Apparatus for processing ultrasonic image and method thereof

An ultrasonic imaging method includes emitting ultrasonic pulses in different directions and acquiring ultrasonic echo signals from an object, calculating an attenuation rate of the ultrasonic echo signals, correcting the acquired ultrasonic echo signals based on the attenuation rate, and outputting the corrected ultrasonic echo signals as an ultrasonic image.

A method and an apparatus of enhancing a ray tracing speed. The method of enhancing a ray tracing speed may group a secondary ray based on a direction of the secondary ray in a 3D space, and may perform packet tracing based on the grouped secondary ray.
