Abstract: 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.

Abstract: Disclosed is a depth map calculation method and apparatus. The depth map calculation method includes calculating a global sparse depth map corresponding to a current frame using frames including the current frame, calculating a local dense depth map corresponding to the current frame using the current frame, extracting a non-static object region from the current frame by masking a static object region, removing the non-static object region from the global sparse depth map, and generating a global dense depth map corresponding to the current frame by merging the non-static object region-removed global sparse depth map and the local dense depth map.
