Abstract:
Disclosed herein are a medical imaging apparatus including a scanner configured to scan an object, an image generator configured to generate a monitoring image to monitor variations in brightness of a region of interest (ROI) of the object, a controller configured to determine a peak of brightness in the monitoring image, and a user interface configured to display the monitoring image and an indicator of the determined peak, and a method of controlling the same. According to the medical imaging apparatus and the method of controlling the same, over-injection of a contrast agent into the object may be prevented while a medical image is acquired, and an image may be obtained when the contrast agent is in an optimum state in consideration of various environmental factors. Accordingly, lesions and diseases may be more accurately determined and interpreted by using the medical image.
Abstract:
A radiographic imaging apparatus includes a radiation irradiator configured to irradiate radiation to an object; a radiation detector configured to detect an intensity of the radiation passing through the object; and a loader configured to load the object, and at least one of a movement speed of the loader and a range of radiation irradiation of the radiation irradiator is changed according to a change in the intensity of the radiation, when the change in the intensity of the radiation is greater than or equal to a threshold value.
Abstract:
Disclosed is an image processing apparatus and a method of controlling the same. A color contact image sensor (CIS) module employing a single channel line sensor can be used to produce substantially the same performance as a color CIS module employing a three-channel line sensor and having color filters to, for example, reduce manufacturing costs. Moreover, a blurring phenomenon that can occur in a scanned image can be reduced and the quality of the scanned image can be improved.
Abstract:
Disclosed is a tomography apparatus including a controller for estimating a Point Spread Function (PSF) corresponding to a location of an object; and an image processor for de-blurring projection data of the object based on the PSF corresponding to the location of the object.
Abstract:
A radiographic imaging apparatus includes: a radiographic image obtainer configured to acquire a first radiographic image of an object; and a processor configured to obtain attenuation information of the object based on the first radiographic image, determine candidate tube voltages and tube currents based on a quality of a second radiographic image to be obtained, and determine expected exposure doses corresponding to the determined candidate tube voltages and tube currents.
