A method is provided for modifying an image. The method comprises displaying an image, the image comprising a portion of an object; and determining if an edge of the object is in a location within the portion.

Methods and systems are disclosed for relating additional spatial information associated with one volume data set of an anatomical structure with another volume data set of the anatomical structure where the spatial information is not available. A unique spatial characteristic of the volume data set is identified, such as an image moment of inertia, and an arbitrary reference frame is assigned to the volume data set and correlated with the unique spatial characteristic. The additional spatial information is also correlated with the arbitrary reference frame. The additional spatial information is then correlated to a second volume data set of the anatomical structure by registering the first and second volume data sets based on the unique spatial characteristic. The methods and systems allow registration of different volume data sets of the same anatomical structure and transfer of the additional spatial information without establishing a local reference frame based on predefined landmarks.

Registration of anatomical data sets

PROBLEM TO BE SOLVED: To enable appropriate management and search of information.SOLUTION: An information processing apparatus according to one embodiment of the present disclosure includes a collection unit, a storage unit, and a search unit. The collection unit collects a plurality of first metadata relating to information for which a common specification to a plurality of information sources transmitting the information is not stipulated, from the information sources. The storage unit stores a first attribute indicating an item of an element included in the first metadata and a first attribute value that is a value corresponding to the first attribute while making the first attribute and the first attribute value correspond to each first metadata. The search unit searches the plurality of first metadata on the basis of a correspondence between a second attribute indicating an item of an element included in newly acquired second metadata and a second attribute value corresponding to the second attribute and the first attribute and the first attribute value, and extracts corresponding metadata that is the first metadata corresponding to the second metadata.

[Problem] To ameliorate the deleterious effects of scattered radiation on contrast in radiographic images. [Solution] A frequency analyzer (42) performs a frequency analysis of a radiographic image, and generates band images expressing the frequency components in each frequency band. A reference image generator (43) generates a reference image expressing information associated with scattered radiation included in the radiographic image, and generates reference band images corresponding to the frequency bands from the reference image. A band image transformer (44) generates transformed band images by transforming the corresponding pixels of the reference band image and the band image in corresponding frequency bands. A synthesizer (46) generates a processed radiographic image in which the contrast has been transformed by synthesizing the transformed band images.
