Abstract
A blood flow dynamic analysis apparatus for analyzing the dynamic state of a blood flow of a subject using data about a plurality of frame images acquired from the subject with a contrast agent injected therein, includes a map creation device for creating maps each indicative of a characteristic amount related to the dynamic state of the contrast agent or the blood flow, based on the data about the frame images, an unaffected side detection device for detecting an unaffected side of the subject from within each of the maps, and a display condition determination device for determining a display condition used when each of the maps is displayed, based on pixel values of pixels existing in the unaffected side in the map.
Claims19
A blood flow dynamic analysis apparatus configured to analyze a dynamic state of a blood flow of a subject using data about a plurality of frame images acquired from the subject with a contrast agent injected therein, the blood flow dynamic analysis apparatus comprising:
- a map creation device configured to create a plurality of maps each indicative of a characteristic amount related to the dynamic state of the contrast agent or the blood flow, based on the data about the plurality of frame images;
- an unaffected side detection device configured to detect an unaffected side of the subject from within each of the plurality of maps, wherein the unaffected side is free of an anomaly;
- and
- a display condition determination device configured to determine a display condition used when each of the plurality of maps is displayed, based on pixel values of pixels existing in the respective unaffected side in each of the plurality of maps.
A magnetic resonance imaging system comprising:
- a coil assembly configured to emit at least one pulse;
- a reception coil configured to receive a magnetic resonance signal emitted by a subject in response to the at least one emitted pulse;
- a controller configured to receive the magnetic resonance signal from the reception coil, the controller further configured to analyze a dynamic state of a blood flow of a subject using data about a plurality of frame images generated using the magnetic resonance signal, the controller comprising:
- a map creation device configured to create a plurality of maps each indicative of a characteristic amount related to the dynamic state of contrast agent or the blood flow, based on the data about the plurality of frame images;
- an unaffected side detection device configured to detect an unaffected side of the subject from within each of the plurality of maps, wherein the unaffected side is free of an anomaly;
- and
- a display condition determination device configured to determine a display condition used when each of the plurality of maps is displayed, based on pixel values of pixels existing in the respective unaffected side in each of the plurality of maps.
A program installed in a controller of a blood flow dynamic analysis apparatus for use in analyzing a dynamic state of a blood flow of a subject using data about a plurality of frame images acquired from the subject with a contrast agent injected therein, the program including instructions configured to cause the blood flow dynamic analysis apparatus to function as:
- a map creation device for creating maps each indicative of a characteristic amount related to the dynamic state of the contrast agent or the blood flow, based on the data about the plurality of frame images;
- an unaffected side detection device for detecting an unaffected side of the subject from within each of the plurality of maps, wherein the unaffected side is free of an anomaly;
- and
- a display condition determination device for determining a display condition used when each of the maps is displayed, based on pixel values of pixels existing in the respective unaffected side in each of the plurality of maps.
