Abstract
Apparatus and methods are described for receiving into at least one processor a set of images of blood vessels of a subject. A road map of the subject's blood vessels is generated, by automatically (a) deriving at least one image from the set of images of the blood vessels, based upon visibility of at least a portion of the blood vessels in the set of images, and (b) in the derived image, determining a location of edge lines of at least some of the portion of the blood vessels in the image. An output is generated by the processor, based on the road map. Other embodiments are also described.
Claims31
A method, comprising:
- receiving into at least one processor a set of images of blood vessels of a subject;
- generating a road map of the subject's blood vessels, by automatically:
- deriving at least one image from the set of images of the blood vessels, based upon visibility of at least a portion of the blood vessels in the set of images;
- and
- in the derived image, determining a location of edge lines of at least some of the portion of the blood vessels in the image;
- and
- generating an output by the processor, based on the road map.
Apparatus, comprising:
- an image-acquisition device configured to acquire a set of images of blood vessels of a subject;
- a display;
- and
- at least one processor, comprising:
- image-receiving functionality configured to receive the set of images into the processor;
- image-derivation functionality configured to automatically derive at least one image from the set of images of the blood vessels, based upon visibility of at least a portion of the blood vessels in the set of images;
- and
- edge-line-determination functionality configured to automatically generate a road map by determining a location of edge lines of at least some of the portion of the blood vessels in the derived image;
- and
- display-driving functionality configured to drive the display to display an output to a user based upon the road map.
A method for use with blood vessels of a subject that move cyclically, in accordance with a motion cycle, comprising:
- receiving into at least one processor a set of images of the blood vessels;
- automatically, deriving at least one image from the set of images of the blood vessels, based upon:
- (a) timing of acquisition of images from the set of images with respect to the motion cycle, and
- (b) visibility of at least a portion of the blood vessels in the set of images;
- generating a road map based upon the derived image;
- and
- generating an output based upon the road map.
Apparatus for use with blood vessels of a subject that move cyclically, in accordance with a motion cycle, comprising:
- an image-acquisition device configured to acquire a set of images of the blood vessels;
- a display;
- and
- at least one processor, comprising:
- image-receiving functionality configured to receive the set of images into the processor;
- image-derivation functionality configured to automatically derive at least one image from the set of images of the blood vessels, based upon:
- (a) timing of acquisition of images from the set of images with respect to the motion cycle, and
- (b) visibility of at least a portion of the blood vessels in the set of images;
- road-map-generation functionality configured to generate a road map based upon the derived image;
- and
- display-driving functionality configured to drive the display to display an output to a user based upon the road map.
A method for imaging a portion of a body of a subject that moves as a result of cardiac cyclic activity of the subject and that also undergoes additional motion that is at least partially a result of a respiratory cycle of the subject, the method comprising:
- identifying a given phase of the cardiac cyclic activity;
- generating a stabilized set of image frames of the portion of the subject's body
- by outputting a set of image frames corresponding to image frames of the portion acquired during the given phase, and
- by image tracking at least the set of image frames to reduce imaged motion of the portion of the subject's body associated with the additional motion;
- and
- displaying the tracked set of image frames of the portion of the subject's body.
