Abstract
A system and method for automatically reducing false-positive nodule candidates associated with airways includes receiving a nodule candidate, testing for airway cavities connected to the candidate, and recognizing the candidate as a false-positive nodule candidate if it is connected to an airway cavity; where the testing may include perpendicular testing for airways that are relatively perpendicular to an examination plane and parallel testing for airways that are relatively parallel to an examination plane.
Claims34
A method for automatically reducing false-positive nodule candidates associated with airways, the method comprising:
- receiving a nodule candidate;
- testing for airway cavities connected to said candidate;
- and
- recognizing said candidate as a false-positive nodule candidate if it is connected to an airway cavity.
A system (100) for automatically reducing false-positive nodule candidates associated with airways, the system comprising:
- a perpendicular testing unit (170) for detecting an airway relatively perpendicular to an examination plane;
- and
- a parallel testing unit (180) in signal communication with the perpendicular testing unit (170) for detecting an airway relatively parallel to an examination plane.
A system for automatically reducing false-positive nodule candidates associated with airways, the system comprising:
- means for receiving a nodule candidate;
- means for testing for airway cavities connected to said candidate;
- and
- means for recognizing said candidate as a false-positive nodule candidate if it is connected to an airway cavity.
A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for automatically reducing false-positive nodule candidates associated with airways, the method steps comprising:
- receiving a nodule candidate;
- testing for airway cavities connected to said candidate;
- and
- recognizing said candidate as a false-positive nodule candidate if it is connected to an airway cavity.
