Abstract
A system for determining a dimension of an anatomical structure using an appropriate set of 2-D slice images obtained by scanning the anatomical structure, the system comprising: assembling apparatus for assembling the set of scanned 2-D slice images into a 3-D database; extracting apparatus for extracting an anatomical feature from the information contained in the 3-D database; specifying apparatus for specifying a measurement to be ade based on the extracted anatomical feature; and calculating apparatus for calculating the measurement so specified.
Claims3
A system for determining a dimension of an anatomical structure using an appropriate set of 2-D slice images obtained by scanning said anatomical structure, said system comprising:
- assembling apparatus for assembling said set of scanned 2-D slice images into a 3-D database;
- extracting apparatus for extracting an anatomical feature from the information contained in said 3-D database using an additive process;
- specifying apparatus for specifying a measurement to be made based on said extracted anatomical feature;
- and
- calculating apparatus for calculating the measurement so specified;
- wherein said anatomical feature is the centerline of said anatomical structure, and wherein said system further comprises a cumulative sum table derived from said centerline, and said calculating apparatus utilizes said cumulative sum table to determine a length measurement by calculating the distance of the centerline of any two given points.
A system for determining a dimension of an anatomical structure using an appropriate set of 2-D slice images obtained by scanning said anatomical structure, said system comprising:
- assembling apparatus for assembling said set of scanned 2-D slice images into a 3-D database;
- extracting apparatus for extracting an anatomical feature from the information contained in said 3-D database using an additive process;
- specifying apparatus for specifying a measurement to be made based on said extracted anatomical feature;
- and
- calculating apparatus for calculating the measurement so specified;
- wherein said system comprises a cumulative sum table derived from said anatomical feature, and further wherein said calculating apparatus utilizes said cumulative sum table to determine a volume measurement by calculating the distance of the centerline of any two given points.
A method for determining a length dimension of an anatomical structure using an appropriate set of 2-D slice images obtained by scanning said anatomical structure, said method comprising the steps of:
- (1) assembling said set of scanned 2-D slice images into a 3-D database;
- (2) extracting An anatomical feature from the information contained in said 3-D database, said anatomical feature comprising the centerline of said anatomical structure, and generating a cumulative sum table derived from said centerline;
- (3) specifying a measurement to be made with respect to said cumulative sum table based on said extracted anatomical feature;
- and
- (4) calculating the measurement so specified by utilizing said cumulative sum table to a length measurement by calculating the distance of the centerline of any two given points.
