Abstract
A current cross section searching unit identifies a current cross section corresponding to a scan plane by setting a group of provisional cross sections with respect to a tissue model corresponding to a target tissue, and calculating a degree of similarity between data of each provisional cross section and tomographic image data. An operation support information generating unit generates operation support information from difference information indicating a spatial relationship between the current cross section and a target cross section (corresponding to an observation cross section). The group of provisional cross sections set with respect to the tissue model is narrowed down based on a camera image.
Claims10
An ultrasonic diagnosis system, comprising:
- a former configured to form a tomographic image based on information obtained from a scan plane created by a probe;
- a searcher configured to identify a current model cross section corresponding to the scan plane by comparing the tomographic image to a group of provisional model cross sections set with respect to a tissue model reflecting a three-dimensional structure of a target tissue;
- and
- a generator configured to generate, based on the current model cross section, probe operation support information for causing the scan plane to approach an observation cross section in the target tissue.
An operation support method, comprising:
- a step of comparing a tomographic image, which is formed based on information obtained from a scan plane created by a probe, to a group of provisional model cross sections set with respect to a tissue model reflecting a three-dimensional structure of a target tissue, thereby identifying a current model cross section corresponding to the scan plane;
- and
- a step of generating probe operation support information based on a spatial relationship between the current model cross section and a target model cross section in the tissue model.
A non-transitory storage medium having stored therein a program for executing an operation support method in an ultrasonic diagnosis system, the program having:
- a function to compare a tomographic image, which is formed based on information obtained from a scan plane created by a probe, to a group of provisional model cross sections set with respect to a tissue model reflecting a three-dimensional structure of a target tissue, thereby identifying a current model cross section corresponding to the scan plane;
- and
- a function to generate probe operation support information based on a spatial relationship between the current model cross section and a target model cross section in the tissue model.
