Abstract
A system and method for automatic contrast enhancement for contouring. The system and method including displaying a volumetric image slice to be analyzed, receiving a delineation of a target anatomic structure in the volumetric image slice, identifying a region of interest based upon an area being delineated in the volumetric image slice, analyzing voxel intensity values in the region of interest and determining an appropriate window-level setting based on the voxel intensity values.
Claims16
A method for automatic contrast enhancement for contouring, comprising:
- displaying a volumetric image slice to be analyzed;
- receiving a user delineation of a target anatomic structure in the volumetric image slice;
- identifying a region of interest based upon an area being delineated in the volumetric image slice, wherein if the user delineation is not received, the method identifies the entire volumetric image slice as the region of interest;
- analyzing voxel intensity values in the region of interest;
- and
- determining an appropriate window-level setting based on the voxel intensity values,
- wherein the region of interest is continuously identified, the voxel intensity values of the region of interest analyzed and the appropriate window-level setting determined as the target anatomic structures is delineated.
A system, comprising:
- a display displaying a volumetric image slice to be analyzed;
- a user interface capable of accepting a user delineation of a target anatomic structure in the volumetric image slice, wherein if the user delineation is not received, the system identifies the entire volumetric image slice as the region of interest;
- and
- a processor identifying a region of interest based on the user delineation and analyzing voxel intensity values of the region of interest to determine an appropriate window-level setting, wherein the region of interest is continuously identified, the voxel intensity values of the region of interest analyzed and the appropriate window-level setting determined as the target anatomic structures is delineated.
A non-transitory computer-readable storage medium including an executable program stored thereon, wherein the program instructs a processor to perform operations comprising:
- displaying a volumetric image slice to be analyzed;
- receiving a user delineation of a target anatomic structure in the volumetric image slice;
- identifying a region of interest based upon an area being delineated in the volumetric image slice, wherein if the user delineation is not received, the processor identifies the entire volumetric image slice as the region of interest;
- analyzing voxel intensity values in the region of interest;
- and
- determining an appropriate window-level setting based on the voxel intensity values,
- wherein the region of interest is continuously identified, the voxel intensity values of the region of interest analyzed and the appropriate window-level setting determined as the target anatomic structures is delineated.
