NAME
vrbreast − region growing of pectoral muscles.
SYNOPSISvrbreast if= df= bf= cf= az= of=
DESCRIPTION|
vrbreast |
performs the first stage region growing of pectoral muscles. The inputs are soft tissues (thoracic cavity set to 255), distance to fat outside the thoracic cavity, distance to the background(region outside the body), and thoracic cavity boundary. The output is the pectoral muscles segmented by this first stage of region growing. |
The first stage region growing is location-based and intends to detect all muscles that are not separated from the thoracic cavity by fat tissues. For each boundary voxel of the thoracic cavity, the 3D Euclidean distance to its nearest fat voxel is first calculated. Then any soft tissue voxels within this distance to the respective boundary voxel are considered as pectoral muscles.
