Automated scan plane planning is expected to improve MRI scanner usability and provide consistent scan plane prescriptions which are useful for follow-up examinations. However, a landmark degenerated by formation of a lesion such as an intervertebral disc in the case of hernia patient is difficult to detect because shape and properties of tissue greatly deviate from normal cases. In this study, we have proposed combining adaptive boosting and active shape model to detect intervertebral discs robustly for automated scan plane planning of spine MRI.
