A method of extraction and graphical presentation of diaphragms for an observation system with an intuitive control.
The observation of movement of diaphragm is one of important methods for diagnosis of lung diseases. So, we have been developing an observation system which generates a movie of pseudo solid images using numerous sagittal and frontal MRI images and the movie on a flat panel monitor. And also the direction of the solid images can be changeable dynamically by operator's tilting its monitor, which means the intuitive control. We refined our observation system and developed a method to extract a diaphragm boundary and a new presentation to display the boundary of a diaphragm and body outlines to observe and discriminate their movement.
