Abstract :
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.
