Development of a three-dimensional computer-generated lung segment overlay chart

Knowledge of segmental anatomy improves accuracy and precision in interpretation of perfusion lung studies. We report here a computer-oriented method that allows creation of an 'anatomic wire line diagram overlay of pulmonary segments' (AWLDOPS) for use as reference diagrams to more accurately localize segmental lung scan perfusion defects using MedImage Medview software. Superimposition of AWLDOPS and manipulation of the perfusion images is achieved so as to co-register images in size, obliquity and rotation.
