Paper Abstract

We conceived a hybrid PACS which combines analogue and digital elements where it is required. We experimented a clinical application of the dynamic image utilizing the analogue element which is a feature of the hybrid PACS. With the analogue optical disk, dynamic image acquisition of 30 frames per second is possible and image recording is also possible with any modality of X-ray fluoroscopy function. In addition, X-ray dose to the patient is one-fifth to one-tenth compared with the conventional cine filming method while its still image is clear and a data acquisition to the PACS is easy. We applied this system to the areas of the otorhinolaryngology, orthopaedics and respiratory disease and could perform a various analysis of the disease status under natural conditions, also we found that this system is useful for judging an effect of a treatment as well as jugding a functional recovery after an operation and an effect of a rehabilitation. We are also planning to extend the application to the areas of the digestive system and the group examination from now on.
