Abstract
Recently developed laser-scanner-receiver and mass storage devices have led to the feasibility of an electronic mass storage for x-ray pictures. Furthermore, such a system would combine both storage and automatic retrieval capabilities and make possible centralized storage facilities for large urban areas. Remote diagnosis and a variety of displays can also be easily incorporated into the system by using the Digital Data Service (DDS) introduced by Bell Laboratories. But the digital representation of a typical x-ray picture requires a rather large number of bits. Therefore, it is useful to inquire whether some data-reduction techniques can be used to make the system more effective.
In this chapter, the feasibility of three specific coding schemes for compact storage or fast transmission of radiographic images is investigated. These schemes are: the synthetic high system, the block coding system and the run-length coding system. The last two techniques are used for encoding bit planes. The dependence of the compression ratio on image resolution and the feasibility of adaptive coding of bit planes are also examined.
