World Digital Radiography (DR) Markets
Frost & Sullivan, Feb 2004
Increasing Implementation of PACS Pushes Digital Radiography into High Gear
As an emerging technology, digital radiography (DR) has witnessed phenomenal success and overcome initial hurdles, such as inefficient manufacturing, production bottlenecks, exorbitant prices, and low customer interest. Increasing proliferation of picture archiving and communications systems (PACS) is driving the adoption of complementary DR technology that assists in achieving cost-cutting and quality improvement goals. Deployment of DR in a PACS environment provides comprehensive and cost-effective image management solutions that could replace film-based and computed radiography systems. DR also eliminates delays and inefficiencies inherent in film development, increasing patient throughput and allowing hospitals to economize on space and deployment of radiology employees.
This research analyzes the digital radiography markets and different types of underlying technologies such as charge-coupled device (CCD) cameras, amorphous silicon detectors, and amorphous selenium detectors. A comprehensive coverage of key market drivers, restraints, and challenges assists in creating focussed marketing and business plans. Strategic recommendations enable participants to harness the benefits of the latest developments and emerging opportunities in this market.
Future Price Reduction Set to Stimulate Wider Acceptance of DR Systems
High-priced DR systems with flat-panel detectors were initially introduced to cater to large hospitals and medical centers. However, with the market expanding beyond the early-adopter segment, competitively priced DR systems are expected to gain widespread popularity and gradually replace computed radiography. Economies of scale and increased production volumes for flat-panel detectors are signalling cost maturation and ultimately more affordable DR systems accessible to smaller hospitals and outpatient facilities, explains the analyst.
However, extremely low-prices, though competitive in the short run, do not necessarily boost unit shipments. This assumes greater significance when dealers and distributors become involved, since manufacturers typically lose 30 to 40 percent of the sales proceeds to revenue sharing with distributors. A balanced pricing strategy of five to ten percent below the market average is considered optimum and stimulates sustainable revenue growth in the long run.
High-performance Imaging Combined with Lower Radiation Doses Spurs Growth of DR
The use of low-radiation dosage to produce superior quality X-ray images is a significant achievement that catapults DR systems ahead of general radiography screen-film systems. Many DR models operate at about half the radiation dosage conventional X-ray systems require for routine radiological examinations, notes the analyst. Considering the health risks attached to radiation exposure, low-radiation doses combined with equivalent imaging power may boost the sales of DR systems.
Innovative technology that incorporates several value-added features improves diagnostic and clinical performance of DR systems in the medical imaging environment. For instance, the tissue equalization feature permits a single high-quality display of both low- and high-density tissues. Dual energy subtraction is a sophisticated imaging technique that allows different attenuation characteristics of soft tissue and bone to be individually processed. This may prove to be a high-potential technology since it eliminates overlying structures and replaces frequently obscured pathology with high-clarity images.
