X-ray Hardware Methodologies
Contrast of X-ray Hardware Methodologies
Instrumentarium Digora Optime phosphor plate reader
- Easy for patient to tolerate and are the same size as traditional film, sizes 0-3
- Are reusable for extended periods of time (year or greater depending on use)
- Less re-train time for staff
- Uses traditional x-ray holders, such as Rinn® Snap-A-Ray® or Rinn
- Work well with both long cone and short cone devices and techniques
- Wider dynamic range or exposure latitude than direct sensor
- Reduced initial cost and replacement costs for plates ($40 vs $3000)
- Unlimited manipulation and positioning of image receptor
- Can be damaged if care is not taken
- Plates need to be replaced approximately once per year, depending on number of images captured
- Need to re-wrap plates into sterile packets before each use
- Slower, more complex workflow for staff
- Examples: Soredex-OpTime, Gendex-DenOptix, Kodak-Orex
SUNI Intraoral Sensors, numbers 0, 1, and 2
Direct Sensor or solid-state systems advantages
- Image appears immediately on PC screen
- Redo's are immediate, no waiting for processing
- Working "films" for endo are much quicker
- Image quality is excellent (better than PSP)
- Better diagnostic capabilities as you can adjust brightness, contrast, sharpness, etc.
- SuniRay boasts extremely low radiation .04-.06 ms, 1/2 of most other digital sensors
- Faster workflow for staff
- Image quality can be easily distorted by older x-ray heads/generators which lack proper settings by patient age, area of the mouth, gender, etc.
- Staff re-training is required to adapt to sensor dimensions when placed in the mouth
- Limited sizes available
- Higher costs
- Cords which connect to the PC can present a hazard for patients and staff
- Due to cost, a shortage of available sensors may be experienced during times when many x-rays are to be captured
- Discrepant diagnostic results if system and digital picture archiving system are not calibrated properly
- Examples: Dexis Digital X-ray System, Schick CDR® or CDR wireless, Soredex
Digital Radiography Implementation Costs
The initial costs associated with the adoption of digital radiography can seem high when viewed as a single dollar amount. But cost savings should be evident immediately upon implementation.
The chart below shows a comparison of costs for film-based x-rays comparing the cost associated with the use of digital radiography, specifically PSP digital radiography. This example assumes all x-rays are taken by a dental assistant, if hygienists are taking recall BWX, labor costs would be increased.
Approximate "film-based" x-ray expenditures for a single doctor in one-year and five-year timeframes.
