Why DC-Air® stands apart
DC-Air® delivers freedom from cables so clinicians can move confidently and capture diagnostic images without physical constraints.
Direct-conversion technology bypasses the traditional scintillator, preserving information captured at the sensor and supporting image accuracy.
Single-crystal direct conversion
Captured, not synthesized.
Conventional scintillator sensors convert X-rays to light, then light to signal. DC-Air® converts each photon directly to charge at the point where it lands.
No scintillator. No fiber-optic plate. The source workflow applies brightness and contrast rather than sharpening.
Objective image sharpness
Superior Modulation Transfer Function (MTF)
MTF is an objective measure of how well an imaging system preserves contrast and sharpness across spatial frequencies. DC-Air® reports values greater than 70% at 5 lp/mm and over 40% at 10 lp/mm.
>70%MTF at 5 lp/mm
>40%MTF at 10 lp/mm
| Sensor | Performance summary |
|---|---|
| DC-Air® (26µm) | Highest performance in both 10% and 50% MTF measures, delivering industry-best diagnostic clarity. |
| Carestream RVG 6200 (19µm) | Moderate performance with solid clarity, but trails behind in high-frequency resolution. |
| DEXIS Ti2 / Titanium (22µm) | Strong mid-range clarity with CleanCapture™ noise reduction, but lacks the consistent high-frequency sharpness of DC-Air®. |
| Gendex GXS-700 (20µm) | Competent mid-range performance, particularly at lower MTF thresholds. |
| Planmeca ProSensor HD / ProSensor (28µm) | Moderate performance across both MTF levels, though lacking finer spatial clarity. |
| Schick 33 Standard (30µm) | Underperforms at both resolution thresholds compared with newer-generation sensors. |
| Schick 33 High Resolution (15µm) | Strong showing at 10% MTF due to smaller pixel size, but falls off at 50% MTF. |
| Sirona XIOS XG Supreme (30µm) | Trails significantly in both resolution and contrast retention. |
| Dentalmind / Hamamatsu (26µm) | Comparable to older Gendex and Schick sensors, but short of DC-Air® consistency. |
| Schick 2000 (40µm) | Legacy model with the lowest clarity of the comparison group. |
The published FTG comparison presents DC-Air® as retaining stronger contrast across diagnostically useful frequencies for evaluating caries, periodontal structures and periapical anatomy.
Dentist designed
Zero Profile® Alignment System
Precision-engineered holders support sensor positioning and patient comfort. DC-Air® also works with standard Size 2 holder systems.
Anterior
For positioning anterior images.
Posterior
For molar and canine posterior images.
Endodontic

Head-to-head
DC-Air® vs. Leading Competitors
Four product decisions distinguish the DC-Air approach from conventional wired and indirect-conversion sensors.
Superior IA
Direct conversion avoids scintillator blur and preserves diagnostic information.
Enhanced Patient Experience
A thinner cable-free profile reduces positioning restrictions.
Workflow Efficiency
True wireless operation removes cable management between operatories.
Long-Term Reliability
Removing the cable eliminates a common sensor failure point.
Image Accuracy
What is IA?
IA describes how precisely a sensor reproduces the true anatomical structures of teeth, bone and soft tissue with minimal distortion, noise or loss of diagnostic detail.
Sharpness & Resolution
Visibility of fine details including root tips, caries and trabecular bone.
Contrast & Gray Scale
Differentiation of subtle changes in tissue density.
Geometric Accuracy
Minimal distortion or magnification for true-to-scale anatomy.
Noise Reduction
Less electronic or scatter grain obscuring diagnostic features.
Consistency
Reliable reproduction across patients and settings.
Why it matters
Accurate image information supports diagnosis, reduces false positives and negatives, and provides a stronger foundation for human and AI interpretation.
Who Has the Best IA?
Direct-conversion sensors such as DC-Air® convert X-rays directly into an electronic signal without the scintillator and optical-fiber stages that can scatter information. FTG positions that simpler signal path, supported by the MTF comparison above, as the foundation for more accurate diagnostic images.
