Frequently Asked Questions
Both platforms offer industry-leading 3D tomosynthesis with excellent dose efficiency. The Selenia Dimensions is a proven workhorse trusted by tens of thousands of facilities worldwide, while the 3Dimensions (Genius) platform is the newer flagship system with enhanced software features, faster acquisition speed, and improved workflow integration. Both are excellent choices; the selection depends on your facility's volume, budget, and preferences for newer technology versus field-tested reliability.
Software tomosynthesis upgrades are typically available for qualifying systems, though hardware requirements and licensing vary. Older analog systems cannot be upgraded. We recommend contacting our team with your specific system model for an assessment—our engineers can evaluate upgrade feasibility and cost-effectiveness compared to purchasing a refurbished tomosynthesis unit.
MQSA (Mammography Quality Standards Act) compliance ensures that mammography equipment meets federal standards for image quality, dose management, and safety. All mammography systems sold in the United States must maintain MQSA certification. AR-RAD conducts physicist testing and calibration for every unit we sell to guarantee MQSA compliance and regulatory readiness for your facility.
Installation typically requires 1-3 days depending on site preparation status and room modifications needed. Technologist and radiologist training is usually 2-5 days. We coordinate the entire process with your staff and can often overlap installation with training to minimize downtime. Our factory-trained technicians handle all setup and calibration work.
We offer flexible warranty packages ranging from 90 days to 5 years, plus optional service contracts that cover parts, labor, and preventive maintenance. Since we're an authorized service provider with nationwide coverage, your facility benefits from local support through our Lake Forest, California headquarters with the ability to serve any location across the US, Canada, and Mexico.
Yes. Our refurbishment process is rigorous: every detector is tested against ACR phantom standards, all mechanical systems are recalibrated, and new high-wear components are replaced. Many of our refurbished systems perform identically to new equipment at 40-60% of the cost, making them an excellent value for facilities with stable budgets.
Each Hologic mammography platform uses a specific detector assembly. Original Selenia FFDM systems use the ASY-00834 (standard cycle) or ASY-01389 (fast cycle) detectors. Selenia Dimensions systems use the PRD-00779 or PRD-01702 HDT detector depending on the configuration. Hologic 3Dimensions (Genius) systems use the PRD-04420 Clarity HD detector. These detectors are not interchangeable between platforms. Contact ARRAD with your system serial number and we will confirm the exact detector part number your system requires.
Our detector exchange program ships a quality-assured replacement detector to your facility before you return the failed unit. This minimizes mammography suite downtime by allowing your service engineer to install the replacement panel as soon as it arrives. After installation, you return the original detector using our provided shipping materials. Exchange pricing is typically lower than outright purchase, making this an attractive option for facilities managing equipment budgets.
Mammography flat-panel detectors degrade over time through several mechanisms. The amorphous selenium layer gradually crystallizes, reducing its ability to convert X-rays to electrical signals. Individual transistor elements in the TFT readout array can fail, creating dead pixels. Thermal cycling from daily power-on and power-off stresses electronic connections. Signs of degradation include increasing dead pixel counts, calibration instability, declining ACR phantom scores, and visible image artifacts. Regular quality control testing helps identify degradation trends early so replacement can be planned before clinical image quality is affected.
