Key components of SmartDose
SmartDose encompasses multiple features that work in tandem to reduce dose. Combined, these features provide a seamless workflow experience that prioritizes image quality, patient safety and dose efficiency.
LASER POSITIONING DEVICE
Allows for precise patient alignment without unnecessary exposure.
OBJECT DETECTED DOSE CONTROL (ODDC)
Detects patient anatomy in real time and dynamically adjusts exposure parameters and noise reduction filters, while also featuring an automatic pulse rate reduction during static imaging for optimal dose and image quality.
HIGH-SPEED AUTOMATIC DOSE REGULATION (ADR)
High speed X-ray exposure control for optimal exposure parameters, including tube voltage and tube current, ensuring excellent image quality at minimized dose levels.
ZAIP (ZIEHM ADAPTIVE IMAGE PROCESSING)
Advanced image processing algorithms and noise reduction filters that enhance contrast between soft tissue, bone, and metal to visualize even finest structures like guidewires.
VIRTUAL COLLIMATORS
For exposure-free positioning of slot and iris collimators.
BEAM FILTRATION
BeamFiltration2 is an advanced anti-scatter grid paired with an optimized beam hardening which selectively removes low-energy X-ray photons, thereby significantly reducing patient dose and improving image quality.
REMOVABLE ANTI-SCATTER GRID
Enhances image contrast by suppressing scattered radiation. For pediatric or low-dose applications, the grid can be removed to reduce entrance skin dose.
PREMAG
Digital pre-magnification of the live monitor image when switching to a different magnification mode, allowing the user to preview the field of view of the next image taken without additional exposure.
Additional considerations
In addition to advanced X-ray beam filtration, SmartDose leverages pulsed fluoroscopy to further minimize dose levels. Unlike continuous fluoroscopy, which delivers a constant beam, pulsed operation emits short, high-frequency bursts of X-rays. Ziehm Imaging’s monoblock generators produce well-defined pulses with minimal overlap and heat generation, enabling a significant dose reduction compared to continuous modes (Figure 1).
To optimize both image quality and dose efficiency, the system dynamically adjusts pulse rates: higher frequencies (e.g. 25 pps) are used during motion to avoid blur, while lower rates (e.g. 8 pps) are applied when anatomy is at rest. High-speed ADR ensures seamless transitions, while adaptive noise reduction filters are applied in real time to maintain image clarity at reduced dose levels.
Conclusion
Ziehm Imaging's SmartDose represents a paradigm shift in dose management for mobile C-arms. This technology not only upholds ALARA principles but also enhances clinical reliability and image quality. SmartDose empowers healthcare professionals to achieve superior outcomes with minimal health risk to patients, setting a new standard in interventional imaging.
