01
Resolution gap
Conventional CT and MRI can leave clinically important middle- and inner-ear structures below the threshold for confident visualization.
High-resolution specialty CT
See what conventional CT cannot.
TROI-Imaging is developing a high-resolution region-of-interest CT platform for micro-anatomy—starting with the temporal bone and inner ear, where diagnostic details can approach the scale of hundreds of microns.
Conceptual TROI CT system
Early visual concept of the intended cobot-driven architecture.
Resolution demonstration
Microstructure becomes visible.
In this comparison, the TROI image resolves substantially finer structures than images simulated to match PCCT and CBCT resolution.
The image shows development-stage technical validation, not clinical performance.
The clinical problem
Small anatomy can create outsized diagnostic uncertainty.
02
Diagnostic uncertainty
Incomplete pathophysiology information can delay diagnosis, limit treatment planning, or push clinicians toward more invasive exploration in operating rooms (ORs).
03
Economic friction
Concurrent diagnosis and treatment can make OR time lengthy and less predictable, increasing total cost of care. Better pre-operative imaging can help close this gap.
The platform
High resolution where it matters.
Rather than extending ultra-high resolution across a large field of view, TROI concentrates imaging performance on a clinically relevant region of interest, supporting a compact system architecture and a path toward specialty workflows.
- Beachhead
- Temporal bone / otology imaging
- Clinical goal
- “Virtual tympanotomy” with TROI for safer, more efficient treatment and higher OR productivity.
- Care settings
- Hospitals, specialty centers, and high-volume ENT practices
- Expansion
- Additional small-region applications where resolution can change diagnosis or intervention
Provider value
Designed for value beyond the scan.
Imaging revenue
Specialty imaging can create a direct revenue stream within provider workflows, subject to coding, coverage, and payer requirements.
Avoided procedures
More definitive pre-operative imaging could reduce selected exploratory procedures where anatomy can be resolved non-invasively, making interventions targeted and purely therapeutic.
OR productivity
Better structural information before intervention may improve surgical planning, specialist efficiency, and use of operating-room capacity.
High-tech moat
A system-level imaging problem—not a single-component upgrade.
01
ROI imaging architecture
Geometry and acquisition are optimized around compact, high-value anatomy rather than general-purpose whole-body imaging.
02
Resolution trade-space
Detector performance, focal spot, geometry, reconstruction, motion, and dose must work together to preserve micro-anatomic information.
03
Robotic implementation
Cobot-driven design enables free-form trajectories to minimize radiation dose and support flexible patient positioning.
04
Proprietary know-how
System design, trajectory planning, geometry calibration, and decades of CT reconstruction research form a layered technical moat across the platform.
05
Application expansion
A platform strategy that could extend into other specialty applications where small-region resolution drives clinical and economic value.
