What We Offer

Imaging Endpoint Definition & Standardization

What We Do:

We support you in defining the measurement methods that lead to your imaging endpoints, and advise you on the selection of relevant parameters. In doing so, we ensure that the endpoints are clinically meaningful, measurable, and justifiable for your specific study — grounded in current literature and established standards. Please note: We do not develop study protocols or regulatory documentation, and we are not involved in direct communication with regulatory authorities.

AI-Based Quantitative Radiographic Analysis

What We Do:

Extract quantitative imaging endpoints, device performance metrics (fusion, subsidence, alignment), and morphoanatomical measurements with precision. Our AI-assisted tools accelerate analysis by 50% compared to traditional manual workflows while maintaining accuracy and reproducibility.

Radiologist Network for Qualitative Image Analysis

What We Do:

Independent blind central image review conducted by experienced, board-certified radiologists. Direct access to senior experts—not ticket queues or account managers. Our network ensures unbiased evaluation with standardized protocols and responsive, personalized support.

Image Quality & Site Compliance Monitoring

What We Do:

Every image is reviewed to ensure consistency in quality and protocol compliance. Real-time, proactive feedback to sites prevents costly downstream issues—unlike traditional reactive approaches that discover problems only after expensive rework is required.

Clinical Trial Imaging Infrastructure

What We Deliver:

Proprietary image management system with native EDC integration—imaging data lives within your study database, not in separate silos, including imaging eCRFs. No time-consuming reconciliation or manual data transfers. Full audit trail and regulatory compliance built in.

Imaging Review Charter Development

What We Deliver:

Agile charter development tailored to your trial's unique needs—imaging modalities, assessment methods, and protocols for ethics/regulatory submission. Based on literature review and regulatory guidance, with flexibility to adapt mid-study without enterprise bureaucracy.

We are your imaging experts for orthopedics and spine trials.

Our experience & expertise

Spinal image analysis for clinical trials, registries, and research.

We have extensive experience designing and executing clinical studies with imaging endpoints for all major spinal therapies, including fusion, motion preservation, and deformity correction—from early feasibility through post-market surveillance.

Our spinal fusion experience spans cervical and lumbar procedures with allograft, autograft, and bioactive implant materials (hydroxyapatite, demineralized bone matrix), utilizing standardized protocols across X-ray, CT, and MRI modalities.

We support IDE, 510(k), and PMA submissions with regulatory-grade measurements of fusion status, segmental motion, alignment, subsidence, and device performance—all delivered with faster turnaround and seamless EDC integration compared to traditional core labs

Hip implant component positioning and performance analysis.

We have extensive experience supporting total hip arthroplasty (THA) device manufacturers with radiographic analysis throughout product development—from primary THA through revision procedures and across post-market surveillance.

Our team has developed and validated proprietary 2D-3D image registration techniques that extract precise implant positioning metrics (acetabular cup inclination and anteversion) and linear wear measurements from standard clinical radiographs. This methodology has been applied across multiple clinical studies supporting regulatory submissions, enabling device safety and effectiveness assessments without specialized imaging protocols.

Our THA expertise spans:

  • Primary and revision arthroplasty procedures
  • Component positioning analysis for conventional and robotic-assisted surgeries
  • Long-term migration assessment (femoral stem subsidence, acetabular cup migration)
  • Polyethylene liner wear quantification
  • Osseointegration evaluation of acetabular components
  • Device integrity monitoring and radiolucency detection
 

We’ve supported THA device manufacturers in generating robust, regulatory-grade evidence across diverse implant designs, bearing surfaces, and surgical approaches.

Knee implant positioning and performance analysis.

We have extensive experience supporting total knee arthroplasty (TKA) device manufacturers with comprehensive radiographic analysis throughout product development—from primary TKA through revision procedures and post-market surveillance.

Our validated methodology enables precise quantification of critical biomechanical and performance endpoints from standard clinical radiographs, including:

  • Alignment assessment: Hip-knee-ankle (HKA) angle, mechanical and anatomical leg alignment
  • Component positioning: 6 degrees of freedom (6-DoF) analysis for femoral and tibial components
  • Component alignment: Coronal and sagittal plane positioning relative to anatomical landmarks
  • Performance monitoring: Polyethylene wear quantification and implant migration/subsidence tracking over time
 

This approach has been applied across multiple clinical studies supporting regulatory submissions for both conventional and robotic-assisted TKA procedures, providing the regulatory-grade evidence manufacturers need across diverse regulatory pathways.

Sample radiographic analyses

Medical image analysis for clinical trials in orthopedics and spine

The FDA-approved Functional X-Ray Analysis software (FXA) of our imaging core lab is capable of automatically evaluating over 150 radiographic parameters of the spine, hip, or knee. The reproducibility of the measurements is on file with FDA 510(K).

Explore some of our most popular automatically assessable quantitative radiographic parameters below.

Spine

Range of Motion (RoM)

The Angular Motion/Range of Motion (RoM) is a quantitative parameter used to evaluate spinal fusion.

It is measured as the angular difference of two adjacent vertebrae during the flexion and the extension posture of a patient and is reported as an absolute value in degrees (°). RAYLYTIC’s FXA software has been shown to measure RoM 15 times more precisely than experienced physicians (Schulze et al., J Biomech 2011).

Translational AP Motion

A further quantitative parameter used to assess spinal fusion, translational AP motion or instability is expressed as the difference in listhesis in flexion minus listhesis in extension. 

Values are given in millimeters or in degrees. Positive values indicate spondylolisthesis, while negative values indicate retrolithesis.

Hip

Cup Inclination and Anteversion

Cup incliniation refers to the angle in degrees (°) of the cup surface against the horizontal (medio-lateral) axis. 

Cup anteversion is the angle in degrees (°) of the cup surface against the cup symmetry axis in the frontal plane. 

To assess these parameters, CAD models of the implants are required.

Hip Implant Migration

Migration of the hip stem relative to the femur is measured cranial-caudal (mm) and medial-lateral (mm). Angular change is measured in degrees.

Migration of the hip cup relative to the pelvis is also meausered cranial-caudal (mm)  and medial-lateral (mm).

Implant wear

Wear is a key factor affecting the lifespan of orthopedic implants and refers to the gradual erosion and subsequent production of microparticulate debris, which can cause aseptic loosening.

In the past, quantifying wear has required additional invasive procedures. RAYLYTIC uses a validated, highly accurate 2D-3D registration technique to determine wear in standard clinical X-rays of knee replacements (Lutter et al. 2021, German Congress of Orthopaedics and Traumatology).
