What Physicians Need to Know

DICOM Support & Standards
Cydar EV Maps complies with DICOM voluntary standards (ACR/NEMA. Digital Imaging and Communication in Medicine). CT scans are imported in DICOM format via the 'Cydar Gateway' software.
PACS Integration Method
Offers flexible levels of integration with PACS systems. CT scans can be imported directly from Hospital PACS into a secure Hospital Vault. The Cydar Gateway (CG) Application sits on a VM in the Hospital Network, requiring a single outbound connection to the cloud-based Hospital Vault, with no inbound connections permitted.
Reading Room Workflow Impact
Designed to streamline workflows, automate tasks, and simplify processes, reducing administrative burdens. Provides real-time, data-driven insights and enables collaboration across specialties. Offers real-time, fully integrated 3D visualization during endovascular aortic repair (EVAR) procedures, enhancing spatial information and precision. Facilitates pre-procedure planning, image-guided navigation, and post-operative review. Features include map overlay, auto and semi-auto adjustments for patient/equipment movement and soft tissue deformation, and surgical procedure recording for review.
AI Model Architecture (deep learning approach)
An AI-driven technology leveraging cloud computing, computer vision, and machine learning. Includes 2D and 3D Image Deep Learning, with automated 2D-3D image registration and verification. Pre-operative processing uses a deep learning algorithm for segmenting aortoiliac arterial anatomy. Utilizes fully-automatic computer vision to track patients during X-ray guided surgery. The Aortic Volume Assessment (AVA) feature uses AI to automatically estimate aneurysm volume.
Processing Speed (per study)
A 3D virtual map can be generated and ready for use within u226430 minutes between CT scan upload and surgery for emergency cases. The system can detect vertebrae and match them with an aortic overlay in five seconds. Auto-registration is accelerated to provide the overlay at the touch of the fluoroscopy pedal.
FDA Clearance Pathway (510k/De Novo)
Cydar EV Maps is U.S. FDA 510(k) cleared. Cydar EV (Series B) received 510(k) clearance (K212442) on December 3, 2021, as substantially equivalent to Cydar EV Series A (K160088) and Endosize (K141475). Cydar EV (Series A) received its initial 510(k) clearance (K160088) on July 7, 2016.
Supported Modalities (CT/MRI/X-ray/US)
Utilizes pre-operative CT scans, overlaying 3D vessel anatomy onto live X-ray fluoroscopy images. Compatible with any existing X-ray system, including both fixed and mobile C-arms. Optimal CT scans should have a slice thickness of u22641.0 mm; scans >3mm are considered too low resolution.
Sensitivity & Specificity Data
Clinical studies demonstrate significant reductions in X-ray fluoroscopy screening time (mean 35% reduction), radiation exposure (e.g., 80 mGy in Cydar group vs. 142 mGy in control, 2002 mGy reduction), and iodinated contrast agent use (mean 41% reduction, 77 mL decrease). Associated with a reduction in average operating time (e.g., one-hour reduction, 26 minutes reduction in fluoroscopy time). One study reported no significant differences in adverse events, endoleaks, or additional procedures. The ARIA trial is a multi-center randomized controlled trial assessing clinical, technical, and cost-effectiveness.
RSNA/ACR Validation
Complies with DICOM voluntary standards (ACR/NEMA. Digital Imaging and Communication in Medicine). The ARIA trial is a multi-center randomized controlled trial evaluating the system's efficacy.
Physician Tip

Leverage Cydar EV Maps for enhanced real-time 3D visualization during endovascular procedures to improve precision and reduce reliance on 2D fluoroscopy. Utilize the system's capabilities to significantly reduce patient and staff exposure to radiation and nephrotoxic contrast agents. Capitalize on streamlined workflows and shorter procedure times to optimize operating room efficiency. Maximize the benefit of patient-specific 3D maps for comprehensive pre-operative planning, especially for complex cases. Ensure high-quality pre-operative CT scans (ideally u22641.0 mm slice thickness) for optimal system performance and accuracy.

Cydar EV Maps is a cloud-based platform designed for easy integration into existing hospital IT infrastructure. It offers flexible PACS integration via a secure Cydar Gateway application, which resides within the hospital network and uses a single outbound connection to the cloud-based Hospital Vault, simplifying IT security. The system is agnostic, compatible with any existing X-ray system (fixed and mobile C-arms). Automatic software updates are provided, and data security is maintained through ISO 27001 and SOC II Type II equivalent standards. 24/7 online support is available to assist with integration and usage.

Frequently Asked Questions

Cydar EV Maps is a cloud-based software that uses AI, computer vision, and machine learning to create patient-specific 3D anatomical maps for endovascular procedures. It integrates pre-operative planning with real-time intra-operative navigation, overlaying detailed 3D anatomy onto live fluoroscopy to improve precision. This augmented reality view aims to reduce radiation exposure for patients and staff, decrease contrast agent use, and shorten procedure times.
Cydar EV Maps has received FDA 510(k) clearance in the US and a CE mark in the EU/UK, certifying it as a Software-as-a-Medical Device. Patient data is stored in a dedicated Hospital Vault, with access controls set by the hospital, and the system is designed to be GDPR-compliant, relying solely on existing patient data without introducing new imaging.
Cydar EV Maps is designed to be compatible with any existing X-ray system, providing a detailed 3D enhanced reality view of anatomy. It functions as a Software-as-a-Service product, accessed via a secure web browser, with a Cydar Appliance (an off-the-shelf PC with a video frame grabber) handling intra-operative fusion imaging.
Cydar EV Maps is not recommended for patients under 18 due to unknown performance in immature vertebral anatomy. Pre-operative maps show static anatomy, so it is mandatory to check real-time anatomy with a suitable imaging technique, such as contrast angiography, before deploying any invasive medical device, as vessels can deform during procedures.
Unlike traditional 2D fluoroscopy, Cydar EV Maps provides real-time, fully integrated 3D visualization, addressing the loss of spatial information common in minimally invasive procedures. Its AI-driven auto-registration and ability to adjust for patient and soft tissue movement aim to overcome limitations of older fusion systems that require re-registration after patient movement or anatomical deformation.
While specific pricing details are not publicly disclosed, Cydar EV Maps operates as a Software-as-a-Service (SaaS) product, implying a subscription-based model. This typically includes access to the cloud-based software, ongoing updates, and 24/7 online technical support. Additional services like integration support and specialized training would likely be part of the overall package.
All users are required to complete the Cydar EV Maps training program prior to use, with access provided via links or QR codes. Cydar offers 24/7 online support for technical assistance, and the cloud-based nature of the platform allows for continuous product performance improvement and enables new features and insights.
