smart surgon asistant system in
ortheopedice surgery
Introduce
This system is an intelligent, sterile-friendly image manager for the operating room that unifies MRI, fMRI, DTI, and tumor maps into a single, surgeon-centric workspace. Using voice and gesture controls, the surgeon navigates 2D and 3D views, manages layers in real time, and makes faster, more confident decisions—at a significantly lower cost than comparable foreign systems.
Key Capabilities
Simultaneous brain + tumor display with the option to toggle the tumor layer on/off.
Multi-angle slicing (axial/coronal/sagittal and oblique) for precise margin assessment.
Preserves the 3D tumor model even while slicing through the brain volume.
Dual 2D/3D visualization for quicker, safer interpretation.
Image editing tools: adjust window/level (brightness/contrast), rotate/flip, on-image notes, ruler, and angle measurement.
Maintain and display DTI tracts and fMRI activations while cutting through brain cross-sections.
Direct PACS connectivity (DICOM) for secure, rapid image retrieval.
Real-time 3D rendering of fMRI, DTI, and tumor from multiple viewpoints with layer management (show/hide, transparency, ordering).
Touch-free, sterile interaction via voice and motion commands, removing the need for an intermediary operator and improving OR hygiene.
Clinical & Operational Benefits
Higher accuracy and surgeon focus through direct, sterile image control.
Reduced intraoperative time by eliminating the back-and-forth with a human intermediary.
Substantial cost savings in acquisition and maintenance versus imported alternatives.
In short: sharper visuals, faster interaction, safer workflow—so the path to a surgical decision is as quick as a single voice command.
DTI & FMRI
Through this software, the doctor separates the cells and nerve fibers before the surgery in the treatment design stage. To perform surgery during the operation without the slightest damage to the brain.
Smart Assistant Surgeon
Assists the surgeon during surgery in the operating room. The surgeon can access medical images without touching the mouse or keyboard with voice and motion commands. These images are displayed in two and three dimensions.
DAR4DCT
The final product assists the physicist in the treatment design phase. The software simulates the amount of tumor movement in the lungs during inhalation and exhalation.
From Academic Idea to OR-Ready Solution
The initial concept began as a student thesis tackling a clear challenge: give neurosurgeons a fast, sterile, hands-free way to manage MRI/fMRI/DTI and tumor maps during surgery. The academic prototype proved the approach and paved the way for a real clinical product.
Next, Bita Negar Afzar transformed the idea into a mature clinical software platform:
Seamless integration with PACS using the DICOM standard
Real-time 2D/3D rendering with multi-planar/oblique slicing and layered display of tumor, fMRI, and DTI
Touch-free control (voice and gesture) to preserve sterility and surgeon focus
Precise editing and measurement tools (window/level, rotation, annotations, ruler, angle)
To optimize performance in the operating room, the team designed a dedicated mobile cart (trolley)—turning the software into a complete solution:
GPU-powered workstation with a 4K surgical display on a compact, stable cart
Ergonomic layout of ports and sensors with sterile covers
Clean cable management and secure hospital network connectivity
Quick access to I/O and compliant, secure image storage
The result is a solution that started as research, was productized by Bita Negar Afzar as robust software, and was engineered on a purpose-built trolley for the OR—faster, more precise, and cost-effective, ready to support critical surgical decisions.
