InferCT: An Efficient and Generalizable Framework to Enable 3D Machine Learning for Computed Tomography
Unlock High-Performance 3D Deep Learning for Massive CT Datasets
inferCT offers a groundbreaking framework designed to overcome the computational and memory limitations of 3D deep learning inference on large-scale Computed Tomography (CT) data. By intelligently partitioning volumes, optimizing data pipelines, and leveraging multi-GPU systems, inferCT delivers significant speedups and scalability, making advanced 3D analysis practical for real-world applications across materials science, medical research, and more.
Executive Impact & Key Performance Metrics
inferCT revolutionizes 3D deep learning for CT by making it feasible for production environments. Our framework drastically reduces inference time and computational overhead, enabling faster analysis of terabyte-scale datasets while ensuring high model accuracy. This translates to accelerated research cycles, more efficient diagnostic workflows, and significant cost savings in GPU resource utilization.

Generalizability & Use Cases
Pipelined Execution & Lock-Free Memory
inferCT employs a novel pipelined execution model that overlaps data prefetching, GPU computation, and data storing across batches. This strategy effectively hides I/O and memory latency, demonstrating up to 96.2% of data prefetching and 92.9% of data storing time hidden. Coupled with a vendor-agnostic parallel data loader and a lock-free shared memory structure, synchronization overheads are drastically reduced, enabling seamless concurrent inference across multiple GPUs without global barriers.
Multi-GPU Data Parallelism
To overcome single-GPU memory limitations, inferCT implements a data parallelism strategy that partitions large CT volumes into smaller sub-volumes, distributing them across multiple GPUs. This approach achieved strong scaling efficiencies of 89.25% for 1-4 GPUs within a single NUMA node and 75.75% for 1-8 GPUs across two NUMA nodes on a 4096³ dataset. This robust scalability paves the way for processing terabyte-scale CT data on distributed clusters.
Vendor-Agnostic & Task-Independent
The inferCT framework is designed to be independent of dataset size, imaging task, and GPU architecture. While demonstrated with CT image denoising using U-Net on synthetic datasets up to 4096³ voxels, its architectural flexibility allows application to any CNN-based deep learning model. Future work will extend its utility to other critical 3D imaging tasks like semantic segmentation and registration, validating its performance on large-scale, real-world datasets.
