As imaging volumes explode, your CPU-bound pipelines will eventually start to choke on 3D studies, slowing diagnostics and innovation. Medical image processing with L40S is redefining how HealthTech startups handle CT, MRI and X-ray workloads. For example, cutting end-to-end inference latency and increasing throughput so teams can run larger 3D segmentation/reconstruction models on higher-resolution studies without slowing clinical pipelines.
Built on NVIDIA’s Ada Lovelace architecture, the L40S GPU brings massive parallel compute, 48 GB of ECC GDDR6 memory (~864 GB/s bandwidth) and 4th-generation Tensor Cores that accelerate segmentation, triage and diagnostic-support workloads.
Startups can rent L40S instances from GPU-first clouds, integrate them to DICOM and PACS data and scale from proof-of-concept to production without owning hardware.
According to a European Society of Radiology (ESR) survey, 47.9% of radiologists already use AI systems in clinical practice and another 25.3% plan to adopt them. So, expectations for fast, AI-ready infrastructure are only rising.
What is the NVIDIA L40S GPU?
The NVIDIA L40S is a versatile, multi-purpose data center GPU built on the Ada Lovelace architecture, designed to accelerate AI, graphics/visualization and HPC workloads on the same infrastructure.
It is designed for AI training and inference (including many large language and vision models), high-performance computing, advanced 3D graphics & rendering and video pipelines that need consistent throughput.

In addition, it includes 4th generation Tensor Cores, 3rd generation RT Cores and 48 GB of memory, which helps you run larger models, process higher resolution data and support 24/7 enterprise reliability in production environments.
How L40S Helps HealthTech Startups in Medical Image Processing
L40S offers several benefits to health-tech startups in medical image processing. Some of the top ones are the following:
1. Improve image analysis with AI
The L40S uses fourth generation Tensor Cores and its Transformer Engine to train and run deep learning models for medical imaging efficiently. You can build models that assist with disease detection, structure segmentation and anomaly identification in MRI, CT and X-ray scans, often reducing time to result and improving consistency compared to purely manual workflows.
Any such models still need rigorous clinical validation and regulatory approval before routine clinical use.
2. Faster image reconstruction
Medical imaging requires heavy computation to turn raw scanner data into high resolution diagnostic images. With the L40S, you can significantly accelerate this reconstruction and post-processing step, reducing the time from scan acquisition to reconstructed, AI-processed images from minutes or hours down to seconds in suitable workflows.
The scanner acquisition time itself remains constrained by modality hardware and protocols.
3. Enhanced visualization and 3D rendering
Using third-generation RT Cores for ray tracing, the L40S delivers high-quality, real-time 3D rendering of volumetric datasets. You can support surgical planning, medical education using VR & AR and advanced scientific visualization with interactive performance instead of offline rendering queues.
4. Cost effectiveness and accessibility
The L40S provides high end performance at a more accessible price for many inference and mixed workloads than flagship GPUs such as the H100 or H200. As a result, you can bring advanced AI capabilities to a broader range of hospitals, imaging centers, research institutions and cloud-based providers.
5. Scalability and flexibility
It is designed for data center use and supports NVIDIA vGPU-based GPU virtualization, letting multiple users or virtual machines share one GPU efficiently.
Note that L40S does not support MIG partitioning; multi-tenant isolation is handled through vGPU profiles and scheduler policies.
You can start with small pilots and scale up to large multi-tenant, cloud-based diagnostic platforms without redesigning your infrastructure.
6. Ecosystem support
It integrates with key medical AI ecosystems including the open-source MONAI framework and the NVIDIA Clara platform. You can use their pre-trained models, reference workflows and deployment tools to shorten the path from experimentation to clinical grade AI applications.
How a Medical Imaging Pipeline on L40S Looks
To actually deliver value in hospitals with L40S, GPU imaging startups need more than raw GPU compute. You need an end-to-end, production-ready pipeline that takes studies from PACS all the way back to the radiologist’s viewer.
In practice, that pipeline goes through a few key stages:
Stage 1: Ingest DICOM from PACS or VNA
Securely pull CT, MRI and X-ray studies from hospital PACS or vendor-neutral archives into a HIPAA-ready VPC. Store them in encrypted block or object storage.
Stage 2: De-identify and govern data
Strip patient identifiers for model development using DICOM de-identification profiles, and keep a re-identification mapping service on the hospital side (inside their network) when results must be linked back to a patient. Apply access controls and audit logging from day one.
Stage 3: Preprocess on the GPU with MONAI
Decode DICOM, resample to common voxel spacing and normalize intensities. MONAI provides GPU-accelerated transforms (alongside CPU ones), so you can push most heavy resampling and augmentation steps onto the L40S and keep data prep scaling with your GPU workload
Stage 4: Train models on L40S
Use mixed precision (FP16/BF16) to tap Tensor Cores and fit 2D/3D or multimodal networks into the 48 GB VRAM. For larger datasets or experiments, scale to multiple L40S GPUs using Distributed Data Parallel (DDP) over PCIe and high-speed Ethernet/InfiniBand – L40S is a PCIe-only card with no NVLink, so interconnect design and batch sizing matter for good scaling.
Stage 5: Optimize inference with TensorRT and serve via Triton
Export models to TensorRT for low-latency inference and host them on NVIDIA Triton or your inference stack so you can batch requests and monitor latency and throughput.
Stage 6: Integrate results back into PACS and viewers
Wrap inference behind DICOM-aware services that send overlays, measurements or structured reports back into the radiologist’s existing tools.
If you’re running multi-tenant or multi-environment setups, you can separate training and inference into different Kubernetes clusters on AceCloud, for example one cluster for model training and experimentation and another for production inference, with dedicated namespaces per customer or environment.
What are the NVIDIA L40S Use Cases?
Here are practical NVIDIA L40S use cases that show real clinical impact across imaging workflows:
CT and MRI triage
CT and MRI triage models on L40S focus on one thing: getting the right patient seen first. Deep learning systems can scan incoming neuro, chest or trauma studies in near-real time and flag suspected stroke, hemorrhage or pulmonary embolism for prioritized review, once clinically validated and integrated into the workflow.
Running these models on L40S keeps inference latency low even at peak load so critical cases move to the top of the radiologist worklist instead of waiting behind routine exams.
Segmentation for planning and follow-up
Segmentation models often use 3D UNet style architectures that need a lot of GPU memory and compute. On L40S, these networks contour tumors, organs at risk and other structures directly from volumetric CT or MRI.
This speeds radiotherapy planning, surgical preparation and long term follow up. Clinicians get consistent segmentations while engineers gain room to test larger more expressive models.
Pathology and ophthalmology imaging
Digital pathology and ophthalmology both work with very high-resolution images such as whole slide scans and detailed fundus or OCT images. The 48 GB of VRAM on L40S supports dense tiling, larger batches and deeper networks, significantly reducing memory pressure for whole-slide and high-resolution inputs.
You’ll still typically use tile- or patch-based training and inference for full whole-slide images, but you can push more tiles and richer models per GPU than with smaller cards. Tensor Cores accelerate training and inference for detection and segmentation so AI can assist with grading, lesion detection and region proposals inside existing diagnostic tools.
Ultrasound and endoscopy video
Ultrasound and endoscopy produce continuous video rather than single images which puts more pressure on latency. When you pair local edge platforms such as Clara Holoscan for ultra-low-latency overlays with L40S clusters in the cloud for heavier training and batch analytics, you can deliver real-time AI guidance (tool tracking, polyp highlighting, image quality feedback) at the edge while using cloud GPUs for offline learning, quality review and dataset curation.
Recorded streams run later on L40S for offline learning, quality review, and dataset curation.
Multi-modal imaging + EHR fusion
Many valuable use cases need more than pixels alone. With L40S teams can run models that combine DICOM images with structured EHR fields, lab values and even report text. These multimodal architectures predict risk, suggest next tests or stratify patients for follow up.
The GPU memory and Tensor Core performance make it practical to train and serve these richer models without losing responsiveness.
