# NV-Generate-CT

3D CT Synthesis

Commercial

Generate high-resolution synthetic CT volumes up to 512x512x768 with controllable anatomy and paired segmentation masks.

CT [HuggingFace](https://huggingface.co/nvidia/NV-Generate-CT) [GitHub](https://github.com/NVIDIA-Medtech/NV-Generate-CTMR) [Paper](https://arxiv.org/abs/2508.05772)

### Run it with an agent

Install the skill, then just ask your agent in plain language. `medagent.nv_generate_ct_rflow`

install skill Copy

```bash
npx skills add NVIDIA-Medtech/medical-AI-skills --skill nv-generate-ct-rflow
```

Try saying

“Generate a synthetic abdomen CT and paired segmentation mask from my config at /data/abdomen\_request.json using nv-generate-ct-rflow.”

“Before launching rflow-ct inference, check whether this request is valid and estimate cost.”

“Synthesize a chest CT volume with paired masks from configs/ct\_request.json and summarize the output dimensions.”

“Do a dry-run preflight of my rflow-ct request and tell me the expected GPU memory and runtime before I commit.”

### Finetune it with an agent

Install the skill, then just ask your agent in plain language. `medagent.nv_generate_vae_finetune`

install skill Copy

```bash
npx skills add NVIDIA-Medtech/medical-AI-skills --skill nv-generate-vae-finetune
```

Try saying

“Fine-tune the NV-Generate VAE using CT and MRI images listed in /data/ctmr/vae\_datalist.json.”

“Check whether my VAE finetune datalist is runnable before launching the GPU job.”

“Kick off a smoke-scale MAISI VAE finetune from data/ctmr/vae\_datalist.json and report where checkpoints are written.”

“Validate my CT/MRI VAE datalist and stage the VAE configs before I commit to a full GPU run.”
