# Pulmonary DPM-Solver in Imaging Workflows

Searching arXiv for the cited DPM-Solver papers to ground the article in the current literature.
The expression “Pulmonary DPM-solver” is best understood as the use of the DPM-Solver family of fast diffusion ordinary differential equation samplers within pulmonary imaging workflows, rather than as the name of a pulmonary-specific algorithm. In the underlying literature, DPM-Solver is a training-free, dedicated high-order solver for diffusion probabilistic model sampling in around \(10\sim 20\) function evaluations, and DPM-Solver-v3 extends this line by choosing the sampling parameterization from empirical model statistics computed on a pretrained model rather than fixing it to noise prediction or data prediction [2206.00927][2310.13268]. The pulmonary qualifier therefore denotes a prospective deployment context—such as pulmonary CT reconstruction, lung image synthesis, or chest-image augmentation—while the cited works themselves contain no pulmonary, thoracic, radiology, or medical imaging experiments.

## 1. Definition and scope

Within diffusion-model sampling, DPM-Solver and DPM-Solver-v3 address the computational bottleneck created by the need for repeated neural-network evaluations along a denoising trajectory. The original DPM-Solver paper frames sampling as solving the corresponding diffusion ODE and proposes a fast dedicated solver that analytically computes the linear part of the solution rather than treating the entire vector field with a black-box numerical integrator [2206.00927]. DPM-Solver-v3 revisits a different but closely related question: what model parameterization should actually be approximated during numerical integration, and can that choice be estimated from the pretrained model itself [2310.13268].

This scope matters for pulmonary usage because the same sampling bottleneck arises whenever each function evaluation is expensive. The DPM-Solver-v3 paper explicitly notes that this is particularly painful in text-to-image systems and would be equally relevant in any medical imaging diffusion pipeline—such as pulmonary CT reconstruction or lung image synthesis—where 3D or high-resolution models are even more expensive per step [2310.13268]. At the same time, the paper also states that it does not contain pulmonary, thoracic, radiology, or medical imaging experiments. A plausible implication is that “Pulmonary DPM-solver” refers not to a validated medical method, but to a general fast diffusion ODE sampler that could be transplanted into pulmonary image generation or reconstruction pipelines.
