Researchers have developed a new method to improve 3D spatial reasoning in medical multimodal large language models (MLLMs). This approach addresses the challenges of high annotation costs and data opacity in 3D medical imaging by creating a large-scale structured reasoning dataset through a novel slice-wise data synthesis paradigm. The synthesized data models the diagnostic workflow of radiologists, decomposing the 3D reading process into fine-grained, per-slice observations that form an interpretable Chain-of-Thought. Instruction-tuning a 2D-pretrained MLLM with this data significantly enhances its volumetric comprehension and spatial reasoning capabilities, rivaling native 3D architectures without requiring 3D-specific pre-training.
