Researchers have developed CT-3GDINO, a novel 3D object detection model designed for organ localization in abdominal CT scans. This lightweight model adapts a Grounding-DINO-style architecture, utilizing frozen pseudo-text class tokens instead of a traditional text encoder. CT-3GDINO integrates a Swin3D backbone, bidirectional feature enhancement, and a cross-modality decoder to predict bounding boxes for organs like the liver, spleen, and kidneys. Evaluated on 193 CT volumes, the model achieved a competitive mAP score, demonstrating strong performance for coarse localization while identifying areas for improvement in precise box alignment. AI
