These studies covered multiple imaging modalities, with most using synthetic DRR datasets derived from CT and others extending to coronary angiography and MRI applications. Architectures varied: MedNeRF and UMedNeRF retained baseline GNeRF backbones, while RepMedGraf, ACNeRF, and imp\u2010MedNeRF introduced adversarial or pose\u2010aware techniques. Metrics such as PSNR, SSIM, and FID were used to benchmark performance. However, all studies relied on small or synthetic datasets, limiting\u00a0generalizability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Reviewed studies indicate that GNeRF methods show early promise in reducing radiation dose in ionizing imaging modalities (e.g., CT, x\u2010ray) and in reconstructing anatomy from sparse views; however, translation to clinical workflows is not yet feasible.
