HeiPorSPECTRAL - the Heidelberg Porcine HyperSPECTRAL Imaging Dataset of 20 Physiological Organs

Hyperspectral Imaging (HSI) is a relatively new medical imaging modality that exploits an area of diagnostic potential formerly untouched. Although exploratory translational and clinical studies exist, no surgical HSI datasets are openly accessible to the general scientific community. To address this bottleneck, this publication releases HeiPorSPECTRAL (https://www.heiporspectral.org), the first annotated high-quality standardized HSI dataset. It comprises 5,758 spectral images acquired with the TIVITA Tissue and annotated with 20 physiological porcine organs in a total number of 11 pigs. Each HSI image features a resolution of 480 x 640 pixels acquired over the 500-1000 nm wavelength range. The acquisition protocol has been designed such that the variability of organ spectra as a function of several parameters including the camera pose and the individual can be assessed. A comprehensive technical validation confirmed both the quality of the raw data and the annotations. We envision potential reuse within this dataset, but also its reuse as baseline data for future research questions outside this dataset, such as the detection of pathologies.高光谱成像（Hyperspectral Imaging, HSI）是一种相对新兴的医学成像模态，其挖掘了此前未被涉足的诊断潜力领域。尽管已有探索性转化医学与临床研究开展，但目前尚无面向全球科学界公开可用的外科高光谱成像数据集。为破解这一研究瓶颈，本研究发布了HeiPorSPECTRAL（https://www.heiporspectral.org）——首个带标注的高质量标准化高光谱成像数据集。该数据集包含由TIVITA Tissue设备采集的5758张光谱图像，所有图像均针对11头猪的20个猪源生理器官完成标注。每张高光谱成像图像的分辨率为480×640像素，采集波长区间覆盖500至1000纳米。本次设计的采集协议可支持评估器官光谱随相机姿态、个体差异等多项参数的变化特性。全面的技术验证已证实了原始数据与标注信息的可靠性与质量。本团队期待该数据集可在本研究框架内得到复用，同时也可作为基准数据集，用于后续超出本研究范畴的各类科研课题，例如病理检测任务。
