SDTB dataset

The proposed SDTB dataset is collected from microscopic testicular tissue sections of 15 patients diagnosed with azoospermia. It simulates the process of selecting high-quality sperm in a testicular puncture scenario for further infertility diagnosis and treatment. Specifically, a testicular puncture is performed on these patients, followed by cleansing and shredding of the tubule tissue. The samples are then examined under a Nikon ECLIPSS Ti microscope at 200× magnification. The annotations of sperm are initially conducted by one physician and subsequently reviewed and adjusted by another physician. From each patient, 45 to 148 images with 193 to 755 sperm instances are collected. Each image is 1320 × 1080 pixels, which we further resize and pad to 640 × 640 pixels. 

本研究提出的SDTB数据集采集自15例确诊为无精子症（azoospermia）的患者的睾丸显微组织切片。该数据集模拟睾丸穿刺（testicular puncture）场景下优质精子的筛选流程，用于辅助不孕症的后续诊断与治疗。具体而言，研究人员先对上述患者实施睾丸穿刺术，随后对曲细精管组织进行清洗与解离。将制备好的样本置于尼康ECLIPSS Ti显微镜下，以200倍放大倍率进行成像。精子标注工作首先由一名医师完成，随后由另一名医师复核并调整标注结果。每位患者对应采集45至148张图像，单张图像包含193至755个精子实例。原始图像分辨率为1320×1080像素，后续我们将其统一调整尺寸并填充至640×640像素。

背景与挑战

背景概述

SDTB数据集是一个专注于精子检测的医学图像数据集，包含15名无精症患者的显微睾丸组织切片图像，图像分辨率高且精子实例尺寸小，检测任务具有挑战性。数据集已分为训练、验证和测试集，适用于不孕症诊断和治疗研究。
