Data underlying the publication: Overcoming pubic arch interference in prostate brachytherapy using steerable needles

Data includes DICOM files of prostates and the analysis of the data underlying the publication: Overcoming pubic arch interference in prostate brachytherapy using steerable needles.<br>Geometrical analyses were performed on datasets of 27 patients who had undergone a diagnostic MRI scan and of which the anatomy was segmented by an approved clinician. Objective of this research was to evaluate if the current clinical guidelines related to prostate volume and prostate accessibility are sufficient, and to define the requirement for needle steering for the avoidance of pubic arch interference.<br>The data was collected from the database of the Portsmouth Hospital University NHS Trust and the patient’s eligibility criteria for this study included clinical stage T1-T3b cancer, a Gleason score of ≥ 3+3, any serum <em>prostate-specific antigen</em> (PSA), and an original V_p of ≥ 60 cc based on the formula: V_p = π/6 × (height × width × length).<br>

本数据集包含前列腺的DICOM影像文件，以及支撑论文《使用可操纵针解决前列腺近距离放射治疗中的耻骨弓干扰问题》的数据分析内容。
本研究针对27名患者的数据集开展了几何分析：这些患者均接受过诊断性磁共振成像（Magnetic Resonance Imaging, MRI）扫描，其解剖结构已由资质认证的临床医师完成分割。本研究旨在评估当前针对前列腺体积与前列腺可及性的临床指南是否足够完备，并明确为规避耻骨弓干扰所需的针管操纵技术要求。
本数据集采集自朴茨茅斯大学国民保健信托基金会（Portsmouth Hospital University NHS Trust）的数据库，本研究纳入患者的入组标准包括：临床分期为T1-T3b的前列腺癌、格里森评分≥3+3、任意血清前列腺特异性抗原（prostate-specific antigen, PSA）水平，以及基于公式Vₚ = π/6 ×（高度×宽度×长度）计算得到的初始前列腺体积Vₚ ≥60 cc。
