Development of the template prostate biopsy method with the three-dimensional space position recognition system

我们将市售的前列腺癌种子植入软件的基本系统应用于常规的经会阴模板活检，并建立了标准程序来显示样本核心的位置以及在前列腺的3D映射中区分癌症和非癌症核心。此外，我们还建立了叠加识别系统，从所获得的岩心三维映射中调查冷区。结果表明，从样本病例来看，冷区可能位于背部和尿道周围。对从3D映射计算的预测癌症体积与接受根治性直肠癌切除术的病理癌症体积之间进行统计分析，并且观察到高度相关性。

We applied the basic system of commercially available prostate cancer seed implant software to the conventional transperineal template biopsy, and established the standard procedure to show the location of sample core as well as the distinction of cancer and non-cancer cores in the 3D mapping of the prostate. Also, we established the superposition recognition system to investigate the cold area from the obtained 3D mapping of the cores. In results, from the sample cases, cold area was likely to locate in the dorsal portion and around urethra. Statistical analysis between predicted cancer volume calculated from 3D mapping and pathological cancer volume undergoing radical prostatectomy was conducted, and high correlation was observed.
