To test low-cost phantoms for training in stereotactic breast biopsy, we prepared eggplant with calcium powder; gelatin and turkey breast with coarse salt, peppercorns, and calcium powder, respectively; and short-bread pastry with salt. Three to 12 cores were harvested with an 11-gauge vacuum biopsy unit. Mammography images were taken before and after biopsy and from the biopsy cores. The pastry phantom provided the best simulation of microcalcifications for stereotactic biopsy with realistic cores, long durability, and short preparation time.
为了测试立体定向乳腺活检培训用的低成本模型，我们分别用钙粉、明胶和火鸡肉，以及粗盐、黑胡椒粒和钙粉来制作茄子模型；用盐来制作酥饼模型。使用 11 号活检真空枪采集 3 到 12 个芯。在活检前后以及从活检芯采集乳腺 X 线照片。酥饼模型在真实芯、长耐久性和短准备时间方面为立体定向活检的微钙化模拟提供了最佳效果。
