Imaging properties of 3D printed breast phantoms for lesion localization and Core needle biopsy training
Abstract Background Breast cancer is the most commonly diagnosed malignancy in females and frequently requires core needle biopsy (CNB) to guide management. Adequate training resources for CNB suffer tremendous limitations in reusability, accurate simulation of breast tissue, and cost. The relativel...
