本文提出了一种利用磁调制氧化铁纳米颗粒增强超宽带乳腺成像对比度的方法。研究的动机是乳腺中恶性和正常腺体/纤维结缔组织之间的低介电对比。在这方面的贡献两种不同的调制方法进行了研究。使用M序列UWB技术和油明胶乳房模型进行测量。结果表明，根据磁场强度和体模大小，磁性纳米颗粒积聚在5 mg至0.5 mg范围内的可检测性。
This paper presents a contrast enhancing approach for Ultra-wideband breast imaging by means of magnetic modulated iron oxide nanoparticles. The investigations are motivated by the low dielectric contrast between malignant and normal glandular/fibroconnective tissues in the breast. In this contribution two different modulation approaches are investigated. Measurements were conducted using M-sequence UWB technology and oil-gelatin breast phantoms. The results show a detectability of magnetic nanoparticles accumulations in the range of 5 mg down to 0.5 mg depending on the magnetic field intensity and the phantom size.
