A clinical prototype for active microwave imaging of the breast

Recent Advances in Microwave Imaging for Breast Cancer Detection

“…Microwave tomography has been studied by several research groups [18–20, 62–85]. Prof. Paulsen and Prof. Meaney from Dartmouth College in the United States are one of the representative research groups.…”

“…The Dartmouth group has developed a clinical prototype for active microwave imaging of the breast for the first time [18]. They developed a 32-channel data acquisition system operating at frequency range 500 MHz to 3 GHz [87] to obtain data from a clinical prototype exam.…”

Thermoacoustic imaging over large field of view for three‐dimensional breast tumor localization: A phantom study

“…5,6 Thermoacoustic (TA) signals carry the microwave absorption properties of the target, thus local microwave absorption can be mapped by processing the collected TA signal from the scanned target area using limited-field-filtered backprojection algorithms. [7][8][9] It is well-known that a significant difference exists in the dielectric character between normal and malignant breast tissues.…”

A Multi-Scaling Forward-Backward Time-Stepping Method for microwave imaging

“…The development of reliable procedures for the solution of electromagnetic inverse scattering problems has received a growing attention in the last years due to their occurrence in NDE=NDT [1,2,3], biomedical diagnostics [4,5,6,7,8,9,10,11], and geophysical applications [12]. Nevertheless, generalpurpose and efficient inversion methodologies are often not available because of the intrinsic drawbacks of the problems at hand, namely the ill-posedness and strong non-linearity [13].…”
