1 Microwave Near-field Imaging of Human Tissue: Hopes, Challenges, Outlook Natalia K. Nikolova McMaster University, 128 Main Street West, Hamilton, ON L8S 4K1, CANADA Department of Electrical and Computer Engineering

2 Outline microwave imaging emerging modality in medical imaging imaging approaches experimental setups reconstruction approaches recent developments sensors and phantoms data acquisition via aperture scanning real-time reconstruction approaches looking forward WMG: Recent Developments in Microwave Imaging and Detection 2

3 Microwave Imaging Emerging Modality first systematic studies date back to 1978 [Larsen & Jacobi eds. 1986] S 21 scan, 3.9 GHz dissection S 21 co-pol canine kidney scan in water [Jacobi 1978] chirp-radar scan (5 MHz to 2 GHz) S 21 cross-pol 3

4 Microwave Imaging: Conclusions from Early Experiments resolution on the order of a centimeter coupling microwave energy into tissue improved by coupling liquids significant tissue heterogeneity significant tissue dissipation compromise between penetration depth (better at low frequencies) and resolution (better at high frequencies) optimal frequency range: 2 GHz to 8 GHz [Lin 25],.5 GHz to 3 GHz [Li 24, Semenov 25] microwaves hold promise for early-stage breast cancer diagnostics [Sepponen 1987] WMG: Recent Developments in Microwave Imaging and Detection 4

5 Microwave Imaging: Some Facts about Breast Cancer the 2 nd largest cause of female cancer deaths in the US; annually: over 2, diagnosed, about 4, dying; incidence among women: 1 in 8 [ACS 21] early-stage (below 1.5 cm) detection is crucial (> 9% survival rate) current modalities are not satisfactory mammography: the standard, high false-negative rate (~15%), ionizing, discomfort due to compression MRI: not suitable for mass screening, high false-positive rate, contrast agent required ultrasound: low specificity, operator dependent [ WMG: Recent Developments in Microwave Imaging and Detection 5

6 Advantages of Microwave Imaging advantages of microwave technology in cancer diagnostics safe: non-ionizing and very low SAR (frequent check-ups) no need for significant breast compression relatively cheap compact technology (deployment in GP offices) other applications of near-field microwave imaging security surveillance (concealed weapon detection) underground surveillance nondestructive testing and evaluation WMG: Recent Developments in Microwave Imaging and Detection 6

7 Tissue Constitutive Parameters breast tissue constitutive parameters [Lazebnik 27, Halter 29] 5 major tissue types: skin, muscle, adipose (fat), fibroglandular (FG), cancerous (benign, malignant) adipose tissue features the lowest ε r and σ (ε r 4 to 6 and σ.2 3 GHz) while tumors feature the highest values (ε r 44 to 59 and σ 2.5 to 3 3 GHz) contrast between FG tissue and tumors is small ( 1% in ε r, up to 1% in σ, still under investigation); FG tissue is the place where most cancers appear [Lazebnik 27, Poplack 27, Halter 29] significant frequency dispersion WMG: Recent Developments in Microwave Imaging and Detection 7

8 Tissue Constitutive Parameters Ongoing Studies more on the contrast between healthy FG tissue and tumors previous studies ex vivo, small-scale, inconsistent protocols for tissue acquisition, many discrepancies, claim high contrast (factors of 5 to 1) between normal breast tissue and malignant tissue two major recent studies ex vivo U of Wisconsin-Madison & U of Calgary [Lazebnik 27] very low mean contrast: in ε r about 8%, in σ about 1% in vivo Dartmouth College [Poplack 27, Halter 29] contrasts are higher in vivo ε r and σ decrease after excision more in vivo studies necessary WMG: Recent Developments in Microwave Imaging and Detection 8

12 Experimental Setups: Coupling Liquids tanks of coupling liquids typically used to improve energy coupling into tissue Dartmouth C [Meaney 2] U of Manitoba [Zakaria 21] U of Calgary [Sill 25] 12

13 Liquid-free Experimental Setups recent trend toward liquid-free setups (gels may be used instead) easy maintenance no danger of contamination contact with tissue through thin layers of protective coating & gel challenging sensor design Duke U [Stang 29] U of Bristol [Research Review, Winter 29 online publicity material] WMG: Recent Developments in Microwave Imaging and Detection 13

14 Outlook: Imaging Algorithms and Software microwave holography sensitivity-based reconstruction confocal multistaticreconstruction diffraction tomography EM models and gradient-based nonlinear inversion real-time performance 14

15 Outlook: Hardware and Measurements improving sensors miniaturization crucial in array configurations improving scanning apparatus co- and cross-pol interrogation crucial for specificity time-domain interrogations chirp waveforms vs. pulsed radar pulse shaping in vivo measurements of healthy and malignant breast tissues contrast agents for microwave imaging 15
