In mild hyperthermia (MHTh), targeted tumors are heated to approximately 41 to 44°C, typically to enhance chemo-, radiation, and/or immunotherapy. This study demonstrates the efficacy of a ring-array ultrasound (US) transducer in generating and monitoring MHTh in heterogeneous media. A ring-array provides enhanced focusing and heat localization compared to conventional linear-array US. We simulated scenarios using either one, two, or four 128-element linear-array transducers, or a 256-element ring-array transducer, to generate focused US profiles. The full width half maximum (FWHM) was measured to quantify the results. The ring-array achieved the most accurate and localized focal pressure profile with a focal spot size of 2×2mm. In a simulated heterogeneous breast model, sound speed (SS) compensation with a ring-array resulted in more efficient acoustic focusing than non-compensated fields. The focal point without SS compensation shifted spatially from its target due to acoustic aberrations, highlighting the importance of aberration correction for precise heat localization. Additionally, the ring-array's heat generation capability was evaluated in-vitro using a tissue-mimicking phantom, where the temperature at the focal point was increased by 6°C in 12 minutes and was sustainable. Lastly, the capability of a ring-array to track temperature was evaluated using US tomography (UST) in another in-vitro experiment. Here, a cylindrical inclusion in a tissue-mimicking phantom was filled with preheated water and allowed to passively cool from 45°C to 25°C. A ring-array tracked the temperature changes based on SS images with a mean error of 0.06±0.28°C. In summary, a ring-array transducer (1) achieved the best focal profile compared to standard linear transducers, (2) accomplished superior aberration correction using SS images, resulting in better aberration-free focusing in heterogeneous media, (3) generated sustainable heat at a focal point, and (4) accurately monitored temperature changes with UST.

Ultrasound tomography (UST) employs sound waves to produce three-dimensional images of breast tissue and precisely measures the attenuation of sound speed secondary to breast tissue composition. High breast density is a strong breast cancer risk factor and sound speed is directly proportional to breast density. UST provides a quantitative measure of breast density based on three-dimensional imaging without compression, thereby overcoming the shortcomings of many other imaging modalities. The quantitative nature of the UST breast density measures are tied to an external standard, so sound speed measurement in breast tissue should be independent of specific hardware. The work presented here compares breast sound speed measurement obtained with two different UST devices. The Computerized Ultrasound Risk Evaluation (CURE) system located at the Karmanos Cancer Institute in Detroit, Michigan was recently replaced with the SoftVue ultrasound tomographic device. Ongoing clinical trials have used images generated from both sets of hardware, so maintaining consistency in sound speed measurements is important. During an overlap period when both systems were in the same exam room, a total of 12 patients had one or both of their breasts imaged on both systems on the same day. There were 22 sound speed scans analyzed from each system and the average breast sound speeds were compared. Images were either reconstructed using saved raw data (for both CURE and SoftVue) or were created during the image acquisition (saved in DICOM format for SoftVue scans only). The sound speed measurements from each system were strongly and positively correlated with each other. The average difference in sound speed between the two sets of data was on the order of 1-2 m/s and this result was not statistically significant. The only sets of images that showed a statistical difference were the DICOM images created during the SoftVue scan compared to the SoftVue images reconstructed from the raw data. However, the discrepancy between the sound speed values could be easily handled by uniformly increasing the DICOM sound speed by approximately 0.5 m/s. These results suggest that there is no fundamental difference in sound speed measurement for the two systems and support combining data generated with these instruments in future studies.

Conventional sonography, which performs well in dense breast tissue and is comfortable and radiation-free, is not practical for screening because of its operator dependence and the time needed to scan the whole breast. While magnetic resonance imaging (MRI) can significantly improve on these limitations, it is also not practical because it has long been prohibitively expensive for routine use. There is therefore a need for an alternative breast imaging method that obviates the constraints of these standard imaging modalities. The lack of such an alternative is a barrier to dramatically impacting mortality (about 45,000 women in the US per year) and morbidity from breast cancer because, currently, there is a trade-off between the cost effectiveness of mammography and sonography on the one hand and the imaging accuracy of MRI on the other. This paper presents a progress report on our long term goal to eliminate this trade-off and thereby improve breast cancer survival rates and decrease unnecessary biopsies through the introduction of safe, cost-effective, operatorindependent sonography that can rival MRI in accuracy. The objective of the study described in this paper was to design and build an improved ultrasound tomography (UST) scanner in support of our goals. To that end, we report on a design that builds on our current research prototype. The design of the new scanner is based on a comparison of the capabilities of our existing prototype and the performance needed for clinical efficacy. The performance gap was quantified by using clinical studies to establish the baseline performance of the research prototype, and using known MRI capabilities to establish the required performance. Simulation software was used to determine the basic operating characteristics of an improved scanner that would provide the necessary performance. Design elements focused on transducer geometry, which in turn drove the data acquisition system and the image reconstruction engine specifications. The feasibility of UST established by our earlier work and that of other groups, forms the rationale for developing a UST system that has the potential to become a practical, low-cost device for breast cancer screening and diagnosis.
