Objective assessment of sonographic quality for breast cancer imaging
"The purpose of any medical imaging device is to acquire timely diagnostic information in a manner that poses the lowest cost and risk to patients and society. Ideally, medical imaging systems are designed by maximizing the benefit-to-cost ratio from a set of laboratory measurements that define …

Novel Amino Acid Transporter-Targeted Radiotracers For Breast Cancer Imaging
<p>Breast cancer is the most common malignancy among women in the world. Its 5-year survival rate ranges from 23.4% in patients with stage IV to 98% in stage I disease, highlighting the importance of early detection and diagnosis. <sup>18</sup>F-2-Fluoro-2-deoxy-glucose (<sup>18</sup>F-FDG), using …

Microelectromechanical handheld laser-scanning confocal microscope: application to breast cancer imaging
… indicate that 60% of 6.7 million annual global cancer mortalities and 54% of 10.8 million new patients are in developing nations, unable or unwilling to avail of invasive screening tests that are the current norm. For most cancers, survival rate is strongly dependent on early detection, …

Next generation near infrared (NIR) and shortwave infrared (SWIR) wearables for breast cancer imaging
Neoadjuvant chemotherapy (NAC) is a common breast cancer treatment that involves administering chemotherapy for 3-6 months prior to surgery. This treatment enables more breast-conserving surgeries and even allows for the omission of surgery in some cases. However, about 31% of patients receiving …

A multimodal breast cancer imaging system using coregistered dynamic diffuse optical tomography and digital breast tomosynthesis
… (DOT) is an emerging noninvasive functional imaging method for breast cancer diagnosis and neoadjuvant chemotherapy monitoring. In particular, the multimodal approach of combining DOT with x-ray digital breast tomosynthesis (DBT) is especially synergistic as DBT prior information can be used …

Clinical Translation of Optoacoustic Imaging in Breast Cancer
Optoacoustic (OA) imaging is an emerging low-cost hybrid imaging investigation/technique currently in clinical feasibility studies for breast cancer diagnosis and staging. The technique applies pulsed light to the tissue of interest where molecules absorb the light photons and generate acoustic …

Combined Microwave, Ultrasound and Strain Imaging for Breast Tissue Characterization
Today, breast cancer continues to be one of the most common cancers among women. Early detection of breast cancer can provide patients with the best chance of survival. Imaging methods are routinely used to scan for breast abnormalities, which may include X-Ray mammography, MRI, and ultrasound. The …

Spatial correlation tensor and query-augmented active clustering
… on solving two problems: how to detect the early breast cancer by multimodality imaging data, and how to do guide the machine to auto-label the dataset efficiently. In the first part, we classify multimodal imaging data by incorporating the pixel correlations. Multi-dimensional tensor data has …

Individualized learning and integration for multi-modality data
… tensor learning with an application in medical imaging analysis. In the first part of the thesis, we develop a model-based subgrouping method for longitudinal data. Specifically, we propose an unbiased estimating equation approach for a two-component mixture model with correlated response data. …

Synergistic Combination of Microwaves and Acoustic Signals: Towards Improved Breast Imaging
Microwave-based breast imaging techniques offer the convenience of frequently-repeated scans involving no breast compression, non-ionizing radiation, inexpensive scan costs, sensitivity to water content and low-complexity 3D image reconstruction. These benefits are well-suited for its application …

Mapping the spatial organisation of B cells and immune signalling in TNBC to characterise response to immunotherapy
… of immunotherapy response across multiple cancers. B cells exist in various states of spatial organisation within the tumour microenvironment (TME), which likely support many of their functional roles. However, the landscape of B cell spatial organisation in cancer and specifically in …
