In this work, we present the development of a compact, wireless imaging probe using a cost effective camera based optical elastography technique, stereoscopic optical palpation, towards intraoperative tumour assessment for breast cancer surgery. We demonstrate the working principle of this probe and test its capability of tumour margin assessment on freshly excised tissues. With further development, this probe holds the potential to be used as a real time cancer imaging tool that can help surgeons more effectively remove cancer during the operation, reducing the need for follow-up surgery. The probe has the potential to be used in rural and remote areas.
Assessing mechanical properties of tissue plays an important role in disease diagnosis and clinical examination. Here, we present a low resource and cost-effective method of using digital camera technologies to map mechanical properties of tissue, termed camera-based optical palpation. We applied this technique to breast cancer detection and burn scar assessment, validating its capability of generating high mechanical contrast between various tissue regions for clinical applications. We also implemented camera-based optical palpation in a smartphone, demonstrating its potential for telehealth applications in rural and remote areas, improving equity of access to optimal treatment for people all around the world.
