  • Mammograms are often utilized as a supplement to self-breast exams, providing a visualization of any malignancies.
  • mammograms are generated using high-energy radiation, which can be dangerous, and in rare cases, lead to the development of cancer.
  • mammograms are highly prone to human error and/or inconclusive.
  • mammograms show only the shadow of a tumor and fail to reach important areas like lymphatic system near the upper arm/chest region. Thus, detection relies heavily on the interpretation of such shadows by a trained physician. Based on this reliance, physicians have overlooked up to 29 percent of tumors that would have been detected by their peers.

Additionally, such optical techniques may be prone to interference from the size and shape of the patient's body and/or the fluorescence of surrounding tissue, thereby scrambling the processing of optical signals. Addressing the scrambling requires complex analysis, which may introduce errors, including the production of false positives.

Abstract

Dans des modes de réalisation, l'invention concerne des systèmes et des procédés de surveillance sanitaire de routine accessibles et fiables, de détection non invasive et de diagnostic précoce de maladies ou d'états. Dans un mode de réalisation, l'invention concerne un dispositif de surveillance sanitaire comprenant une source de lumière conçue pour émettre des photons dans un guide d'onde optique qui réfléchit ces photons à l'intérieur. Une surface souple peut être comprimée contre le guide d'onde optique pendant le balayage d'un tissu. La compression de la surface souple contre le guide d'onde optique disperse au moins l'un des photons dans le tissu et/ou le renvoie dans le guide optique. Un réseau d'imagerie est conçu pour collecter le/les photon(s) dispersé(s), ce qui forme une image représentant la dureté du tissu par rapport au tissu environnant.
