It is important to consider the person's medical history and any ongoing treatments.\n* Sunburn: Recent sun exposure of the skin may lead to increased sensitivity to laser light and can be more likely to experience discomfort or skin irritation\u002Fdamage. This can both affect the reliability of the study and increase the risk of injury to the research subjects.\n* History of keloid formation or scarring: People who have a history of excessive scarring may be more likely to react with greater skin irritation from the laser light.\n* For breast measurements only: History of breast cancer or surgery.

In addition, invasive tissue samples often need to be taken with biopsy needles to, for example, safely determine or rule out a cancer diagnosis. With this project, the investigators evaluate a light-based (optical) method combined with ultrasound that is completely harmless to humans, ultrasound-optical-tomography (UOT). UOT is predicted to be able to penetrate deeper into the body to measure functions and image tissues than was previously possible with other optical imaging methods.\n\nThe aim of this project is to explore the capabilities and safety of UOT regarding imaging depth and tissue property information in healthy participants, as a first step to understand the technology's capabilities and limitations.\n\nThe long-term goal, in future steps, is to develop the technology for clinical assessment of cancer-suspected lesions with a particular focus on breast cancer and for assessment of circulatory disorders in tissue.",[28,29,30,31],"Healthy Tissue","Muscles","Extremity","Breast",[33,34,35,36,37,38],"Optical Imaging","Tissue Oxygenation","Breast \u002F Breast Neoplasms","Hemoglobin","Photoacoustic Techniques","Healthy Volunteers","RECRUITING","2026-08-06",{"date":42,"type":43},"2026-08-10","ACTUAL",{"date":45,"type":43},"2025-11-25",{"date":47,"type":22},"2027-12",{"name":49,"class":50},"Lund University","OTHER"]
