The imager is positioned at a distance of approximately 70 cm from the subject who is seated upright throughout the examination. This position will be maintained throughout the imaging session. An initial period of temperature equilibrium precede the imaging process, during which the patient sits in the dedicated imaging room with room temperature set at 18-22 degrees Celsius. Following the temperature equilibration phase, continuous infrared imaging will be acquired for a period of up to 7 minutes. Two minutes after beginning of infrared recording, a metabolic stress test will be induced by having the patient wear cold gloves (0-5 degrees Celsius), which will be removed after 1 minute. This is performed for the purpose of generating vasoconstriction in the breast vessels. The entire imaging session will last approximately 22 minutes. The procedure is comfortable, non-invasive and does not emit or involves any ionizing radiation.
