All auxiliary equipment, including a power supply and a laser, is placed in a backpack, the weight of which does not exceed 7 kilograms. The latter is designed so that a person can move freely with it, while ensuring the stability of the system, reports Techcult.ru.

Using this technique, it is possible to scan tissues to a depth of up to 30 millimeters. This is optimally suited for assessing the condition of blood vessels and the level of oxygen saturation in the blood. The author of the study, Lei Xi, points out that this is the world's first photoacoustic device suitable for practical use in medicine. By analyzing heart rate, blood pressure and blood oxygenation levels, it is possible to determine with high accuracy how well a person's heart is working.

The described device has already been tested on several volunteers who have tested it in various conditions. Testing has confirmed the overall convenience of the system and a high level of stability. In the future, the device can be improved, and its dimensions reduced down to miniature ones.

Scientists are confident that the backpack can be discarded by placing all the necessary components in the case of a smart watch. The device can be used not only to assess the condition of blood vessels, but also to diagnose cancer and diseases of the cardiovascular system in the early stages.
