[Abstract]:Positive photoacoustic imaging does not require biopsies and smears. The principle of the technique is that cancer tissue can absorb more light, because cancer tissues such as new abnormal angiogenesis and less collagen fibers. Ultrasound scans can detect cancer tissue because the cancer cells absorb more light to produce heat, causing cells to expand and affect the sound waves of the rebound scanner, resulting in image changes. The researchers say photoacoustic imaging can also identify stages of cancer. Because the higher the cancer progresses, the more light the cancer absorbs, and the more echoes are displayed in ultrasound scans. The technique has been tested in clinical trials, with 30 women with cancer as well as healthy women.
