New Ultrasound Method Could Increase Understanding of Cancer Cells and Metastases

The lateral movement of the cells enables the researchers to identify their acoustic properties, and could be used to detect the cell type, and distinguish between cancer cells of different origins.

The study was published in the May 2016, issue of the online journal Nature Communications. The method could be used to measure the variation in the number of tumor cells in time and help determine whether medication can be effective in treatment or not.

Per Augustsson, Department of Biomedical Engineering, Lund University, said, “The vision is that our innovation will eventually be used in healthcare facilities, for example, to count and distinguish different types of cells in patients’ blood. It may seem odd that we are interested in the acoustic properties of blood cells and cancer cells. But we have been searching for new methods to separate cells in order to study them in more detail. Since we are looking for individual cells in a blood sample which contains billions of cells, the smallest overlap in size between the cancer cell and other blood cells will lead to thousands of blood cells ‘contaminating’ the cancer cells extracted through the separation. This is why we have now developed iso-acoustic focusing.”
