Philips is developing an ultrasound-based drug delivery technology that is designed to increase the effectiveness and reduce the side effects of chemotherapy treatment for certain types of cancer. The system proposes the use of drug-loaded microbubbles, no larger than red blood cells, that can be injected into the patient's bloodstream, tracked via ultrasound imaging, and then ruptured by a focused ultrasound pulse to release their drug payload when they reach the desired spot. Because the drugs would only be released at the site of the diseased tissue, the patient's total body exposure to them could be limited. For certain types of treatment - for example, chemotherapy for breast cancer - this could help to reduce unpleasant side effects.
