A low intensity (ISPTA < 5 W/cm2) pulsed ultrasound (LIPSA) approach can exploit the mechanical properties of neoplastic cells to target them for destruction. Ultrasound applied at a frequency of 0.5–0.67 MHz for >20 ms causes selective disruption of a panel of breast, colon, and leukemia cancer cell models in suspension without significantly damaging healthy immune or red blood cells.
A meta-analysis found that ultrasound therapy is effective in reducing pain, increasing ROM, and reducing WOMAC functional scores in patients with knee osteoarthritis. [7] There are three potential therapeutic mechanisms of ultrasound in physical therapy. The first is the increase in blood flow in the treated area.
Sonodynamic therapy could be used to treat cancers and other diseases, such as atherosclerosis, and diminish the risk associated with other treatment strategies since it induces cytotoxic effects only when externally stimulated by ultrasound and only at the cancerous region, as opposed to the systemic administration of chemotherapy drugs.
Radio frequencies at non-ablation energy levels are commonly used as a part of aesthetic treatments that can tighten skin, reduce fat by lipolysis and also apoptosis, [4] or promote healing. [5] RF diathermy is a medical treatment that uses RF induced heat as a form of physical therapy and in surgical procedures. It is commonly used for muscle ...
Alternatively, if gravitons are massive at all, the analysis of gravitational waves yielded a new upper bound on the mass of gravitons. The graviton's Compton wavelength is at least 1.6 × 10 16 m , or about 1.6 light-years , corresponding to a graviton mass of no more than 7.7 × 10 −23 eV / c 2 . [ 18 ]
The Network expects the new machines to cut waiting times, provide better care and allow new forms of treatment. More: UVM Cancer Center bringing innovative cell-based treatment to Vermont: Who it ...
Other radiation therapy machines which incorporate real-time MRI tracking of tumors are currently in development. MRI-guided radiation therapy enables clinicians to see a patient's internal anatomy in real-time using continual soft-tissue imaging and allows them to keep the radiation beams on target when the tumour moves during treatment.

Photosensitizers, already in clinical use for photodynamic therapy, can be detected using MSOT, allowing analysis of their pharmacokinetics and bio-distribution in vivo. [51] Light-absorbing nanoparticles offer potential advantages over organic dyes because of their ability to produce stronger photoechoes and their lower photosensitivity. One ...
