Image guided superficial radiation therapy (IGSRT) is a novel technology which combines traditional superficial radiation therapy (SRT) with high resolution dermal ultrasound (HRDUS) to treat non-melanoma skin cancers (NMSC). Since development, IGSRT use has expanded dramatically in outpatient clinics...
A device that uses high frequency electromagnetic waves to accelerate charged particles such as electrons to high energies through a linear tube. The high-energy electron beam itself can be used for treating superficial tumours or it can be made to strike a target to produce high-energy (MV) ...
Additionally, the risk of thermal burn to the skin limits the treatment of superficial lesions.

Despite its tremendous potential, application of conventional PDT has been restricted as adjuvant therapy and to only superficial tumors due to its inability to treat deep-seated tumors attributed to: poor penetration depth of visible light in tissues, inefficient accumulation of PS ...
The HDR brachytherapy plans were superior to 50 kV superficial photon plans for IORT in all dosimetric parameters except for the heart and rib dosimetric parameters. Prescription dose of 12.5 Gy to the planning target volume for evaluation yielded a dose to 95 percent of the balloon surface of ...
(i.e., a high penetration depth), X-ray and MRI are the optimal modalities, followed by radiotracer-based detection, ultrasound, and then optical tracers. Thus, the applications of optical imaging are still limited to superficial examinations, where the effects of light attenuation from both ...
it is always used for superficial tumors and is combined with drug treatments.27,28 On the basis of these studies, we loaded IR780 into liposomes modified by FA (FA-IR780-NP) and applied it to ovarian cancer, a malignant tumor with high mortality located deep in the body, to evaluate ...
Due to the poor treatment of these superficial veins, varicose veins reoccur at a rate of 20 to 40 percent22. In particular, the unwanted thermal dose (heat) deposited into the ablated tissue has also been postulated to cause more endovenous heat induced thrombosis (EHIT)23. Currently, ...
For superficial anaesthesia, lidocaine buffered in sodium bicarbonate may be used to reduce the initial stinging sensation of the lidocaine injection [41,58]. In the case of allergy to lidocaine, alternative drugs have to be used. Even with optimal local anaesthesia, some discomfort or pain may ...
Because low-energy X-ray photons have very limited penetrating ability, they deposit their energy in a patient's superficial tissues, exposing these structures without contributing to image formation. Thus, it is desirable to remove (filter) low-energy photons from the X-ray beam. Aluminum has ...
