What is meant by Orthovoltage?

What is meant by Orthovoltage?

Medical Definition of orthovoltage : X-ray voltage of about 150 to 500 kilovolts.

What is superficial radiation?

Superficial radiation delivers radiation therapy using X-rays. The beam only penetrates the surface of the skin. This type of therapy avoids deep tissue damage and minimizes scarring, particularly around the face.

What type of radiation is SRT?

Stereotactic Radiation Therapy (SRT) is a type of external radiation therapy which uses special equipment to precisely position the patient in order to deliver radiation to a well-defined cancerous tumor. With SRT, the total dose of radiation is divided into several smaller doses given over several days.

In what year the Orthovoltage invented?

Since these low energy x-rays were mostly absorbed in the first few centimeters of tissue, to deliver a large enough radiation dose to buried tumors would cause severe skin burns. Therefore beginning in the 1920s “orthovoltage” 200–500 kV x-ray machines were built.

Is superficial radiation safe?

This low-dose of radiation safely destroys cancerous cells without damaging healthy surrounding tissue. Physicians view treatment areas with high-frequency ultrasound allowing them to thoroughly assess and target cancer cells with precision.

What is superficial radiation treatment?

Superficial radiotherapy is a type of external radiotherapy. It treats cancer on or close to the skin surface. Superficial radiotherapy means that the radiation doesn’t travel far into your body. You can have superficial radiotherapy with low energy x-rays (photons) or electrons.

Can SRT make you tired?

Some patients may experience some short-term side effects, such as headache, gastrointestinal upset, or fatigue.

Is IG SRT effective?

Image Guided Superficial Radiotherapy [IG-SRT] is a safe and effective alternative to surgery for Squamous and Basel cell carcinomas.

Who made radiotherapy?

In 1896 a German physics professor, Wilhelm Conrad Roentgen, presented a remarkable lecture entitled “Concerning a New Kind of Ray.” Roentgen called it the “X-ray”, with “x” being the algebraic symbol for an unknown quantity. There was immediate worldwide excitement.

What conditions are treated with superficial and orthovoltage radiotherapy?

Conditions treated with superficial and orthovoltage radiotherapy. Superficial and orthovoltage radiotherapy are used for the treatment of skin lesions such as melanoma, squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) as well as non-malignant skin conditions such as keloids.

What is superficial basal cell carcinoma?

Abstract Superficial basal cell carcinoma comprise up to 25% of all histological sub-types. They are more likely to occur on younger persons and females and although generally more common on the trunk, also occur frequently on the exposed areas of the head and neck especially in areas of high sun exposure.

Is orthovoltage the best treatment for bone metastases?

Relatively high absorption of these low energy x-rays in bone also means that orthovoltage treatment is well suited to the palliative treatment of painful bony metastases in shallow regions such as the ribs and sternum.

What are supersuperficial and orthovoltage (DXT) radiotherapy?

Superficial (SXT) and Orthovoltage (DXT) radiotherapy utilise low energy ionizing radiation to treat cancer and other conditions that occur either on or close to the skin surface.
