volume. Teletherapy uses a device located at a distance from the patient, as is the case in most orthovoltage or supervoltage machines. The advent of high voltage teletherapy for deeper tumors and the problems associated with radiation exposure from high-energy radionuclides led to a decline in the use of brachytherapy
Brachytherapy (sometimes referred to as curietherapy or endocurie therapy) is a term used to describe the short distance treatment of cancer with radiation from small, encapsulated radionuclide sources. This type of treatment is given by placing sources directly into or near the volume to be treated. The dose is then
Introduction. Brachytherapy refers to a method of delivering radiation to cancers by placing radioactive sources either directly into the cancer or very close to it. Because the dose rate drops off rapidly as the distance increases from the source, brachytherapy has the advantage of delivering a high dose to the target volume
This book is for men who have made a decision to have a specific treatment or have already received treatment for prostate cancer. It contains information about important issues to help men who need to know about brachytherapy treatment and prostate cancer. PCFA provides a range of resources to support men, partners.
The vertical cross-sectional view of CCB-type applicator with dimensions. 2.1 The beta emission area distribution. In order to distribute the beta emission source area on a concave surface, PDF (Probability. Density Functions) were formulated using spherical functions. The total areas for the CCA- type and for the CCB-type
25 May 2005 Four types of brachytherapy applications are commonly distinguished: – Surface applications: source molds or flexible surface applicators are used to position the sources at a fixed distance from the lesion. (e.g. skin cancer) to be irradiated. – Intracavitary applications: the sources are inserted into a natural.
Brachytherapy places radioactive sources inside the patient on a temporary or permanent basis to damage cancer cells' DNA and destroy their ability to divide and grow. It allows your doctor to use a higher total dose of radiation to treat a smaller area in less time than conventional external beam radiation therapy.
In brachytherapy, the dose is prescribed to an isodose encircling a small target volume, but in contrast with EBRT, the dose distribution is very heterogeneous. It is minimal at distance of the radioactive sources, but much higher doses and dose rates are delivered in their immediate vicinity. The average dose given to the
