Evaluation of a commercially‐available block for spatially fractionated radiation therapy
In this paper, we present the dosimetric characteristics of a commercially-produced universal GRID block for spatially fractioned radiation therapy. The dosimetric properties of the GRID block were evaluated. Ionization chamber and film measurements using both Kodak EDR2 and Gafchromic EBT film were performed in a solid water phantom to determine the relative output of the GRID block as well as...
متن کاملSpatially fractionated radiotherapy (GRID) using helical tomotherapy
Spatially fractionated radiotherapy (GRID) was designed to treat large tumors while sparing skin, and it is usually delivered with a linear accelerator using a commercially available block or multileaf collimator (LINAC-GRID). For deep-seated (skin to tumor distance (> 8 cm)) tumors, it is always a challenge to achieve adequate tumor dose coverage. A novel method to perform GRID treatment using...
متن کاملEvaluation of dosimetric characteristics of a grid block fabricated for Mega-voltage grid therapy purposes
Background: In conventional radiation therapy, regarding normal tissue tolerance, the treatment of bulk tumors is one of the remaining challenges. Grid Radiation Therapy (GRT) is a technique to deliver high doses, approximately 15 – 20 Gy per fraction, to several small volumes located in a large radiation field. This can be performed using a grid block. The current work has concentrate...
متن کاملFractionated Radiation Therapy for Benign Nonacoustic Schwannomas.
OBJECTIVES We analyzed the outcomes of patients with benign nonacoustic schwannomas treated with fractionated radiation therapy (RT). METHODS Between October 1987 and March 2013, 11 patients with benign nonacoustic schwannomas diagnosed radiographically (n=3) or pathologically (n=8) were treated with fractionated RT with curative intent at the University of Florida. We reviewed patients' medi...
متن کاملDosimetric evaluation of parallel opposed spatially fractionated radiation therapy of deep-seated bulky tumors.
Application of a single fraction of parallel opposed GRID beams as a means of increasing the efficiency of radiation delivery to deep-seated tumors has been investigated. This evaluation was performed by measurement of dosimetric characteristics of the GRID radiation field in parallel opposed and single beam geometry. The limitations of the parallel opposed technique in terms of field size and ...
