What is intensity Modulated brachytherapy?

Purpose: Intensity modulated brachytherapy (IMBT) is a novel high dose rate brachytherapy (HDR BT) technique which incorporates static or dynamic shielding to increase tumor coverage and/or spare healthy tissues.

What is intensity modulated radiation therapy used for?

Intensity modulated radiation therapy, or IMRT , is used to treat cancerous and noncancerous tumors. Radiation beams fit the shape of the tumor. The goal is to target the radiation to limit side effects and damage to healthy tissue.

What is the difference between 3DCRT and IMRT?

3-dimensional conformal radiotherapy (3DCRT) (1-3) is used to confine the radiation dose to PTV but intensity modulated radiotherapy (IMRT) (4-8) have an additional advantage of sparing the organs at risk (OAR).

What is the difference between EBRT and IMRT?

IMRT is a special form of EBRT involving the delivery of hundreds of small radiation beams with different intensities, entering the body from a number of different angles.

Why is IMRT better than 3DCRT?

Our data suggest that IMRT-delivered high radiation dose produces significantly less average percent volumes of irradiated lung and heart than 3D-CRT. IMRT is superior to 3D-CRT in the OS of EC while shows no benefit on radiation toxicity.

Which is better Igrt vs IMRT?

IGRT uses imaging with the therapy to increase the efficiency by improving the precision and accuracy of the treatment procedure. The IMRT therapy uses high-edged software and sophisticated hardware to vary the intensity and shape of radiation used for different parts of the treatment area.

What is intensity-modulated brachytherapy?

More recently, techniques using a shielded applicator or source to modulate the intensity of the radiation dose during BT delivery, or intensity-modulated brachytherapy (IMBT), have been investigated.

Is direction-modulated brachytherapy effective for high-dose-rate treatment of cervical cancer?
