Definition IMRT is a radiation technique in which the radiation dose in conformed to the 3-dimensional aspects of the tumor, focusing a higher radiation dose on the actual cancer while minimizing the radiation dose delivered to surrounding healthy tissue. IMRT is as effective as conventional radiatio...

The Additional file 1 illustrates the definition of four auxiliary structures. Step 3: Setting optimization objectives and priorities The plan generated from predicted fluence maps already provided the achieved dose information, but the plan quality may need to be further improved. To ensure a plan ...

The target volumes were identical in proton and IMRT plans. Critical structure definition The following critical normal structures were delineated on each planning CT scan: body, spinal cord (defined from 1 cm above the PTV to 1 cm below), heart (defined from apex to aortic valve), esophagus...
Method and Materials: Fields with various degrees of modulation were created using Pinnacle 7.6C to deliver a uniform dose in phantom. Rotated rectangular apertures were used to engage both MLC leafs and jaws in aperture definition. Fields were characterized by an intensity modulation factor (IMF)...
The preoperative MRI was integrated side-by-side in the planning process. Two clinical target volumes (CTV) were generated. For delineation of CTV1, defined as biological target volume from postoperative FET-PET imaging, an auto-contouring process was used. The definition of the biological target...

Image fusion of PET/CT, diagnostic computed tomography, MRI and radiotherapy planning CT as well as target volume delineation was performed with OTP-Masterplan®. Initial gross tumor volume (GTV) definition was based on MRI data only and was secondarily complemented with DOTATOC-PET information. ...
