Variable dose interplay effects across radiosurgical apparatus in treating multiple brain metastases
TLDR
The volumes of normal brain receiving 4 and 12 Gy were higher, and increased more swiftly per target, for Linac-based SRS platforms than for PFX, and treatment times were shortest with TrueBeam FFF.
Intrafractional motion of the prostate during hypofractionated radiotherapy.
Simulated real time image guided intrafraction tracking-delivery for hypofractionated prostate IMRT.
TLDR
It is concluded that an on-line target motion monitoring and correction strategy is necessary to implement hypofractionated SBRT with intensity modulated beams for prostate cancer treatments.
Quantitative evaluation of patient setup uncertainty of stereotactic radiotherapy with the frameless 6D ExacTrac system using statistical modeling.
TLDR
Evaluating patient setup accuracy and quantify individual and cumulative positioning uncertainties associated with different hardware and software components of the stereotactic radiotherapy (SRS/SRT) with the frameless 6D ExacTrac system finds mask uncertainty is the largest and varies with patients in the range of (-2.07-3.71mm), while isocentricity of the MV radiotherapy machine is the smallest.
The impact of continuous positive airway pressure on radiation dose to heart and lung during left-sided postmastectomy radiotherapy when deep inspiration breath hold technique is not applicable: a
TLDR
CPAP is applied instead of FB during left-sided breast cancer RT including internal mammary node in a patient who was unable to tolerate DIBH, and substantially decreased radiation dose the heart and lung with CPAP compared to FB.
Normal Brain Sparing With Increasing Number of Beams and Isocenters in Volumetric-Modulated Arc Beam Radiosurgery of Multiple Brain Metastases
TLDR
Multiple isocenter and multiple arc beam delivery solutions are capable of decreasing normal brain irradiation exposure for volumetric-modulated arc radiotherapy, and directly challenged the general notion of dose equivalence among current radiosurgical modalities.
Quantitative evaluation of patient setup uncertainty of stereotactic radiotherapy with the frameless 6D ExacTrac system using statistical modeling
TLDR
Evaluating patient setup accuracy and quantify individual and cumulative positioning uncertainties associated with different hardware and software components of the stereotactic radiotherapy (SRS/SRT) with the frameless 6D ExacTrac system finds mask uncertainty is the largest and varies with patients in the range of (−2.7−3.71mm), while isocentricity is the smallest.
Comparisons of Novalis and CyberKnife® Spinal Stereotactic Body Radiotherapy Treatment Planning Based on Physical and Biological Modeling Parameters
TLDR
To compare treatment planning quality of CyberKnife and Novalis systems for vertebral body stereotactic body radiotherapy, the quality of these systems is compared through simulation and real-time data logging.
