For PTVs, RA-C delivered lower maximum and mean doses and improved conformity and homogeneity compared with RA-FFF.
In the matters of homogeneity and conformity of the target volume, the results are in disagreement: some studies showed an advantage of VMAT, reporting improved conformity or homogeneity, while other studies observed better results with fixed-field IMRT.
IMRT represents a new generation of technology and, as compared with 2DCRT and 3DCRT, has better dosimetric advantages, improved conformity and uniformity of treatment targets, and better-protected OARs [ 4].
Failure to improve conformity rates for several indicators, including serum albumin, was found, possibly depending on patients' comorbidities rather than on quality of care.
The response we will give to this need is the 3C Meta-Standard Framework, an effort to create a "Standard for Standards", a universal architecture for standards that allows assessing compliance with Non-technical standards and improve conformity assessment with Technical ones.
This is followed by an optimization procedure, using a variational formulation of active contours, that seeks to improve boundary mesh conformity to the zero level contour of the level set function.
Studies in breast cancer patients comparing tomotherapy with 3D-planning demonstrated a minimal dose increase but improved dose homogeneity and conformity to the planning target volume [ 13].
Studies have shown that conformity to approved treatment guidelines is improved when patients are treated by an MDT in a reference centre [1].
To improve the conformity of the RTs to a normal distribution, we analyzed the log of the RT data using a 2 × 3 × 5 repeated measures ANOVA in SPSS 11.0.1 with inversion, delay, and reference distortion as repeated measures factors.
Genetic diversity would be measured by visual observation of the herd's conformity to type using a visual system developed by Dr. Sponenberg, and measures taken to improve genetic diversity if signs of inbreeding occurred.
