I am working in a research and my hypothesis is ( The CT Dose Index (CTDIvol) was originally designed as an index not as a direct dosimetry method for patient dose assessment. There is no current method for calculating peak skin dose (PSD) using key metric provided from the radiation dose structure report of a CT scanner. Since every CT is required that each study has to output the dose, product and CT dose index volume, there is no direct method to go straight to the PSD. This project will test if the Size Specific Dose Estimate (SSDE) has a strong linear relationship with the peak skin dose. )
What I want is that others have contributed to your field historically, philosophically, or experimentally. What closely related problems, ideas, or solutions will you build on and use in your research? What contribution do you expect your research to make to the literature?
Here is the articles which are similar to mine and I want you to use:
https://pubmed.ncbi.nlm.nih.gov/33955655/
https://pubmed.ncbi.nlm.nih.gov/34311161/
that is what I am doing:
The CTDIvol displayed by the scanner will be validated to the true CTDIvol following the ACR testing guidelines. A correction factor will be used to correct any inaccuracies in the displayed value. This correction will also be applied to the DLP displayed by the scanner.
Peak skin dose and its relation will be measured by various phantoms such as NEMA phantoms, 16 cm CTDI and 32 cm CTDI phantoms. The phantoms will be aligned at the isocenter of the scanner with the chamber in the center hole of the phantom. The longitudinal axis of the chamber and cylindrical phantom will be aligned parallel to the longitudinal axis of the CT gantry. With using those different phantoms, the dosimeter will be placed serially in center hole ad peripheral hole. Those measurements are combined to produce the weighted CTDI, so a 100-mm-long cylindrical (pencil) chamber, approximately 9 mm in diameter, inserted into either the center or a peripheral
