The implementation of knowledge‐based planning with partial OAR contours for prostate radiotherapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Intra‐ and inter‐observer contour uncertainty is a continuous challenge in treatment planning for radiotherapy. Our proposed solution to address this challenge is the use of partial contours for treatment planning, focusing on uninvolved or non‐overlapping portions of the organs‐at‐risk (OARs) with the planning target volume (PTV ...

Sand-Filler Structural Material with Low Content of Polyethylene Binder [PDF]

, 2020
Currently, most of the waste plastics cannot be recycled, causing serious environmental concerns. In this research, we investigated a compaction formation technology to fabricate structural materials with thermoplastic binders. When the compaction pressure was 70~100 MPa, with only ~10 wt% polyethylene binder, the flexural strength was greater than ...

Feasibility study of skin dosimetry with TLD sheets for measuring the effect of 3D printed bolus in radiotherapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract The thermoluminescence dosimeter (TLD) sheet is a measurement device coated with manganese‐doped LiB3O5 in sheet form. The sheet is 0.2‐mm thick and flexible. Hence, it can fit and be installed on irregular surfaces. The current study aimed to evaluate the feasibility of measuring patient surface doses during radiation therapy using TLD sheets.

Growing Sweetcorn in Alaska's Cool Environments [PDF]

, 1966
Sweet corn can be grown in Alaska's cool environments by employing clear polyethylene mulch to raise soil temperatures. Rows should be run north and south, spaced about 5 feet apart for 4-foot wide mulch.
