ePin

ePin is a shareware for film dosimetry. It allows the user to insert virtual pin marks into the RTP generated dose map to facilitate image registration for patient-specific IMRT QA procedure.
Sensitometry analysis, image format conversion and dosimetrical film calibration are also included in later versions.

It is a small program running on Microsoft Windows platforms.
What it does is basically to put virtual fiducial marks in planar dose map at corresponding points where the measuring film is supposedly pricked. Currently it supports PINNACLE®, FOCUS®, NOMOS®, HELAX®, ECLIPSE® and PLATO® RTP systems. It works well with RIT113® film dosimetry system. It also features a sensitometry QA module. Bit by bit more modules such as image format conversion, dosimetrical film calibration for both LINAC-based and TomoTherapy® IMRT QA were added. It is intended for research purposes only. You can download it and use it at your own risk. Should you have any questions or suggestions, please feel free to contact us by email Yulong.Yan@utsouthwestern.edu or phone (214)645 7636.

Happy pinning from the ePin team.
