Interactive calculator for Rad Techs for x-ray stopping power of different materials (water, lead, air, etc).

An interactive calculator for answering the question: what is the thickness of material A that we would need to match the x-ray transmission through a given thickness of material B. For instance how much water is equivalent to 1mm of lead in stopping an 50 keV x-rays? If you have been loosing sleep over such …

Hands on Calculator for Technical Parameters In CT Imaging, and their effect on patient dose

A review of radiation dose measurements in CT and a calculator for changing multiple technical parameters (kVp, pitch, s) and observing the effect on the mA needed to keep the dose relatively constant. We also provide a couple use cases that would motivate changing the technical parameters of a protocol at the time of scanning. …

Interactive X-Ray Transmission Calculator for Radiologic Technologists (Beer’s Law Equation)

This is a calculator the transmission, (fraction of the x-ray beam), that will penetrate different thickness of materials such as water, bone, air and lead. This calculator is useful to get a sense of what fraction of the x-ray beam will pass through different objects. The calculator has the option for a few energies of …
