A patient is positioned on the carbon fiber treatment couch for pelvic treatment. The radiation therapist needs to shift the couch superiorly to align the patient’s treatment marks with the room lasers. According to standard nomenclature, which translation axis and coordinate direction represent this superior-inferior movement?

A patient is being treated in x-ray (photon) mode. Place the following components in the correct order the beam encounters them: I. Target II. Scattering foil III. Flattening filter IV. Ion chamber

What happens if the scattering foil is composed of a layer of high-Z material that is too thick?

Above is a diagram of an electron transport chain. Below you will consider two scenarios where mutations have occurred that altered the functions of the components.  1. If a mutation destroyed the ability of protein I to pump protons, how would that impact ATP generation and why? (4 points) 2. If a mutation destroyed the ability of protein I to transfer electrons, how would that impact ATP generation and why? (4 points)
