During a portable, it is crucial that the tube and the image receptor are at 90 degrees of each other or else _______ can occur. 

! Our original technique was 60 kVp with 4.2 mAs. We want to double the IR Exposure while also creating a longer scale of contrast. What will our new technique be?

What is the magnification factor when the image size of a tumor was recorded at 1.3”, the SID used was 44”, the OID was 3”, the kVp was 80, the mAs was 2.5, and the focal spot size was 1”?

When an x-ray is created using 60 kVp, how much of the beam is Brem’s radiation?

What photon energy is produced by a tungsten anode if the L-shell electron vacancy is filled by an M-shell electron? Approximate electron binding energies are listed for tungsten: K shell = 69.5 keV, L shell = 12 keV, M shell = 2 keV, N shell = 1 keV.

When the current only flows in one direction, it is known as:

* A technologist is going to perform a portable chest x-ray in the ED. Due to equipment limitations and patient condition, the IR is placed 8 cm behind their back. The SID is 180 cm, standard for chest imaging. They use a 1.2 mm FSS. What is the magnification factor of the heart on this radiograph?  

An atom is ionized after incident electron knocks out an inner shell e- during a characteristic interaction. 

The rectification bridges within the x-ray circuit function to modify the electrical power within the x-ray system by converting:

K-Characteristic x-rays on a Tungsten anode, require a tube potential of at least:
