Select the three factors from the choices below that determine the size of the actual focal spot on the target anode.

A focal spot in the x-ray setup is the area of the anode surface which receives the beam of electrons from the cathode. It is the apparent source of x-rays.

Below are some of the factors that affect its size.

Explanation:

Size of the focal spot depends on

* angle of the anode

Other prime factors that affect x-ray emission; under the control of the radiographer includes;

• Miliamperage-second (mAs)(tube current measurement)

• Kilovoltage (kVp) Controls both the quantity and quality of the x-ray beam with the speed and energy.

• Distance (d) - Related to tube design and construction.

• Tube housing

• Target material

• Filtration

• Voltage waveform

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
