Detailed video covering the X-Ray circuit and primary x-ray circuit
Please visit www.radtechbootcamp.com to view the rest of this series in addition to our other video lessons.
This video covers the anatomy of the x-ray circuit
The total x-ray circuit is really three combined circuits:
– The primary circuit
– The secondary circuit
– The filament
Each of these circuits support the procedure of x-ray production in different methods. This lesson is about the primary circuit …
We call this the “main circuit” due to the fact that this is where the primary power supply enters the x-ray machine and it consists of among the most important parts of the primary circuit called circuit breaker.
– The circuit breaker is one of the very first components in the circuit because it secures the rest of the circuit – The purpose of the breaker is literally to BREAK the circuit, and stop the incoming electrical power from moving into the x-ray machine. So … why would we want that to take place?
– Usually we don’t want that to happen, however if the machine attempted to draw excessive power the entire circuit might be damaged.
– The circuit breaker breaks the circuit before the remainder of the circuit can get harmed.
X-ray circuit.
The staying elements of the main circuit all relate to the primary direct exposure elements, especially the kVp. They are:
– Line voltage-compensator
– Autotransformer
– Exposure timer
– Step-up transformer
The main circuit includes a device called a line-voltage compensator.
– The power is supposed to come in from the electrical company as 220 V, however it can differ some. Can you envision paying full price for only 95% of a gallon of milk? That’s how electrical energy works.
– The voltage in an x-ray maker needs to be exceptionally accurate, so a gadget called a “line-voltage compensator” measures the voltage and remedies it to exactly 220 V.
– In others words, it COMPENSATES for the incoming voltage being slightly off.
It’s fantastic that we remedy the electrical power to exactly 220 volts, but 220 volts isn’t adequate to make an x-ray. In radiography, we need to utilize MORE than one voltage setting AND we require kilovolts, not volts.
– When the technologist sets the kilovoltage potential (kVp), this modification occurs in the circuit through a gadget called an “autotransformer”.
– Utilizing a single coil of wire and a procedure called self-induction, the device sets the kilovoltage to be utilized during the direct exposure.
– This makes good sense because “vehicle” suggests “self” or “one”. The AUTO-transformer sets the kVp using ONE coil of wire through a procedure called SELF-induction.
– The kVp meter is linked to this part of the circuit
Direct exposure timer is positioned in the main side of the circuit to control for how long the exposure remains on. This makes sense …
– The x-ray direct exposure takes place only when the voltage (kVp) is used to the x-ray tube.
– Since primary circuit controls the kVp, it makes good sense that the exposure timer requires to be in the primary circuit.
The last part of the primary circuit is the step-up transformer, or technically the PRIMARY side of the transformer.
X-ray circuit.
– Up till this part, the electricity is still in VOLTS, but in x-ray we require KILOVOLTS.
– The step-up transformer boosts (or “actions up”) the voltage from volts to kilovolts.
– A step-up transformer utilizes a procedure called shared induction. If you make a MUTUAL choice with someone, that’s a decision in between two individuals. In this instance, mutual induction is made by two sets of coils.
– Likewise discover the 2nd set of coils has more turns that the very first set. This informs us that we are “stepping up” from voltage to kilovoltage. The area in between these two coils serves as the division line in between the main and secondary circuits.
That’s a summary of the x-ray circuit of the x-ray device The main circuit gets the main power supply and several components related to the voltage …
– A circuit breaker to safeguard the device.
– A line-voltage compensator to remedy the voltage to exactly220
– An autotransformer to select the wanted kVp
– The kVp meter
– The step-up transformer to alter the electricity from voltage to kilovoltage.
