Question

Each of the following statements is true about taking x-rays using the paralleling technique except:

a) It requires precise film and sensor placement.
b) It minimizes distortion and anatomical errors.
c) It involves placing the film sensor at an angle.
d) It utilizes a beam alignment device for accuracy.

Answer 1

The paralleling technique in x-ray imaging does not involve placing the film sensor at an angle.

Step-by-step explanation:

The correct answer is c) It involves placing the film sensor at an angle.

The paralleling technique is a method used to take x-rays in dentistry. This technique involves placing the film or sensor parallel to the long axis of the tooth being examined, using a beam alignment device to ensure accuracy. The film or sensor is placed right against the teeth, without any angulation.

The other statements are true:

1. a) It requires precise film and sensor placement: This is true because the film or sensor must be placed in the correct position to capture the desired image.
2. b) It minimizes distortion and anatomical errors: This is true because the paralleling technique reduces distortion and provides a more accurate representation of the teeth and surrounding structures.
3. d) It utilizes a beam alignment device for accuracy: This is true because a beam alignment device, such as a positioning indicator, is used to ensure that the x-ray beam is directed properly and accurately.
