Question

The timing of a cine camera shutters and emitted x-ray pulsed are governed by?

1. the patient thickness/density
2. the framing frequency
3. automatic brightness control system
4. automatic exposure control

Answer 1

The timing of cine camera shutters and emitted x-ray pulses in medical imaging is managed by systems within the x-ray machine such as the automatic brightness control system, framing frequency, and automatic exposure control.

Step-by-step explanation:

The timing of a cine camera shutter and emitted x-ray pulses in medical imaging are governed by a variety of factors that ensure the correct exposure and protect patient safety. These factors are typically managed by sophisticated systems within the x-ray machine. These include:

1. Automatic brightness control system - This adjusts the exposure based on the amount of light required to produce a clear image taking into account patient thickness and density.
2. Framing frequency - This dictates the number of images captured per unit time and can affect the blurriness or sharpness of moving objects.
3. Automatic exposure control - An advanced feature used to automatically set the optimal exposure, reducing the amount of radiation to the patient.

The correct exposure is crucial in medical imaging and involves a balance between patient safety (minimizing radiation dose) and image clarity.
