CT Scanner Slip Ring Quiz

What is the primary function of a slip ring in CT scanners?

• To generate X-rays

• To allow continuous rotation of the gantry without tangled cables

• To enhance image resolution

• To reduce patient radiation exposure

Which year was slip ring technology introduced in CT scanners?

• 1980

• 1990

• 2000

• 2010

What type of material is used in composite slip ring brushes to prevent arcing?

• Copper

• Silver graphite alloy

• Aluminum oxide

• Titanium

What is the advantage of contactless slip ring technology introduced by GE?

• Uses optical fibers for data transfer, reducing electromagnetic interference (EMI)

• Increases the size of the gantry for better scanning

• Allows only short-duration scanning

• Uses vacuum-sealed components to prevent overheating

Which design of slip ring consists of conductive rings positioned along the axis of rotation to form a cylinder?

• Disk design

• Pancake design

• Cylindrical design

• Helical design

In a low-voltage slip-ring system, where is the high-voltage transformer positioned?

• Inside the gantry

• Outside the gantry

• Inside the X-ray tube

• In the patient table

What is the primary function of CT scan filters?

• To improve X-ray tube efficiency

• To enhance image quality and reduce patient radiation exposure

• To increase the scanning speed

• To replace the collimator

What are the two main types of CT scan filters?

• Pre-patient and Post-patient filters

• High-energy and Low-energy filters

• Adaptive and Fixed filters

• Digital and Analog filters

Which material is commonly used in CT scan filters to block low-energy X-rays?

• Gold

• Copper

• Lead

• Silicon

What is the role of the Data Acquisition System (DAS) in CT imaging?

• It generates the X-ray beams

• It stores CT images for later review

• It processes and converts signals from detectors into digital data for image reconstruction

• It controls the movement of the patient couch
