An AC arm unit, more accurately called a C-arm, is an advanced medical imaging device using X-ray technology. Its distinctive C-shape connects the X-ray source and detector, allowing for versatile imaging during surgical procedures and other medical interventions.
How a C-arm Works
The C-arm's curved design enables it to be positioned around a patient, providing real-time X-ray images (fluoroscopy). This allows surgeons to visualize internal structures and guide instruments with precision. While primarily used for fluoroscopy, C-arms also possess radiography capabilities, producing static X-ray images.
Applications of C-arms
C-arms find extensive use in various medical specialties, including:
- Orthopedics: Guiding bone fracture repair, joint replacement surgery, and spinal procedures.
- Cardiovascular Surgery: Visualizing blood vessels during catheterizations and angioplasties.
- Interventional Radiology: Guiding minimally invasive procedures, such as biopsies and drain placements.
- Trauma Surgery: Assessing injuries and guiding treatment in emergency situations.
Key Features of a C-arm
- Image Intensifier: Converts X-rays into visible images.
- Fluoroscopy Mode: Provides real-time image visualization.
- Radiography Mode: Captures static X-ray images.
- Adjustable Arm: Allows for flexible positioning around the patient.
- Image Processing Capabilities: Offers image enhancement and manipulation features.
In summary: A C-arm is a crucial piece of medical equipment providing real-time X-ray imaging during surgical procedures and various other medical interventions. Its unique design and capabilities make it indispensable in modern healthcare.
