Overview

An MRI coil receives radiofrequency signals from the body to form images. Coils are designed for specific anatomy to improve signal to noise. Proper coil selection enhances diagnostic quality.

Types and Uses

Surface coils phased array coils and volume coils serve different clinical needs. Dedicated coils exist for head spine breast and cardiac imaging. Coil geometry affects image uniformity and resolution.

Handling and Care

Coils require careful handling to avoid damage and preserve performance. Regular inspection and cleaning prevent artifacts and infection risk. Manufacturer guidelines should be followed for maintenance.

Compatibility

Coil compatibility with scanner models and software is essential. Firmware updates and connectors must match vendor specifications. Verification testing ensures safe and effective operation.

Overview

An ultrasound probe converts electrical energy into sound waves and back to form images. Probe frequency and footprint determine penetration and resolution. Proper probe selection matches clinical application.

Probe Types

Linear convex and phased array probes serve vascular abdominal and cardiac imaging. Endocavitary probes are used for transvaginal and transrectal studies. Each probe requires specific handling and sterilization.

Care and Sterilization

Probes must be cleaned and disinfected according to guidelines to prevent infection. Cable strain relief and connector care extend probe lifespan. Regular performance checks detect element failure and artifacts.

Integration

Probes interface with ultrasound consoles and software for image processing. Firmware updates and compatibility affect advanced features like elastography. Training ensures optimal image acquisition and interpretation.
