How X-Ray Collimators Work: Beam Shaping, Optics & Scatter Reduction
In diagnostic radiography, controlling the primary X-ray beam is a fundamental requirement for achieving high-contrast images and ensuring strict radiation protection. Unrestricted X-ray beams irradiate tissue outside the clinical area of interest,…
Complete Guide to Rectifiers: Half-Wave, Full-Wave & Bridge Circuits
Rectifiers are electrical circuits that convert Alternating Current (AC), which reverses direction periodically, into Direct Current (DC), which flows in only one direction. This process is known as rectification. 1. Core Principle of Rectification…
Rectification in an X-Ray Circuit
Rectification in an X-Ray Circuit: This is the electrical process of converting high-voltage Alternating Current (AC) from the step-up transformer into Direct Current (DC). This ensures an uninterrupted, unidirectional stream of projectile electrons…
Filament Circuit in X-Ray Tube
Filament Circuit in X-Ray: The filament circuit is a dedicated sub-circuit within the X-ray generator designed to deliver low voltage and high current to heat the tungsten filament in the cathode. This process produces free electrons via thermionic…
Kilovoltage (kVp) Control Circuit in X-Ray
Kilovoltage (kVp) Control Circuit: The kVp control circuit (or primary high-voltage circuit) regulates the primary voltage delivered to the step-up transformer in an X-ray generator. It directly sets the peak potential (40 to 150 kVp) across the X-ray…
Single-Phase X-Ray Generator
Single-Phase X-Ray Generator: A single-phase generator is an electrical power system that operates on a single sinusoidal alternating current (AC) waveform (typically 220 to 240 V at 50 or 60 Hz) to establish high-voltage potential across an X-ray tube.…
