Ultrasound compound scanning
Commonly referred to as sectoring, this technique pertains to the manner in which the transducer is maneuvered across the patient’s body. It entails a series of arcing motions, often necessitating multiple passes over the same area to progressively construct an image with enhanced detail and clarity.

Composite video signal
The comprehensive television signal conveyed from the camera encompasses three fundamental components: video, blanking, and synchronizing pulses. Together, these components constitute the entirety of the transmitted signal, ensuring the seamless transmission of visual content along with the necessary timing and synchronization information.

Ultrasound complex pattern
A recorded structure that exhibits the visual impression of possessing both solid and cystic attributes is commonly referred to as a composite entity. This entity manifests a combination of solid and fluid-filled components, lending it a distinct appearance and characteristics.

Compensating filters
Filtering apparatuses are employed to introduce radiographic density adjustments for anatomical regions that exhibit substantial variations in thickness. This enables the attainment of uniform density across these regions on a specific radiographic image. The aluminum wedge, with its greatest thickness, is strategically positioned at the thinnest part of the body to facilitate this calibration. …

Commutator
An electrical apparatus ingeniously engineered to alter the direction of electrical current is commonly referred to as a device of electrical reversal. Positioned at the extremity of a generator’s armature, this device effectively extracts current intended for the external circuit, permitting its flow in a singularly defined direction.

Collision
An intimate convergence of two or more entities, be they particles, photons, or atomic and nuclear systems, engenders a scenario where an intricate exchange of fundamental attributes transpires. These attributes encompass vital factors such as energy, momentum, and charge.

Cold area
In the realm of radioscopic scanning, an area devoid of any discernible activity manifests, serving as a customary signifier of an underlying anomaly or irregularity.

Coherent scattering
Also known as coherent scattering or classical scattering, Thompson scattering is one of the four fundamental interactions that transpire when photons (x-rays) collide with atoms. In this scenario, a low-energy x-ray photon collides with an inner-orbital electron, but its limited energy is insufficient to dislodge the electron. Instead, the electron can absorb the photon, resulting…

Coaxial cable
A specialized cable employed for transmitting the composite video signal from the camera to the monitor and/or magnetic recorders. The cable features a signal conductor situated at the center, surrounded by a protective grounded metallic sheath.

Closed core transformer
The primary and secondary coils, which are extensively insulated from one another, are wound around a core of a square connected type. This configuration is commonly referred to as a doughnut transformer.
