A radiographic examination that incorporates the application of pressure or pressure devices to confine the administration of contrast media exclusively to a specific area of interest.  

A mechanical mechanism designed to diminish the thickness of a particular anatomical region, aiming to enhance the quality of radiographic examinations, is employed in medical imaging. One variant of this apparatus finds utility in intravenous pyelography (IVP) procedures, primarily serving the purpose of compressing the ureters. Additionally, other types of such devices are utilized during…

An adjunctive apparatus employed during fluoroscopy procedures of the gastrointestinal (GI) tract facilitates the examiner in exerting pressure on specific regions under examination. This device aids in displacing certain overlying structures, thereby enhancing the quality of radiographic evaluations performed during the procedure.  

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.  

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.  …

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.  

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.  

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.  

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…

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.
