B mode
Brightness modulation refers to a phenomenon wherein echoes are visualized as luminous dots distributed along a reference line, corresponding to the dimension of time. The intensity of brightness is directly linked to the amplitude of the echo, thereby establishing a proportional relationship between the two.

Blooming focal spot
The size of a focal spot has the tendency to expand (referred to as “bloom”) with an increase in milliamperes (mA). Conversely, it diminishes in size with an increase in the target-to-film distance (TFD). In the context of angiography, it is crucial to acknowledge that the focal spot enlarges by approximately 50 percent when transitioning…

Blanking
During the television scanning process, there exists a specific duration known as the retrace period. This period entails the automatic propulsion of the electron beam to the blank level, ensuring a smooth transition and resetting before the subsequent scanning cycle begins.

Black level
The point within the composite video signal where the electron beam of the kinescope display is entirely deactivated, resulting in complete darkness.

Bite-wing
A dental film positioned between the occlusal surfaces of the teeth to assess the alignment and contact between the upper and lower teeth when biting.

Bi-plane
Within specialized procedures, the technique of capturing images from two different angles using a solitary injection of contrast media.

Biological effect
The result that radiation may have on life and living organisms in general.

Binocular stereoscope
The most elementary form of a handheld, portable stereoscopic device consists of two prisms, each with an angle of 20°, wherein one prism is positioned in front of each eye.

Binding energy
The force that secures an electron within its designated shell is referred to as binding energy. Notably, the K shell exhibits the most substantial binding energy, as the K electron maintains the closest proximity to the atomic nucleus.

Beta particles
Electrons of elevated velocity, endowed with the capacity to permeate matter to a more profound extent than alpha rays, manifest their utility in the realm of therapy specifically tailored for addressing superficial skin lesions.
