__________ uses high-frequency sound waves that reflect off tissues and organs. The reflected waves are detected and converted into images.

__________ uses a strong magnetic field and radio waves to generate detailed images of internal body structures. It is highly effective for visualizing soft tissues and organs.

__________ involve injecting a small amount of radioactive material into the body. This material emits positrons, which interact with electrons to produce gamma rays detected by the scanner.

In X-ray technique, dense structures like bones absorb _______ X-rays, creating clear images.

__________ is the smallest unit in a digital image. It represents a single point in the image and has a specific intensity value.

In grayscale images, ____________ colors are used.

__________ pixels are those adjacent to a given pixel.

__________ measures the similarity in intensity between neighboring pixels. High correlation indicates that adjacent pixels have similar values, which is common in homogeneous regions.

__________ improves the visual quality of medical images. Techniques like contrast stretching, histogram equalization, and filtering are used to highlight important features and make them more visible for diagnosis.

In medical images, ____________ separates regions of interest from the background.
