Partial volume is a phenomenon in imaging and signal analysis where the measured signal is a composite of different material properties within a voxel or pixel. This can lead to inaccuracies in image representation and challenges in quantifying structures, necessitating advanced methods for correction or compensation.

Imaging is the process of creating visual representations of an object or scene for the purpose of analysis, diagnosis, or understanding. It spans multiple disciplines, including medical imaging, satellite imaging, and digital photography, each utilizing different technologies to capture and interpret images.

Signal analysis is the process of examining, manipulating, and interpreting signals to extract meaningful information, often using mathematical and computational techniques. It is crucial in various fields such as communications, engineering, and data science, enabling the enhancement, compression, and transmission of information.

A voxel is like a tiny cube that helps computers make 3D pictures, kind of like how pixels make 2D pictures. Imagine building a big castle out of tiny blocks, where each block is a voxel helping to create the whole castle in a computer game or a movie.

Voxel

A pixel is the smallest unit of a digital image or display, representing a single point of color. Pixels collectively form the grid that makes up the visual output on screens, with their density and arrangement determining the resolution and clarity of the image.

Compensation refers to the total financial and non-financial rewards given to employees in exchange for their work, encompassing salary, benefits, bonuses, and other incentives. It plays a crucial role in attracting, retaining, and motivating employees while aligning their objectives with organizational goals.
