What is the term for an arrangement of columns or rows of cells, forming a digital image?

The term "image matrix" refers to the grid-like arrangement of rows and columns of cells (or pixels) that collectively form a digital image. In this context, each cell within the matrix contains specific information about color, brightness, or grayscale, allowing for the representation of detailed images. The matrix format is fundamental in digital imaging as it provides structure and organization to how images are represented and processed in various imaging modalities, including those used in vascular interventions.

Dynamic range refers to the range of intensity levels that an imaging system can capture, influencing the overall quality and detail of the image but not the structure of the image itself. Digital image subtraction is a technique used to enhance images by removing overlapping structures, and it also does not pertain to the fundamental arrangement of an image. Data range typically pertains to the variance of values in a dataset and is not specifically linked to the format of digital images. Thus, "image matrix" is the precise term that describes the organized layout of cells that compose a digital image.
