A gradient is a gradual transition between two or more colors. Gradients are usually applied as either a linear or a radial fill. A linear fill gradient causes the color blend to flow from the first color to the next in a straight line. For example: An image can have a blue top that gradually blends into a green bottom. A radial fill gradient causes the color blend to flow from the center of the first color to the next in a circular pattern surrounding the point selected. For example: An image can have an orange center that gradually blends into a green field surrounding it.

Pressure difference...the term "gradient" is used to specify the difference in blood pressure before and after a blockage or stenosis. The gradient is a pressure difference (calculated by subtracting the higher pressure before a blockage from the lower pressure beyound the blockage). The severity of a blockage and the impact on circulation hemodynamics can be estimated by the magnitude of the gradient. This is particularly useful in estimating the severity of obstructive heart valve conditions.

1. The space rate of decrease of a function. The gradient of a function in three space dimensions is the vector normal to surfaces of constant value of the function and directed toward decreasing values, with magnitude equal to the rate of decrease of the function in this direction. The gradient of a function is denoted by âˆ’âˆ‡ (without the minus sign in the older literature) and is itself a function of both space and time. The ascendent is the negative of the gradient. In Cartesian coordinates, the expression for the gradient is For expressions in other coordinate systems, see Berry et al. (1945). 2. Often loosely used to denote the magnitude of the gradient or ascendent (i.e., without regard to sign) of a horizontal pressure field. Berry, F. A., E. Bollay, and N. Beers, 1945: Handbook of Meteorology, 224â€“225.
