A system and method for validating the accuracy of delineated contours in computerized imaging using statistical data for generating assessment criterion that define acceptable tolerances for delineated contours, with the statistical data being conditionally updated and/or refined between individual processes for validating delineated contours to thereby adjust the tolerances defined by the assessment criterion in the stored statistical data, such that the stored statistical data is more closely representative of a target population. In an alternative embodiment, a system and method for validating the accuracy of delineated contours in computerized imaging using machine learning for assessing delineated contours, with the machine learning training data being used to generate geometric attributes, and the geometric attributes used to construct intra- and interstructural geometric attribute distribution models to automatically detect contouring errors. The present invention may be used to facilitate, as one example, radiation therapy.

A system and method for validating the accuracy of delineated contours in computerized imaging using statistical data for generating assessment criterion that define acceptable tolerances for delineated contours, with the statistical data being conditionally updated and/or refined between individual processes for validating delineated contours to thereby adjust the tolerances defined by the assessment criterion in the stored statistical data, such that the stored statistical data is more closely representative of a target population. The present invention may be used to facilitate, as one example, on-line adaptive radiation therapy.

A cup includes two compartments in a unitary structure: an upper compartment that holds the liquid drink and a lower compartment that has a configured slot to slide onto the edge of a plate. The upper compartment has an open top-end and a closed bottom-end just like any other cup. The open top-end is larger than the closed bottom-end so as to permit stacking multiple cups together. The lower compartment is connected below the closed bottom-end of the first compartment. The second compartment defines a configured slot or cut-out that is shaped to receive the edge of a plate and contact the bottom of the plate. The cut-out starts with a wide slot at the wall of the cup that transitions to a narrow slot within the cup. The narrow slot is intended for the edge of the plate. The wider slot contacts the bottom of the plate.

An adjustable animal feeder holder for preventing crawling insects from accessing an animal feeder placed thereon comprising a container having a bottom surface and an integral side wall extended upwards from the bottom surface; a platform mechanism coupled to the bottom surface of the container, extended upwards therefrom, and adapted for holding an animal feeder placed thereupon; and an adjustable mechanism coupled to the platform mechanism for adjusting the height of the platform mechanism above the container; whereby when an animal feeder having animal feed disposed therein is placed upon the platform mechanism and liquid is disposed in the container, a moat is created, and the moat prevents crawling insects from accessing the animal feed.
