Description

Disclaimer: This is the first time I am putting a requirement here

Lesions/tumors sizes are generally noted as area or volume in clinical text. The current MeasurementAnnotation annotates only uni-dimensional lengths such as "1 cm". I propose an enhancement of this annotation to be able to detect multidimensional measurements of the form "a x b x c", i.e., numbers delimited by the character 'x'.
