- High-resolution manometry (HRM) is a gastrointestinal motility that measures in the gastrointestinal tract using a series of closely spaced pressure sensors. For a manometry system to be classified as "high-resolution" as opposed to "conventional", the pressure sensors need to be spaced at most 1 cm apart. Two dominant technologies are used: and . Each pressure transduction technology has its own inherent advantages and disadvantages. HRM systems also require advanced computer hardware and software to store and analyze the manometry data. (en)

- This figure shows a pressure topography plot during a normal swallow, measured using a 36-channel high-resolution manometry system. Time is on the horizontal axis and length along the esophagus on the vertical axis. Pressure magnitude is encoded in color corresponding to the scale shown at the bottom. High-pressure regions are denoted by the red end of the spectrum while the low pressure regions by the blue end. Data collected at The University Hospital, Cincinnati and plotted using MATLAB by Sudip K. Ghosh, PhD (en)
