Key result
A simplified method using a sonic digitizer and programmable calculator allows for rapid, accurate analysis of echocardiographic data with 0.1 mm resolution as an alternative to expensive computers.
A simplified, inexpensive method using a sonic digitizer and programmable calculator allows for rapid and accurate analysis of echocardiographic data.
May enable low-cost echocardiographic analysis in limited settings; leaves open validation against modern digital platforms.
Rapid accurate analysis of echocardiographic data is accomplished using a sonic digitizer and programmable calculator. This method allows the echocardiographer to select technically optimal areas of the recording for analysis. The resolution of the measuring device is 0.1 mm. A hardcopy printout of both measurement and calculation is provided. Instead of expensive on-line computer, an inexpensive programmable calculator is used.
