Abstract
An elastography method implemented by an elastography device, the method including obtaining a respiratory signal related to a respiratory activity of a subject; and acquiring a plurality of measurements of a mechanical property of a region of a body of the subject, the region being a part of a liver or a spleen of the subject, wherein each measurement among at least a subset of the plurality of measurements of the mechanical property is acquired at a same moment of a respective respiratory cycle determined from the respiratory signal.
Claims20
An elastography method implemented by an elastography device, the method comprising:
- obtaining, using a respiratory sensor, a respiratory signal related to a respiratory activity of a subject;
- and
- acquiring, using an elastography probe of an elastography device, a plurality of measurements of a mechanical property of a region of a body of the subject, the region being a part of a liver or a spleen of the subject;
- wherein each measurement among at least a subset of the plurality of measurements of the mechanical property is acquired at a same moment of a respective respiratory cycle determined from the respiratory signal.
An elastography system comprising an elastography probe and an electronic unit including a processing circuit, the electronic unit being configured to:
- receive a respiratory signal, from a respiratory sensor, related to a respiratory activity of a subject, and
- acquire a plurality of measurements of a mechanical property of a region of a body of the subject, the region being a part of a liver or a spleen of the subject;
- wherein each measurement among at least a subset of the plurality of measurements of the mechanical property is acquired at a same moment of a respective respiratory cycle determined from the respiratory signal.
A non-transitory computer readable storage medium, having stored thereon a computer program comprising program instructions, the computer program being loadable into a data-processing unit and adapted to cause the data-processing unit to carry out the steps of an elastography method when the computer program is run by the data-processing device, the elastography method comprising
- obtaining, using a respiratory sensor, a respiratory signal related to a respiratory activity of a subject;
- and
- acquiring, using an elastography probe of an elastography device, a plurality of measurements of a mechanical property of a region of a body of the subject, the region being a part of a liver or a spleen of the subject;
- wherein each measurement among at least a subset of the plurality of measurements of the mechanical property is acquired at a same moment of a respective respiratory cycle determined from the respiratory signal.
The elastography method of claim 14, wherein the low-frequency vibrator has a central average frequency lower than 500 Hz.
