FOCUSED OSCILLATION DEVICE
PROBLEM TO BE SOLVED: To solve such the problem that the conventional oscillation device can not be used for finding a small hardness change in an early stage since it is hard in the device to control the frequency, amplitude, and phase, etc., of oscillation to be generated, and, for example, the de...

| description | PROBLEM TO BE SOLVED: To solve such the problem that the conventional oscillation device can not be used for finding a small hardness change in an early stage since it is hard in the device to control the frequency, amplitude, and phase, etc., of oscillation to be generated, and, for example, the device is not suitable in the case of a narrow measurement object and not suitable for measuring the minute distribution of viscoelastic moduli though it is suitable for obtaining the average value of the viscoelastic moduli in the wide range area of the measurement object. SOLUTION: The focused oscillation device is used for an MR imaging apparatus or a magnetic resonance microscopy apparatus in order to acquire an image for identifying viscoelasticity of a subject by NMR. The device includes: a plurality of oscillation generating parts for generating oscillation to be given to the subject; a signal generating part for giving a signal for oscillation generation to the oscillation generating parts; and vibration transmission chips which are arranged between the oscillation generating parts and the subject and directionally disposed in a focus area, so that the generated vibration can be propagated inside the subject as an elastic wave and focused in the focus area.
