Magnetic Resonance Elastography (MRE) datasets for agar phantom, healthy human brain and liver

The dataset comprises three types of MRE data:1)    Agar Phantom Data: Generated from a self-made agar phantom containing two inclusions—one hard and one soft—embedded within the gel.2)    Brain Data: Acquired from the brain of a healthy volunteer.3)    Liver Data: Collected from the liver of a healthy volunteer.All datasets were acquired using four vibration frequencies (30 Hz, 40 Hz, 50 Hz, and 60 Hz), with slice acquisition performed along the z-axis. The data are organized into four distinct categories with the following structure: 1)    PhaseRaw (Raw phase data) a)      Unit: Radians b)      Dimensions: [x, y, z, phase offset, displacement direction, vibration frequency] c)      Note: For each acquisition, four phase offsets were recorded, and each phase offset includes two displacement encodings (positive and negative). Therefore, there are a total of 8 phase offsets data, among which the odd-numbered ones are positive encodings and the even-numbered ones are negative encodings. 2)    U (Displacement field) a)      Unit: Radians b)      Dimensions: [x, y, z, phase offset, displacement direction, vibration frequency] 3)    Mag (Magnitude images) a)      Dimensions: [x, y, z, phase offset, displacement direction, vibration frequency] b)      Note: For each acquisition, four phase offsets were recorded, where positive and negative displacement encoding corresponded to odd- and even-numbered phase offsets, respectively. 4)    G (Complex shear modulus) a)      Unit: Pascals (Pa) b)      Dimensions: [x, y, z] c)      Note: the real part represents the storage modulus and the imaginary part represents the loss modulus.
