 ## Dataset Description
 
-Real, **in-vivo human** pre-beamformed ultrasound **channel data** for bladder
-imaging: per-element I/Q recorded before receive beamforming on a 64-element
-phased array — a sector scan of 180 transmit beams steered over ±45.13° (≈90°),
-one image line per transmit (steering angles in `scan.polar_angles`). 1,508
-frames across 14 sweeps from seven subjects. Acquired on a GE research system in
-tissue-harmonic mode; the harmonic echo is demodulated to I/Q at 3.44 MHz and
-band-pass filtered. No paired image is supplied — the B-mode is reproduced from
-the channel data by the released beamformer.
