The left femur bone of a mouse is used for all the data acquisition. Collagenase induced osteoarthritis is performed for different time durations for the same femur bone.
Condyle scanning: each frame is a slice of the distal end of the femur scanning from the medial condyle to the lateral condyle; scanning movie is generated by scanning from the anterior to the posterior of the femur distal end.
Posterior condyle scanning: only the posterior of the distal end of the femur is scanned. Frame scanned from lateral condyle to medial condyle. Movie generated towards the distal end.
Head scanning: the head in the proximal end of the femur is scanned. Each slice corresponds to a movie frame.
parameters: depth resolution: 20um; lateral resolution: 8um; lateral scanning range:3.4mm; frame spacing: 20um
CIA is short for collagenase induced osteoarthritis

PAM1.avi and PAM2.avi are B-Mode images by PAM. The increment between contiguous frames is 10 um. 940 A Lines compose one frame. PAM1.avi is a movie for the first 130 frames and PAM2.avi is a movie for the 131st to 260th frames.
Interpolation of a factor of two is used in the processing of PAM data in both lateral and depth dimension. IIR Buterworth filter is implemented in MATLAB whose cutoff frequency is set to 70 MHz. Hilbert transform is performed before the intensity image is displayed to acquire the analytical representation of the signal.
For one B Mode image of PAM, lateral range: 0.2mm-4.7mm. Depth range: 1.58mm-3.08mm. The dynamic range is -13dB~6dB
SDOCT.avi is a movie generated by B-Mode images of SDOCT. 160 frames are included having an increment between frames of 19.943 um.
The lateral range of the B-Mode SDOCT image is 0.7mm-5.2mm and the depth range shown is 0.1mm-1.8mm. The dynamic range displayed is 58dB~92dB
The photograph of the osteochondral core will be uploaded soon.

Movies of PAM and SDOCT: 1-130th frame of PAM Δ; 131-260th frame of PAM Δ; 160 frame movie of SDOCT Δ
