========================================================================== EXPERIMENTAL DATA ========================================================================== The folder "Ultra_A" contains experimental Full Matrix Capture files for Sample A and "Ultra_B" for Sample B. The file format (MFMC) is described in the PDF. Integer location in the filename can be converted to millimetres by multiplying by 0.0125. Micrograph images of the defect region of Sample A are located in Micrograph_A and the raw XRay data is located in XRay_A. Ultra_A: Contains 84 FMC datasets Ultra_B: Contains 3818 FMC datasets (2 datasets for each position) Multiple datasets are present in each MFMC file (one for each Y sweep) Micrograph_A: 21 JPEG Files, each slice is numbered consecutively (B-1 through B-21) and are 4mm apart (in out of plane direction) XRay_A: 181 BITMAP Files, each slice is numbered consecutively (001 through 181) and are 0.5mm apart (in out of plane direction) For Sample A, position y =-200 (-2.5mm) was utilised as a defect-free dataset for the purpose of noise parameter quantification (Table II). Figures 3 and 6 were sourced from y=1720 (21.5mm) Table III and Figure 7 utilised the Ultrasonic, Micrograph and X-Ray data in Ultra_A, Micrograph_A and XRay_A. For Sample B, 2 ultrasonic FMC datasets were captured at each position. One with a receiver gain suitable to avoid over-saturating the frontwall reflection and a second with a higher receiver gain for interior imaging. The lower receiver gain datasets were utilised to generate the front surface and the higher gain files for the back surface of the sample (Figures 9 and 10). Figure 11 was obtained from y=-4560. Tables V, VI and Figures 12 and 13 were obtained using the x = 400 traverse, with Figure 13(a) located at y = -4560, 13(b) at y = -10680 and 13(c) at y = -16080. ******** FILE FORMAT ******** Refer to the MFMC PDF document. This file format uses the HDF5 (Hierachical Data Format, v5) as a portable scientific data format. ========================================================================== FORWARD MODEL DATA ========================================================================== The folders "Model_A" and "Model_B" contain the derived data. This includes the sensitivity maps and non-uniform surface information (for Sample B) File: derived_data.h5 ******** FILE FORMAT ******** The HDF5 file contains H5 Group (refered to as structure below) and H5 Dataset. The .h5 file contains a single structured variable "derived_data" with fields as follows: xVector: zVector: sens_maps: surfaces: surfaces.curved_fw: surfaces.curved_fw.nfrontwall: < Number of points in surface cloud> surfaces.curved_fw.coordX: < X coordinates of these points> surfaces.curved_fw.coordZ: < Z coordinates of these points> surfaces.curved_fw.coordY: < Y coordinates of these points, IS SINGULAR IF NON-CHANGING (2D)> surfaces.curved_bw: surfaces.curved_bw.nbackwall: < Number of points in surface cloud> surfaces.curved_bw.coordX: < X coordinates of these points> surfaces.curved_bw.coordZ: < Z coordinates of these points> surfaces.curved_bw.coordY: < Y coordinates of these points, IS SINGULAR IF NON-CHANGING (2D)> Notes: "derived_data.sens_maps" is is arranged as a four dimensional array [2,NZ,NX,NView] (left index changing first) Where NX=length(xVector), NZ=length(zVector). The first index (2) is the real (1st value) and imaginary (2nd value) components for the pixel The image grid of size (NZ,NX) has the Z coordinate varying first (stored in consecutive memory). Data on the NView=21 unique TFM views is stored. The view order can be obtained from Fig 3, reading left to right then top to bottom in turn.
