Type10004 (B-scan Metadata Metadata for a single B-scan.)

Size: 428 bytes

The current Bscan-Meta structure builds on the implementation found in LibE2E.

Offset	Name	Size	Parses to	Description
0	unknown0	4	int
4	size_y	4	int	Bscan height
8	size_x	4	int	Bscan width
12	start_x	4	float	Start X coordinate of Bscan
16	start_y	4	float	Start Y coordinate of Bscan
20	end_x	4	float	End X coordinate of Bscan
24	end_y	4	float	End Y coordinate of Bscan
28	zero1	4	int
32	unknown1	4	float
36	scale_y	4	float	Scale of Bscan y-axis (height)
40	unknown2	4	float
44	zero2	4	int
48	unknown3	8	List[float]
56	zero3	4	int
60	imgSizeWidth	4	int	This might differ from size_x, the actual meaning of this value is unclear, maybe you can compute the x-axis scale from this value.
64	n_bscans	4	int	Number of Bscans in the respective volume
68	aktImage	4	int	Index of the current Bscan in the volume
72	scan_pattern	4	int	Scan pattern of the volume. Does this corresponds to the scan pattterns in VOL and XML export?
76	center_x	4	float	Exactly the average of start_x and end_x.
80	center_y	4	float	Exactly the average of start_y and end_y.
84	unknown4	4	int	Maybe the UTC bias?
88	acquisitionTime	8	int	Acquisition time of Bscan
96	numAve	4	int	Number of averages according to LibE2E Not coherent with XML export
100	quality	4	float	Quality according to LibE2E Does not match the quality value in the XML export which is an integer compared to a float here with value 0.84 for a complete volume. Maybe this is the focus length, at least it is similar to the value given in the XML (0.87)
104	scale_x	4	float	Scale of Bscan x-axis (width)
