Creating a 3D graph of many 2D-view surface plots

I have many b-scan of ultrasound (these are surface plots top down view of x,depth with z being the amplitude of echoes for each cross section of the object)

So i want to put together these cross sections so to get a diagram for the whole object and I want to create a 3d view where it only shows the echos within the whole object (so probably by limitting amplitude it shows just so I can see a sort of transparent look into the locations of the largest echoes

Does anyone have any ideas?

Attach the data

Basically, I access data with RawData(1,:,1) for x,y of 1 for example, which is amplitude against time

I take hilbert envelope and then use that for amplitudes, so I first plotted a surface plot of hilbert envelope (z) with every x plotted, and y is the depth (so proportional to time signal a scan of hilbert amplitudes against time from the raw data)

@darovahere is example data of a b scan at one cross section, x y z values which i get a plot for

i just tried to do contour plots along every cross section but i cant sort out the axes because contour is plotted as xy instead of xz which is what i need as depth is z, its so frustrating matlab is a terrible language

Can you please attach small part of the data? I'm using MATLAB online (don't have it on my computer) and can't use 19mb size data

@darova I have attached it in the comment above, I attached matlab.mat it's example of my function bScan(y) at some y value.

Maybe I need to make the data volumetric and do contour slice? I'm not sure how to though, I can get [X,Y,Z] = bScan(y) at some Y distance, but I'm not sure how to make it volumetric for use with contour slice

On using contour, you will get the points/ locations (x,y).... do interp2 and you will get the respective z values......do the same for each surface, and save them and plot.
