Question

I am trying to understand the programming of Siemens scanner using C++ and given that my C++ skills are limited, I am having problems in understanding many parts of the code provided by the vendor.

Problem 1

For instance, the code uses reference (rMrProt) to object MrProt and notations (such as the use of use of (). and ()[].) are very confusing to me.
For instance:

ImageSamples = rMrProt.kSpace().baseResolution()
ImageSize = rMrProt.sliceSeries()[0].readoutFOV()

Some explanation of these statements would be appreciated.

All information regarding object MrProt are in “MrProt.h”, “MrProt.dll”, “MrProt.lib”. All these files have been shared at:
https://docs.google.com/open?id=0B0Ah9soYnrlIYWZkNDU2M2EtYTNmNC00YTc5LTllMzItYzIyMWU4M2ZhY2Fi

Problem 2

Also, I have been trying to read MrProt.dll and MrProt.lib without any success. Only now, I came to know of dumpbin. Any help would be appreciated.

Problem 3

Another confusion that I have is related to some part of MrProt.h itself. There is a statement in MrProt.h:

class __IMP_EXP MrProt: public MrProtocolData::MrProtDataDelegate
{
   typedef MrProtocolData::MrProtDataDelegate BasicImplementation;
   public:
   MrProt();
   MrProt(const MrProt& rSource);
   …
   ….
}

Here, __IMP_EXP, I guess that it’s some compiler specific stuff.. some decoration etc. But, I still have no idea what to make of this.

Answer 1

Problem 1.

rMrProt.sliceSeries()[0].readoutFOV()

means

• Take rMrProt‘s sliceSeries member and call that. Apparently, it returns an array-like object, something that can be indexed.
• From the result, take the first element ([0]). That’s some kind of object.
• On that element/object, call readoutFOV.

Problem 2. You’re not really supposed to read binary files. There should be documentation with them.
