How to keep adding rows in a structure inside a for loop

The screenshot below is what I want to accomplish. I have a for loop that, for each organ name, calculates the coverage, maxdose, and meandose. I would like to create an empty structure, then inside the for loop, for each iteration, store the corresponding information in a row, and then adds on to it for the next iteration. How would I do this?

psuedo code:

 create a struct called PatientInfo with fieldnames: 'name', 'coverage', 'maxdose', and 'meandose'
 for i = 1:4
   calculates the corresponding coverage, maxdose & meandose;
   writes these values to a row
 end

Answering my own question

In the loop:

        structrow = structrow + 1;
        PatientInfo(structrow).name = name_val;
        PatientInfo(structrow).coverage = coverage_val;
        PatientInfo(structrow).maxdose = maxdose_val;
        PatientInfo(structrow).meandose = meandose_val;

PatientInfo = struct('name', {'BodyAuto', 'BrainStem', 'SpinalCord', 'Parotid_R'}, 'coverage', [], 'maxdose', [], 'meandose', []);
