4D figure with a colormap

Hi!

I have an exercise where I have a certain dicom collection input and from there I have to get only 1 of the series (corresponding to the ones that have 'US' as a Modality in the table) and do the following:

• read the series data with the color map
• display in 1 figure the montage of the series with the color map

Can someone please help me in how should I do this?

The begin of the code will be something like this: (my problem is that I get an 4-D uint8 type of variable and I cannot show it as a regular image)

dir = fullfile( matlabroot, 'toolbox/images/imdata'); %Directory from where I get the dicom Collectuon
infoTable = dicomCollection(dir);

disp(infoTable)

T2 = strcmp(infoTable.Modality,'US'); %Finds the series with the Modality equal to ’US’
series = infoTable(T2,:); %Series with the modality equal to 'US'

fileName = series.Filenames; %Cell array with the file name
fName = fileName{1,1};       %String with the file name

I2 = dicomread(fName); 

Thank you a lot in advance, this is the only information I have (I'm not even telled to use a specific colormap).

Well, dicomCollection() won't run in-browser, but see if this is what you're after:

dir = fullfile( matlabroot, 'toolbox/images/imdata'); %Directory from where I get the dicom Collectuon
infoTable = dicomCollection(dir);

disp(infoTable)

T2 = strcmp(infoTable.Modality,'US'); %Finds the series with the Modality equal to ’US’
series = infoTable(T2,:); %Series with the modality equal to 'US'

fileName = series.Filenames; %Cell array with the file name
fName = fileName{1,1};       %String with the file name

[I2 map] = dicomread(fName); 

montage(I2,map,'size',[5 2])

Yes it was precisely that!! Thank you a lot! :)
