How do I extract a decimal value from a 8 byte binary dicom tag?

Hi!

I have a problem with extracting a dicom tag which I know is supposed to contain some form of a decimal value.

When calling dicomdisp the tag in question is displayed as:

0001074 0 (0011,103B) "" 8 bytes - Private_0011_103b *Binary*

When I try

pixelval=metadata.(dicomlookup("0011","103b"))

to extract the value I get the following output:

8×1 uint8 column vector

0

0

0

0

129

167

13

64

So how do I convert this column vector to the associated decimal value? Alternatively, extract the decimal value instantly.

I know this particular decimal number should have the value of "3.7067890167236328".

Thank you!

You will need the typecast function:

typecast(uint8([0 0 0 0 129 167 13 64]),'double')

ans = 3.7068

This will conver the variable to a different datatype without changing the underlying binary data.

Thank you so much for the quick answer! That worked perfectly!
