From 3aabcd4b6b81e09400c1b959b4f338bc80fc9596 Mon Sep 17 00:00:00 2001 From: jpr Date: Tue, 20 Jun 2006 16:26:08 +0000 Subject: [PATCH] Some more explanations about PMS oddities : Private Sequences are 'Implicit VR', (and their length is *not* 0xffffffff) Readers cannot know it's a Sequence; they just read it as a long value. If we take into account Phillips Intera 'shadow dictionnary', same problem as for MR_Philips_Intera_Broken.dcm occurs again, *for 2 reasons* : endianess is swapped inside Private Sequence 2001|105f, The TS was Implicit VR; it becomes EXPLICIT VR ! gdcm heuristics is broken :-( --- MR_Philips_Intera_No_PrivateSequenceImplicitVR.README.txt | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/MR_Philips_Intera_No_PrivateSequenceImplicitVR.README.txt b/MR_Philips_Intera_No_PrivateSequenceImplicitVR.README.txt index cd0b3a8..8e493a2 100644 --- a/MR_Philips_Intera_No_PrivateSequenceImplicitVR.README.txt +++ b/MR_Philips_Intera_No_PrivateSequenceImplicitVR.README.txt @@ -4,4 +4,9 @@ No more trouble, nowhere !
