How to Forward most recent Prior

Conquest v.1417d

Hi,

I need to figure out how to forward the most recent prior for a patient when a new study has arrived. For example, when a study arrives with a study description of 'MR Brain' I need to forward that patients most recent 'MR Brain' to a specific remote AE Title. Is this possible?

thanks

Marcel,

in your code below:

q = {}
q.PatientID = Data.PatientID
q.StudyDescription = Data.StudyDescription
q.StudyDate = ""
q.QueryRetrieveLevel = 'STUDY'
r = dicomquery('CONQUESTSRV1', 'STUDY', q)
s={}
for i=1, #r do
  s[i].StudyDate = r[i-1].StudyDate
  s[i].StudyInstanceUID = r[i-1].StudyInstanceUID
end
table.sort(s, function(a,b) return a.StudyDate > b.StudyDate) end)
script("forward patient study ".. s[1].StudyInstanceUID .. "to AE")

does it watch incoming studies? How would I modify the script to look for 'MR Brains' only?

Marcel,

wouldn't '~=' mean that it 'does not equal'. I would actually need '==' right?

REPLY: you need to stop processing for all you do not want.

Marcel,

On this line:

'script("forward patient study ".. s[1].StudyInstanceUID .. "to AE")'

if I wanted the study to go to 'SERVER1' would it look like:

script("forward patient study ".. s[1].StudyInstanceUID .. "to SERVER1")

OR

script("forward patient study ".. s[1].StudyInstanceUID .. "SERVER1")

thanks

REPLY: "to SERVER1"

Marcel,

running the code below:

-- 1.4.17d
q = {}
q.PatientID = Data.PatientID
q.StudyDescription = Data.StudyDescription
q.studydate = ''
q.QueryRetrieveLevel = 'STUDY'
q.StudyInstanceUID = ''
r = dicomquery('RADARCH4', 'STUDY', q)
s={}
for i=1, #r do
  if string.find(r[i].StudyDescription, '*brain*') then
     return
  end
   s[i].StudyDate = r[i-1].StudyDate
   s[i].StudyInstanceUID = r[i-1].StudyInstanceUID

end
table.sort(s, function(a,b) return a.StudyDate > b.StudyDate end)
script("forward patient study ".. s[1].StudyInstanceUID .. "to SERVER1")

and it comes back with '...:10: attempt to get length of global 'r' (a nill value)'

this is after I had sent it a 'MR Brain' study waiting for it to forward me the recent 'MR Brain' from this example patient. There is a prior 'MR Brain' for this patient, as I have verified this.

thanks

Marcel,

Yes, its actually the conquest server. I can use different applications to query, push, & pull studies from it right now.

I can run this:

q = newdicomobject()
q.PatientID = ''
q.StudyInstanceUID = ''
q.StudyDescription = '*MR BRAIN*'
q.StudyDate = '20140604'
q.QueryRetrieveLevel = 'STUDY'
r = dicomquery('RADARCH4', 'STUDY', q)
print('found', #r, 'studies')

that comes back with '4' results for today.

Marcel,

I've corrected the capitalization error, but it is still complaining about line 10 '...lua:10: attempt to get length of global 'r' (a nil value)' error message

also added a space for line 9 before and after the '='

here is the code now:

-- 1.4.17d
q = {}
q.PatientID = Data.PatientID
q.StudyDescription = Data.StudyDescription
q.StudyDate = ''
q.QueryRetrieveLevel = 'STUDY'
q.StudyInstanceUID = ''
r = dicomquery('RADARCH4', 'STUDY', q)
s = {}
for i=1, #r do
  if string.find(r[i].StudyDescription, '*brain*') then
     return
  end
   s[i].StudyDate = r[i-1].StudyDate
   s[i].StudyInstanceUID = r[i-1].StudyInstanceUID

end
table.sort(s, function(a,b) return a.StudyDate > b.StudyDate end)
script("forward patient study ".. s[1].StudyInstanceUID .. "to SERVER1")

Marcel,

-thanks for fixing that. The script doesn't error anymore, but nothing gets forwarded to me

I even changed what I was looking for in the 'StudyDescription' to '*brain*'. Is the "to SERVER1" correct in the code below? It IS in the 'acrnema.map' file.

-- 1.4.17d
if string.find(Data.StudyDescription, '*brain*') then
  q = DicomObject:new()
  q.PatientID = Data.PatientID
  q.StudyDescription = '*brain*'
  q.StudyDate = ''
  q.QueryRetrieveLevel = 'STUDY'
  q.StudyInstanceUID = ''
  r = dicomquery('RADARCH4', 'STUDY', q)
  s = {}
    for i=1, #r do
      s[i] = {}
      s[i].StudyDate = r[i-1].StudyDate
      s[i].StudyInstanceUID = r[i-1].StudyInstanceUID
    end
table.sort(s, function(a,b) return a.StudyDate > b.StudyDate end)
script("forward patient study ".. s[1].StudyInstanceUID .. "to SERVER1") 
end

Marcel,

I've told it to print as you suggested above, but nothing shows up in my 'serverstatus.log'. I"m running an old copy of 'dicom.ini' from before the v1.4.16 days. Could there be a setting in the .ini I'm missing since v1.14.17d?

thanks

Marcel,

now it isn't printing anything, do I have to wait for 5 min?

On line 13, there is a print function

-- 1.4.17d
if string.find(Data.StudyDescription, '*brain*') then
  q = DicomObject:new()
  q.PatientID = Data.PatientID
  q.StudyDescription = '*brain*'
  q.StudyDate = ''
  q.QueryRetrieveLevel = 'STUDY'
  q.StudyInstanceUID = ''
  q.ModalitiesInStudy = '*MR*'
  r = dicomquery('RADARCH4', 'STUDY', q)
  s = {}
    for i=1, #r do
      print('found', #r, 'priors')
      s[i] = {}
      s[i].StudyDate = r[i-1].StudyDate
      s[i].StudyInstanceUID = r[i-1].StudyInstanceUID
    end
table.sort(s, function(a,b) return a.StudyDate > b.StudyDate end)
print("forward patient study ".. s[1].StudyInstanceUID .. "to SERVER1") 
end

Marcel,

I'm guessing that the 'If' statement isn't working. I've created another basic script to just print something and I have called it in the dicom.ini file as:

ImportConverter0 = print.lua

Here is the code:

if string.find(Data.StudyDescription, 'brain') then
  print ("Is this what you are looking for?--", Data.StudyDescription)
end

This should print out 'MR Brain w+wo Contrast' when it receives a study with the word 'brain' in the study description.

this will not print anything in the 'serverstatus.log' file.

correct me if I'm wrong, but this 'if string.find' will only work on incoming images correct?

thanks
