20 ; Query/Retrieve
21 ;
22 ; Step 1: The application (Java system) receives a C-FIND request
23 ;
24 ; Step 2: The application interprets the DICOM message and
25 ; calls an RPC on traditional VistA
26 ;
27 ; RPC name: MAG CFIND QUERY
28 ; input: array of: tag | VR | flag | value
29 ; input: scalar: batch-identifier, see below
30 ; input: scalar: max # entities in response
31 ; output: array of: header = # entities total | # in current batch
32 ; followed by tag | VR | flag | value
33 ; or <start sequence>
34 ; or <end sequence>
35 ;
36 ; Batch-identifier:
37 ; There are four kinds of calls:
38 ; 1. initial call
39 ; value of this parameter is "0"
40 ; RPC will create result-set and start a background process to
41 ; perform the query
42 ; 2. "are you ready" call
43 ; value of this parameter is "n|0"
44 ; where 'n' identifies the result-set
45 ; RPC will check if the query is ready and, when available, will
46 ; return "initial batch" of responses
47 ; 3. continuation call
48 ; value of this parameter is "n|m"
49 ; where 'n' identifies the result-set
50 ; where 'm' identifies the sequence
51 ; number of the first item to be returned RPC will return
52 ; next batch of responses
53 ; 4. final call
54 ; value of this parameter is "n|-1"
55 ; where 'n' identifies the result-set
56 ; RPC will not return any responses but clean-up any storage used
57 ; for result-set
58 ;
59 ; Suggested values for second parameter:
60 ; 0 for initial call
61 ; -1 for final call
62 ; >0 (sequence number of first entity to be returned)
63 ; for continuation call
64 ; Result-set will also have a "time stamp of last access"
65 ; so that an overall clean-up process can get rid of
66 ; obsolete result-sets.
67 ;
68 ; Step 3: The application interprets the results from the RPC
69 ; and will ask VistA which images belong to a
70 ; study-UID:
71 ;
72 ; RPC name: MAG STUDY UID QUERY
73 ; input: scalar study uid
74 ; input: scalar flag: include routed copies in result
75 ; input: scalar "my location" identifier
76 ; output: array of: header = # of entities in response
77 ; image# | path+file name | username | password
78 ;
79 ; Do we want to return the username and password in each
80 ; result, or do we want two separate RPC calls: one to
81 ; get path+filename for each file, and one that returns
82 ; the username and password given a path?
83 ;
84 ; Step 4: The application will create new DICOM entities to transmit
85 ; to its client. It has the information to access the
86 ; image files that exist on VistA (either .dcm files or
87 ; .txt + .tga pairs). It needs to ask VistA for the
88 ; current and correct information to place in the headers
89 ; of the DICOM entities to be transmitted:
90 ;
91 ; RPC name: MAG IMAGE CURRENT INFO
92 ; input: scalar image #
93 ; output: array of: header = # of entities in response
94 ; tag | VS | flag | value
95 ;
96 ; Do we need an additional input array to specify the
97 ; list of data-fields to be returned?
