Abstract
Uvod: PACS je v omrežje povezana skupina računalnikov, strežnikov in arhivov, ki se uporabljajo za upravljanje z digitalnimi slikami. RIS upravlja informacije o pacientih, ki se nanašajo na radiologijo, skrbi za naročanja preiskav, zajemanje ustreznih kliničnih informacij in posredovanje teh informacij ostalim sistemom. Odprtokodna programska oprema na tem področju je že dovolj dozorela, da je mogoče vzpostaviti stabilen sistem. Namen: Namen magistrske naloge je bil vzpostaviti odprtokodna strežnika PACS in RIS in z njima povezati ultrazvočno modaliteto ter preveriti ali sistem deluje po standardih DICOM in HL 7. Metode dela: Za izvedbo magistrske naloge smo uporabili odprtokodni arhiv PACS Dcm4chee in odprtokodni RIS Bahmni. Z arhivom smo povezali ultrazvok SonoScape E2 Exp ter odprtokodna pregledovalnika slik Weasis in Horos. Pomembnejšo vlogo pri komunikaciji med gradniki sistema so imeli sporočanje HL 7 ORM in storitvi DICOM MWL in MPPS. Rezultati: Uporabnik implementiranega sistema upravlja sistem samo preko RIS-a Bahmni, kjer izvaja vpis pacienta, naročilo izvedbe preiskave in preklic naročila izvedbe preiskave. RIS mu omogoča tudi vpogled v podatke pacienta in opravljene preiskave. Strežnik PACS Dcm4chee in RIS Bahmni sta integrirana, zato uporabnik ne ve, kateri sistem upravlja s posameznimi procesi. RIS posreduje podatke o preiskavi strežniku Dcm4chee, na katerem se nahaja seznam dela. Ultrazvok ob osvežitvi svojega seznama dela pridobi pripadajoče paciente in preiskava se lahko začne. Na koncu preiskave so slike poslane v arhiv Dcm4chee, pacient pa izgine iz seznama dela. Razprava in zaključek: Vzpostavljeni sistem deluje v skladu s standardoma DICOM in HL 7. Omogoča registracijo pacienta, naročanje preiskav, dostop modalitetam do seznama dela, sledenje izvedenim korakom preiskave, shranjevanje slik v arhiv, dostop do slik s pregledovalniki slik iz oddaljenih lokacij ter pisanje izvidov. V prihodnosti bi bilo dobro takšen ali podoben odprtokoden sistem testirati v kliničnem okolju, da bi videli, kako se obnese ob večjem številu uporabnikov. Potrebno bi še bilo dodelati pisanje izvidov in vzpostaviti obračun storitev.

Title:Implementation of open-source picture archiving and communication system and radiology information system : master thesis
Abstract:
Introduction: PACS is a networked group of computers, servers and archives. It manages digital images. RIS manages patient information related to radiology. It supports examination ordering, capturing relevant clinical information, and communicating that information to other systems. The open-source software in the field of radiology informatics has already matured enough to provide many kinds of stable systems. Purpose: The purpose of the master's thesis was implementation of open-source PACS and RIS servers connected with an ultrasound modality, and testing the system's DICOM and HL 7 compliance. Ultrasound system and image viewers are connected to the PACS server. The PACS server takes care of archiving of images. The RIS performs the tasks of patient registration and examination ordering. The whole system supports carrying out ultrasound examinations and communicates according to DICOM and HL 7 standards. Methods: Open-source Dcm4chee PACS archive and Bahmni RIS have been used to implement the system. The ultrasound system and open-source image viewers have been connected to the archive. HL 7 ORM messaging and DICOM MWL and MPPS services played a key role in establishing the communication between individual systems. Results: A user controls the implemented system through the Bahmni RIS. He can register a new patient and order or cancel an examination. He can also look up patient's data and past examinations. The Dcm4chee and Bahmni are integrated. Consequently the user does not know which system manages each process. The RIS conveys the examination data to the Dcm4chee's modality worklist. The ultrasound system is able to retrieve appropriate patients when refreshing its worklist. At the end of the examination, the images are sent to the Dcm4chee archive and the patient is deleted from the worklist. Discussion and conclusion: The implemented system works in accordance with DICOM and HL 7. It supports patient registration, examination ordering, modality worklist, modality performed procedure steps, image archiving, remotely accessing images and writing reports. In the future, it would be beneficial to test this kind of open-source system in a clinical setting to evaluate its behaviour with many users accessing its resources. It would also be necessary to improve the report writing and implement a billing system.
