摘要:
過去許多醫(yī)院內(nèi)所產(chǎn)生的醫(yī)療資訊，例如病歷或是醫(yī)療影像，都無法很順利的互相交流傳遞
。這是因?yàn)檫@些醫(yī)療資訊的格式皆不同，各廠牌有各廠牌特有的格式。隨著時(shí)代進(jìn)步，這些
醫(yī)療資訊交流的的需求也愈來愈頻繁，因此就有一些標(biāo)準(zhǔn)格式的出現(xiàn)。對(duì)病歷等文字類的醫(yī)
療資訊是由HL7(Health Level 7)統(tǒng)一格式。對(duì)影像類的醫(yī)療資訊則由DICOM(Digital Image and
Communication
in Medicine)為其標(biāo)準(zhǔn)。本研究主要針對(duì)目前實(shí)用但其輸出的影像並不是DICOM標(biāo)準(zhǔn)格式的造影儀
器，設(shè)計(jì)－轉(zhuǎn)換介面。利用此轉(zhuǎn)換介面，使非DICOM標(biāo)準(zhǔn)格式的影像轉(zhuǎn)換成標(biāo)準(zhǔn)格式。本研究
所採用的造影儀器是正子放射斷層掃描儀(Positron Emission Tomography，PET)及雷射掃片機(jī)。本轉(zhuǎn)換
介面的功能除可轉(zhuǎn)換格式之外，還可以連接至PET工作平臺(tái)，取回影像檔案，連接到病人資料
庫，查詢病人基本資料，並可以將轉(zhuǎn)換後的DICOM檔案?jìng)髦罝ICOM伺服器中。除了轉(zhuǎn)換介面之外
，本研究也對(duì)影像檔案的檔頭加以研究。本研究制定的檔頭可以適合現(xiàn)行PET以及雷射掃片機(jī)
儀器，在轉(zhuǎn)換後的檔案可以保有原有檔案資訊讓影像不失真。本研究的轉(zhuǎn)換介面及影像檔頭
能應(yīng)用到實(shí)際造影儀器上，使得照影儀器所輸出的檔案可以與其它部門或是醫(yī)院交流，讓儀
器可以與醫(yī)院的影像系統(tǒng)結(jié)合，以利醫(yī)療資的整合。
Abstract:
Most medical informatics in hospitals, such as patients' records and medical images, are not easy to
exchange due to the different formats of these medical informatics. Recently, the practice of the information
exchange is becoming more and more popular. In order to provide these services, HL7 (Health Level 7) for
patient records and DICOM (Digital Image and Communication in Medicine) standard for medical images
are proposed. In this research, a DICOM getaway was designed for a medical modality with non-DICOM
output. We used this gateway to convert images with non-standard format to images with DICOM format.
The modalities used were PET (Positron Emission Tomography) and laser scanner. The function of the
gateway includes the connection to PET work platform, getting the image files, connection to patient
database, query/retrieve the patient basic information and transferring the DICOM files to DICOM server.
The headers of image files for PET image and digitized X-ray image were also discussed. The method
developed can be used in the real modality workflow. The paper gives the preliminary results obtained
through the trials in the hospital.
