簡介
紀錄一下以前 Raccoon 新增 ICC Profiles 功能時所遇到的坑。
因 Raccoon 是使用 Node.js 編寫的，所以當時找了處理影像的套件 sharp 套用 ICC Profile，結果發現套用後，與其他 PACS 的顏色不同，並且還發生了一點小插曲！？
以下將使用一些工具展示套用 ICC Profile 的結果。
方法
- 採用 dcm4che 所提供的 ICC Profiles: Github
使用影像內建的 ICC Profile 測試image.raw.icc1769.0KB
- 使用 dcm4che dcm2jpg, nodejs sharp, imagemagick 對影像套用 ICC Profile
- 使用 GIMP 主觀驗證兩者轉出來的顏色
- 使用檔案: ftp://medical.nema.org/medical/dicom/Datasets/WG26/WG26Demo2020_PV/Diagnostics^Roche^Tissue [0010]/20200731 104639 [Steiner 40x z1 Q]/Series 001 [SM]/2.16.840.1.113995.3.110.3.0.10118.2000002.862753.6.dcm

🚫
這邊只是稍微紀錄，sharp 在套用影像內建的 ICC Profile 時跳出 Error: icc_transform: no output profile 的錯誤
使用的程式碼
const sharp = require("sharp");
(async() => {
await sharp("2.16.840.1.113995.3.110.3.0.10118.2000002.862753.6.jpg")

dcm4che 預設轉圖顏色不一致
如果您使用了以下預設的指令將圖轉出來
dcm2jpg 2.16.840.1.113995.3.110.3.0.10118.2000002.862753.6.dcm ^
2.16.840.1.113995.3.110.3.0.10118.2000002.862753.6.jpg ^
--frame 78您會發現，轉出來的圖與 weasis 顯示的圖，顏色明顯不同
此時加入 ICC Profile: No 就會與使用 weasis 觀看到的影像顏色相同
dcm2jpg 2.16.840.1.113995.3.110.3.0.10118.2000002.862753.6.dcm ^
2.16.840.1.113995.3.110.3.0.10118.2000002.862753.6.jpg ^
--frame 78 --icc-profile no這是因為 dcm4che 預設會將原本的影像轉換成 sRGB，並且會自動把 YBR 的影像也都轉換成 RGB，所以在套用 sRGB 時，影像未與其他工具套用 sRGB 的結果不同，是否該預設轉 RGB，目前筆者沒有答案
By default, include no ICC profile, but
transform original pixels to sRGB color
space if an ICC Profile is specified in the
DICOM image.
