Django 简易PACS读片系统
1、Django中写一个后端接口，给HTML提供dicom文件接口的方式
1、首先创建django项目
1、下载安装跨域的包
pip3 install django-cors-headers
2、使用pycharm创建一个Django项目
3、点击创建在另一个窗口，这个都无所谓，怎么都行，就是打开这个项目
4、创建成功的项目就是下面这个样子
5、先修改几个选项，后面好操作
下面是我的settings设置，我把修改的地方标注出来

]# Default primary key field type
# https://docs.djangoproject.com/en/3.2/ref/settings/#default-auto-fieldDEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'6、把表结构映射到数据库中
连接数据库的设置，没有这个设置，数据库会连接失败
import pymysql
pymysql.install_as_MySQLdb()
7、在终端运行两行命令
python manage.py makemigrations
8、运行第二行命令
python manage.py migrate
9、第一步完成，数据库连接成功，基础设置完成
2、写前端页面，并且和后端接口，传递单个dicom文件，并且显示出来
1、先添加一个路由
from django.conf.urls import include
2、然后在pacs中写urls.py里面的内容
from django.urls import pathfrom . import viewsurlpatterns = [path("index/", views.index), # 设置首页内容path("read/", views.read), # 读dicom文件path("read1/", views.read1), # 读dicom文件
]
3、写这个index的方法，在views.py中
from django.shortcuts import render
from django.http import HttpResponse, FileResponse# Create your views here.
def index(request):return render(request, 'index.html')def read(request):file = open('static/dicom/C9214289', 'rb')response = FileResponse(file)response['Content-Type'] = 'application/octet-stream'response['Content-Disposition'] = 'attachment;filename="1.dcm"'return responsedef read1(request):file = open('static/dicom/C9214530', 'rb')response = FileResponse(file)response['Content-Type'] = 'application/octet-stream'response['Content-Disposition'] = 'attachment;filename="2.dcm"'return response
4、写index.html的内容
我写的这个html，直接放进去就可以看，其中的内容你可以通过cornerstone.js查看
pacs
全部都是鼠标左键的操作
5、启动项目
1、第一种，通过pycharm打开
2、第二种，命令行的方式
python manage.py runserver
5、查看网页
其中的功能都可以进行操作，后续我进行优化，默认滚动条是切换dicom
http://127.0.0.1:8000/index/
6、成功
