Conversion between JAVA Hex and string, and java hexToHexStringPublic static String toHexString (int I) returns the String representation of an integer parameter in the hexadecimal notation.If the parameter is negative, the unsigned integer is 232. Otherwise, the value is equal to the parameter. Convert the value to an ASCII numeric string without leading 0 in hexadecimal notation (base 16. If the value of the unsigned number is zero, it is expressed

()Introduction to using the Mongoose module to manipulate MongoDB modulesMongoose is a module that corresponds to a Nodejs object and a document in MongoDB.The mongoose supports both strong mode and modeless mode.Install Mongoose:$ NPM Install MongooseLet's look at the final directory structure:Configuration and LinksThe format of the link: (You can also omit th

background:The Dicom column introduces the installation and use of the deconstructed PACs (distributed PACs) Orthanc, as well as the analysis of the main modules such as plug-ins and SQLite databases, and introduces the Web Server,mongoose embedded in Orthanc. Relying on Mongoose, this lightweight web Server,orthanc is a good implementation of the RESTful API and traditional DICOM service integration, which

Data model and Base operation templateIn order to make the engineering structure clear, the establishment of data Model (SCHEMA) and the base operation template of adding and deleting and modifying are named as collection in database design (corresponding to the table definition in relational database) and stored in the Models folder.Creation of schema and model:Schema is the data schema in mongoose, which can be understood as the table structure defi

Background:Orthanc is a new DICOM server introduced in this column, with a lightweight, rest-enabled feature that turns any computer running Windows and Linux systems into a dicom server, or Minipacs. Orthanc embedded in a variety of modules, database management is simple, and does not rely on third-party software. So through the analysis of Orthanc source code can learn to build a dicom system in various aspects, such as SQLite embedded database, googlelog Log library, DCMTK Medical Dicom Libra
