What Is the Difference Between X-ray and C-arm? A Simple Guide for Medical Imaging Beginners

图片
  When people walk into a hospital and see different imaging machines, two names often stand out:   X-ray   and   C-arm . They look different, work differently, and are used for different clinical needs — but many patients still get confused. So, what exactly is the difference between an X-ray machine and a C-arm? Let’s break it down in a simple and easy-to-understand way. 1. What They Are X-ray Machine An X-ray machine uses X-ray radiation to take  static, two-dimensional images  of the body. It’s mainly used in radiology departments for routine exams such as: Chest X-rays Spine and limb imaging Abdominal exams Think of it like taking a “photograph” of the inside of your body. PLX118WF C-arm Machine A C-arm is a  mobile fluoroscopy device  shaped like the letter “C,” allowing it to move flexibly around the patient. It can provide  real-time dynamic imaging , making it ideal for surgeries and interventional procedures: Orthopedic surgeries Pa...

How Orthopedic Surgical Robots Enable Minimally Invasive Procedures

图片
  Minimally invasive surgery has become a major trend in modern orthopedics, driven by the need for safer procedures, faster recovery, and better long-term outcomes.   Orthopedic surgical robots —combining advanced imaging, real-time navigation, and high-precision robotic control—are transforming how surgeons perform complex operations. But how exactly do these systems make minimally invasive surgery possible? 1. Accurate Preoperative Planning Enables Smaller Incisions Before surgery begins, orthopedic robots use 3D imaging such as CT scans to create a detailed model of the patient’s anatomy. This allows surgeons to: Precisely plan the implant position Simulate the surgical path Select the smallest possible surgical approach By knowing the exact bone structure and optimal entry angles in advance, surgeons can avoid large exposures and reduce incision size. 2.  Real-Time Navigation Guides  Precise Instrument Placement During the procedure, the robot works like a “GPS ...

Exploring Mobile DR: The “Moving Robot” in Hospitals

图片
  In hospitals, many people have probably noticed medical staff pushing a mobile “robot” through hallways and wards. Out of curiosity, you may have wondered—what exactly is this machine? What is it used for? What are its advantages and disadvantages? Today, let’s take a closer look at the  mobile DR (Digital Radiography) system . What Is a Mobile DR System? A  mobile DR , or  mobile digital radiography system , is a portable X-ray imaging device that allows radiologic examinations to be performed  directly at the patient’s bedside . Key Advantages of Mobile DR 1. Overcoming Spatial Limitations Mobile DR enables bedside imaging without the need to transfer critically ill patients, reducing the risks associated with patient transport—such as tracheal tube displacement or interference with ECMO (extracorporeal membrane oxygenation) equipment. It is particularly useful in  ICUs, emergency departments, and for postoperative patients  who cannot be moved eas...
