    With True2scale Body Scan1, Multitom Rax offers fully-integrated slot scanning: up to two panoramic images in one run, with the patient standing, seated, or even supine. The geometrically accurate images can improve assessment of skeletal malpositioning – at ALADA dose2

    These geometrically accurate, length extended images of the skeletal system in a.p. and lateral plane, are intended to assess skeletal malposition, such as scoliosis or osteoarthritis secondary to malalignment of the limbs.

    Siemens Healthineers Twin Robotic X-Ray Multitom Rax - Fluoroscopy

    Fluoroscopy1 and minor interventions1 belong in every radiology department with an orthopedic focus. 

    Fluoroscopy1 is often used for needle guidance in musculo-skeletal procedures such as arthrography, arthrocentesis, or pain management. Joint injections and interventional spine procedures that do not use image guidance have failure rates of up to 30%, even in large joints like the shoulder.2

    With its fluoroscopic and minor interventional capabilities, Multitom Rax delivers what is needed in advanced musculoskeletal  imaging – barrier-free access to the patient, positioning flexibility, and isocentric RAXorbit movements – also in a table-free configuration with a wireless footswitch.

    Siemens Healthineers Twin Robotic X-Ray Multitom Rax - Precise insights through unique automation

    RAX detector with AEC and ACSS – 
    minimize overexposure and overcollimation

    With its dose-saving RAX detector, Multitom Rax helps you to limit ‘dose and collimation creep’ by automatically evaluating and adjusting exposure levels.

    With AEC and ACSS, the system always provides the 
    right exposure parameters for the examined body region and sets collimator and radiation field size according to the respective organ program and SID. This helps ensure a reproducible, optimum exposure for the body region under examination.

    Low-dose scoliosis SmartOrtho – significantly lower dose due to optimized parameters

    Dedicated pediatric organ programs for different body regions

    For example, by focusing on vertebral alignment instead of bone structure, the new low-dose scoliosis SmartOrtho organ program lets you significantly decrease dose – ideal for follow-up scoliosis exams.

    ALADA dose is particularly crucial for adolescent scoliosis patients, since they are repeatedly exposed to dose.
