Overhead Tube Radiography System

The MiiRAD OT is a modern, multi-purpose overhead tube radiography system configured to meet the demands of high-volume diagnostic imaging. With ease of use, image quality, dose reduction, and efficiency, this system offers versatility with excellence and return on investment in terms of total cost of ownership and throughput.

Designed to make examinations easier for staff and patients, the MiiRAD OT comes with intelligent system features for easier positioning and faster exams.  The smooth, easy operation of the tube provides head-to-toe patient coverage and can reach the desired position no matter where your patients are. Located at the tube, the intuitive color touch display allows you to set and change key image paramaters without leaving the patient and saving you time.

Convenient Height Adjustment

The table height adjustment is made by depressing the foot pedal and the safety switch on the operation handle. The table stops automatically in the predefined exposure height. The ability to adjust the table height from 21.2 in (54 cm) to 33.4 in (85 cm) is ideal for easy patient tranfers from a wheelchair or stretcher to the table.

Smooth, Silent Operation

You need only one hand or foot for any adjustment! All movements are perfectly counterbalanced to guarantee smooth and effortless motion. The super silent motor with its electronic control system gives the table a soft start and stop, providing patients little to no sensation of vertical movement.

The vertical bucky travel and tilting movement on the wall-stand is accomplished by depressing the appropriate lever on the bucky carriage. The bucky carriage bearings are plastic clad to provide a smooth silent movement.

Optimal Conditions

The table top and front cover plate of the wall-stand bucky are constructed from low absorption materials for maximum contrast and low radiation dose to the patient.
