Digital radiography (DR) is a widely used medical imaging solution with irreplaceable advantages in the examination of chest, abdomen and spine and joints. The current digital radiography equipment can be divided into DR suspension, U-arm flat DR, double column DR and other types according to the DR mechanical structure. What are the advantages and disadvantages of each? Next, let's take a look at their respective advantages and disadvantages.

Suspension DR

Suspension DR

Suspension DR adopts the mechanical structure design of suspension, and the arm of its bulb tube is suspended from the roof.

The advantages of suspended DR: high degree of intelligence, flexible flat ball tube activities, support 360 ° all-round for free and unobstructed position of the film.

Disadvantages of cantilever DR: complex component configuration, high installation environment requirements, high failure rate of cantilever arm motor and travel switch, expensive and high maintenance cost.

U-arm flat panel DR

U-arm flatbed DR

U-arm flat DR mechanical structure similar to the English letter "U", also known as U-arm digital X-ray machine.

The advantages of U-arm flat panel DR: small footprint, low requirements for installation conditions, and relatively cheap price.

Disadvantages of U-arm flat DR: the bulb can not play the angle, limiting part of the clinical application, and is the chest / bed position conversion time is long, in the case of a large number of film, non-stop two position conversion is slightly troublesome.

Double column DR

The design of the structure of the column, the components include x-ray bed, x-ray generator column and detector column.

The advantages of double column DR: compact structure, simple operation, electric assistance for switching between vertical and horizontal positions, small space requirements, easy installation, and few mechanical failures.

Disadvantage of double column DR: the shooting angle of some positions is limited.

The above is a summary of the advantages and disadvantages of suspension DR, U-arm flat DR and double column DR, this information will help us to reasonably purchase DR equipment.

For large general hospitals, suspension DR can meet the needs of filming to the greatest extent.

Double column DR is more often used in scenarios such as medical examination centers, CDCs and medical examination vans.

The U-arm flat panel DR is generally favored by the grassroots hospitals and township health centers, such as the Puai Medical large vision U-arm flat panel DR, its breakthrough 17 * 34-inch dynamic flat panel, to achieve the whole plate shot without splicing; all-electric U-arm frame, with a large range of 170 ° rotation angle, the body is small to fully save space; a machine multi-purpose, to meet the whole body digital photography, digital fluoroscopy, digital imaging and other examination It can meet the needs of whole-body digital photography, digital fluoroscopy, digital imaging, etc. and reduce the investment cost of hospital equipment.
