Sugestões de compra Rad Room, Digital

  1. Storage space reduction, enhanced image processing, and off-site diagnostic capabilities are some of the advantages of digital rad rooms over film-based radiography.
  2. The tilting tables allow a wide range of tilting movements from -15° to +90° and have an average speed of 6°/sec. Horizontal-to-vertical tilt should average 15 sec.
  3. The non-tilting tables specify a wide range of tabletop motions but do not allow tilting angles.
  4. Digital radiographic table systems generally perform upright examinations or table-based examinations, for which detector mounting is crucial.
  5. The detector is fixed on the digital radiographic table system in table-based units, preventing certain examinations due to patient positioning constraints. Some upright digital radiography systems can be tilted to allow table based exams.
  6. Facilities should evaluate all types of examinations being performed before deciding which type of digital rad rooms will better suit their needs. The number and types of procedures will influence the features selected for the system.
  7. Smaller focal-spot sizes can provide better spatial resolution on film for certain studies, and options such as tomography and table tilt can increase the digital rad room system’s overall procedural capabilities.
  8. Departments handling trauma and emergency cases may prefer elevating tables, because the table height can be adjusted to facilitate patient transfer from a mobile stretcher or a wheelchair.
  9. Bucky systems for both tilting and non-tilting tables should be motorized.
  10. To ensure acceptable film darkening, a three-field AEC device is recommended. Grid ratios should be 10:1 or higher. Grids with higher ratios provide higher image quality.
  11. Buyers of digital radiography should look into the digital rad room system’s integration into picture archiving and communication systems (PACS) already in use in the facility.
  12. Buyers of digital rad rooms should consider generator options as well; high-frequency generators need less space and often eliminate the need for high-voltage cables.
  13. To facilitate future additions to any digital radiography network, compatibility with DICOM 3.0 is a requirement for all newly purchased digital radiography equipment (including storage devices).
  14. Suppliers must provide DICOM conformance statements that explain in detail which information objects, service classes, and data encodings are supported by the system. The statements should be inspected by specialists, and should share the same format and vocabulary to facilitate comparisons between suppliers.
