Safety systems for radiotherapy

PERSONAL SAFETY

Safety in day-to-day operation

Video-based room analysis for prevention of accidental exposure of personnel without additional auxiliary equipment provides uncompromising safety for everybody in the treatment room:

  • continuous monitoring of the treatment room based on three-dimensional video data analysis in real-time, including the machine room
  • protection without additional auxiliary equipment, such as transponders
  • full functionality regardless of movement or markers
  • automated learning algorithms to adapt to changes in the therapy room, including short- and long-term remaining items
  • integration of the controls of the radiation protection door by simple operation via the OPASCA door-terminal

PATIENT VALIDATION

Saftey clearance by way of facial recognition

The OPASCA Workflow Suite offers you a reliable way to automatically verify the patients’ identity – fully integrated into your workflow. An active validation done by the patients themselves avoids mistaken patient identities and generates more safety:

  • seamless integration into the OPASCA safety workflow and your OIS
  • automatic release of the interlock after positive validation
  • logging of individual facial feature according to data protection compliance requirements
  • tracking of physiognomic changes in patients over course of therapy for a
    constant high level of safety

PATIENT SETUP VALIDATION

Excluding error sources

The OPASCA Workflow Suite knows the individual setup for each patient and supports you in the treatment preparation process:

  • visual selection and cross-checking of the correct patient-individual utilization of immobilization devices
  • automated verification of the selected setup against the required setup
  • visual and easily understandable feedback in case of required changes
  • simple reproducibility of the required treatment
  • seamless integration into the OPASCA safety workflow

LOCAL DOSE MEASUREMENT

A quantum more

The reliable measurement of the current dose rate is important to protect patients and comply with statutory requirements. Our local dose rate measurement offers:

  • safe, continuous and reliable in-situ measuring of local dose rates
  • integration of the radiation protection door with acoustic and optical warning
  • continuous archiving of measurement data for long-term evaluations of the weekly, monthly and annual dose rates in the treatment room
  • redundant power supply to secure records also in the case of power failure

GATING FEEDBACK

Safety through collaboration

Especially in the case of deep inspiration breath-hold therapy techniques, the active collaboration on the patient side is of crucial importance. The OPASCA respiratory gating-feedback offers the patient an intuitive feedback – without any additional equipment:

  • feedback to the patient on their breathing curve via colour change of the room lighting
  • light changes clearly discernible for patients in any position, also from the peripheral field of vision
  • significant reduction of treatment time from the first fraction on
  • no necessity for patient coaching due to the intuitive feedback
  • possibility to reduce safety margins of the individual respiratory gate
  • no need for additional devices, e.g. glasses, guarantee a fully hygienic workflow within every treatment
  • fully seamless integration into existing respiratory gating systems

AUDIO-VISUAL MONITORING

Best insights – clear and precise

The direct communication with your patients creates safety and increases convenience for all parties involved. The comprehensive OPASCA communications system facilitates contact during the entire treatment:

  • perfect audio quality by active filtering of background noise
  • detection of patient activity and activation of the intercom mode
  • multifunctional system for communication by means of intercom, announcements, multi-party and group calls

The OPASCA video surveillance system handles the specific requirements of radiation oncology:

  • radiation-hardened cameras for a long operating life above average
  • high quality pictures due to special wide-angle lenses for 100% room coverage
  • high light sensitivity for operation in dimmed rooms
  • additional integration of one-click pan-tilt radiation-hardened cameras with optical zoom
