The X-RAD Biological Irradiator is a sophisticated system designed for precise and controlled X-ray irradiation in biological research. It features a robust radiation enclosure, a touchscreen user interface, and various accessories to enhance its capabilities for diverse experimental needs.
The primary function of the X-RAD Biological Irradiator is to produce controlled X-ray radiation for biological specimens. It allows users to manipulate X-ray parameters (kV and mA), run time-dependent or dose-dependent programs, and review exposure histories. The system is designed to provide accurate and consistent exposures, crucial for reproducible research. Safety is paramount, with multiple interlocks and warning systems to prevent accidental radiation exposure.
Radiation Protection: The irradiation cabinet is a one-piece radiation enclosure manufactured to comply with Federal Regulations CFR1020.40, providing radiation protection with a leakage of less than 0.2mRem/hr at any point on the outside surface.
System Control: The system is controlled via a TouchRAD Panel, which includes analog controls/indicators and a touchscreen computer. The System Key-Switch allows changing the system state between OFF, STANDBY, and ON. An Emergency Stop button instantly halts X-ray production when activated.
X-Ray Parameters: The system allows manipulation of kV and mA settings. Exposure times can be set from a minimum of 5 seconds to a maximum of 99,999 seconds in Time Mode. For Dose Mode, exposures end when a pre-defined dose (in cGy) is reached.
Safety Interlocks: All X-RAD Biological Irradiators are equipped with safety interlocks on the cabinet door and baffle. These interlocks prevent X-ray production if disabled and immediately shut off X-rays if activated during an exposure. A CDRH Switch on the cabinet door physically inhibits X-rays from being produced while the door is open.
Warning Lamp: An "X-Ray On" warning lamp provides visual notification when X-rays are being produced. If the warning lamp fails, X-rays will shut off, and an error will be displayed.
Baffle: The baffle provides lead shielding around the port hole(s) to limit irradiation leakage. Some models feature dedicated user-accessible baffles for running wires, cables, hoses, and equipment into the cabinet without radiation leakage.
Dose Measurement Control (PN 150010) (Optional): This option allows users to specify the actual dose (in Gy) to be delivered and terminates exposure when the dose is reached. It uses a PTW 7862 parallel plate transmission chamber to measure relative dose.
X-Ray Beam Conditioning/Hardening Filters with Filter Recognition (Optional): These filters remove undesired low-energy photons, preventing superficial tissue irritation/burns and delivering only desired photons to the specimen. The system automatically recognizes the inserted filter and displays an error if the wrong filter is used.
Fixed Collimators (Optional): Standard or customized fixed aperture collimators define the irradiation field, with sizes ranging from 0.5cm to 10cm diameter. Specialized shapes are available for specific irradiation needs.
Adjustable Collimator (Optional): A motorized 4-leaf X-ray field diaphragm allows users to define rectangular or square exposure fields from less than 1x1 cm to 20x20 cm at 50 cm FSD.
Motorized Shelf (PN XD1602001) (Optional): A key-operated stainless steel specimen shelf allows manual adjustment of the source-to-specimen distance (SSD) via a Shelf Key-Switch. A scale behind the shelf aids in accurate positioning.
Programmable Shelf (PN XD1602201) (Optional): Similar to the motorized shelf, this option allows automatic setting of SSD and specimen offset through the User Interface for each program. It can also be manually positioned via the Shelf Key-Switch. SSD values are in centimeters and must be whole numbers, not accounting for specimen height (offset must be entered separately).
Turntable (Optional): A motorized turntable ensures uniform irradiation of specimens.
Remote Access (Optional): Allows Precision X-Ray to remotely connect for system diagnostics, updates, and troubleshooting, reducing the need for on-site service calls.
Cabinet Heater (PN XD1608401) (Optional): A wall-mounted, thermostatically controlled ceramic heating unit can heat the irradiation chamber up to 35°C.
Environmental Chamber (PN XD1608101) (Optional): Designed for introducing and controlling gases in an environmental chamber. Features include a CO2 controller and sensor, pressure relief valve, two sensors with three access ports, circulation fan, two gas inlets, pullout sliding shelves, and a humidification tray.
Environmental Chamber Temperature Control (PN XD1608101) (Optional): An additional option for the environmental chamber, allowing thermostatic adjustment of the chamber temperature via an electrically heated floor/base.
Pie Cage (PN XD1905005) (Optional): A circular mouse pie cage designed for whole-body irradiation, capable of holding 11 mice. It has a notched ventilated lid for easy insertion and removal of mice.
Mouse Fixtures/Shields (Optional): Lead-shielded mouse restraining fixtures for various partial body irradiation applications (flank, spine, abdomen, head).
User Interface: The TouchRAD User Interface is a touchscreen-based application controlling all X-RAD system functionalities, including running exposures, setting exposure routines, and administering user accounts.
System Startup: The system starts by positioning the System Key-Switch to STANDBY or ON. The computer automatically boots, and the TouchRAD User Interface loads after initialization (approx. 10 seconds).
Logging In: Users must log in to access system functionalities. The Login Screen requires a username and password, which can be entered via an onscreen keyboard or selected from a dropdown list.
Manual Mode (Program 0): Allows users to run exposures without a predefined program, manipulating kV, mA, and exposure time as needed. Users must confirm filter and SSD settings before starting X-rays.
Program Types:
Program Recall: Allows users to select and run pre-defined exposure programs for consistent results.
Warm-up/Conditioning: The system automatically determines if an X-ray tube warm-up is required (if no X-rays have been produced within 8 hours). Warm-up ensures the tube is ready for maximum kV and mA production and prevents damage. Exposures cannot be performed until warm-up is complete (typically 20 minutes for 8-96 hours downtime). Weekly warm-ups are highly recommended regardless of usage.
Specimen Observation Camera (Optional): A closed-circuit live feed camera inside the cabinet allows users to monitor specimens before, during, and after an exposure. Crucial X-ray data and an "X-RAYS STOP" button are displayed on the screen.
Error Handling: The system displays error messages for safety circuit issues or X-ray system malfunctions. Users must fix the error and then clear it using the "CLEAR" button before producing X-rays.
Daily Inspection: Operators should perform daily visual inspections before use:
Annual Maintenance: Performed by an authorized Precision X-Ray Engineer to ensure long-term product reliability and performance. The TouchRAD console displays a message when annual maintenance is due. Services include:
