The description focuses on the physical characteristics and function of an ionization chamber for measuring radiation sources, with no mention of AI or ML technologies.
No
The device is an ionization chamber used for measuring the strength of brachytherapy sources, not for directly treating patients.
No
The device is an ionization chamber intended for the measurement of source strength of brachytherapy sources, not for diagnosing medical conditions in patients. It is used for quality assurance and calibration of therapeutic devices.
No
The device description clearly describes a physical ionization chamber, which is a hardware component used for measuring radiation. It is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to measure the source strength of brachytherapy and intravascular brachytherapy sources. This is a measurement of a physical property (radioactive source strength) used in a therapeutic context (radiation therapy), not a diagnostic test performed on a biological sample from a patient.
- Device Description: The device is an ionization chamber designed to measure radiation. It does not interact with biological samples or perform any diagnostic analysis.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analysis of biological samples (blood, urine, tissue, etc.)
- Diagnosis, monitoring, or prognosis of a disease or condition
- Use in a laboratory setting for diagnostic testing
The device is clearly intended for use in a clinical setting to ensure the correct dosage of radiation is delivered during brachytherapy procedures. This falls under the category of a therapeutic device or a device used in conjunction with a therapeutic procedure, not a diagnostic one.

Intended Use / Indications for Use
The Model 1008 (44D as marketed under CNMC) is a well-type, re-entrant ionization chamber intended for measurement of source strength of both clinical HDR and LDR brachytherapy sources and intravascular brachytherapy (IVB) sources. Both types of IVB sources can be measured; those designed to deliver a gamma dose and those designed to deliver a beta dose. The chamber must be calibrated before any measurement of a clinical source takes place. Source strength calculation must be done with the accompanying calibration certificate from the calibration laboratory. The calibration must be performed by an accredited dosimetry calibration laboratory, with the same source type and isotope that is used clinically. The chamber constancy must be monitored after calibration with a proper Measurement Quality Assurance program in order to validate the chamber calibration over a period of time.

Device Description
The Model 1008 / Model 44D is a well-type re-entrant ionization chamber designed for application with brachytherapy and intravascular brachyterapy source measurement. The chamber is hermetically sealed, there is no air density correction requirement. The fill gas is pure argon at an absolute pressure of 23.5 psi, which provides several distinct benefits. These include enhancing the response at low photon energies from both gamma and Bremsstahlung from beta radiation. higher ion collection efficiency and long term constancy measurements.
The Model 1008/44D is fully guarded into the chamber and is equipped with a 1.5 meter low-noise triaxial signal cable terminated with a triaxial collection electrode inside the chamber. When properly connected to a dosimetry electrometer, the chamber housing will be common to the electrometer housing: the collection electrode will be floating with the guard at the chamber bias potential. Therefore, no shock hazard should exist. However, prudent handling of the connectors and equipment is always recommended whenever there is chamber bias being applied.
