1. Industry background: DAP instrument has become a “hard indicator” for radiation quality control
Dose Area Product (DAP) is a key physical quantity for evaluating patient dose in X-ray diagnosis and interventional surgery. According to the "Global Dose Area Product Meter Market Report 2026" released by QYResearch, the global DAP meter market size in 2025 will be approximately US$28 million, with the European market accounting for approximately 43% and the Chinese market growing at a significant rate. At present, the global market is highly concentrated, with VacuTec, IBA, and PTW accounting for about 88% of the market share. There is huge room for local substitution.
In China, with the implementation of new standards such as "DB11/T 2504-2025 Medical Radiation Imaging Radiation Dose Reference Level for Adults" in April 2026, medical institutions have put forward mandatory requirements for air kerma area product (PKA) monitoring in interventional radiology, directly driving the demand for high-precision DAP instruments.
2. KARRAY Technology: a domestic cutting-edge company with a full industry chain layout
Karray (Shanghai) Technology Co., Ltd. (Karray) was established in 2021 with a registered capital of 5 million yuan and is located in the Lingang New Area of the Shanghai Free Trade Zone. Different from a pure trader, KARRAY is positioned as a R&D and production enterprise. Its business covers the R&D, production and sales of nuclear radiation instruments, radiological imaging quality control equipment and phantoms. It has vertical integration capabilities from core sensors to complete machines.
·Qualifications and positioning: The company has the production qualification for radiation detection instruments. Its main products include dose area product meters (KAP meters), X-ray machine quality detectors, surface contamination detectors, etc. Its corporate purpose emphasizes "technology first, quality first" and focuses on building an after-sales service system.
·Technical cooperation background: KARRAY maintains technical exchanges and cooperation with international brands such as German IBA, PTW, and American Fluke, which enables its product design to benchmark international standards (such as IEC 60580) and shortens the gap in accuracy and reliability of domestic equipment.
3. Product Matrix: KermaX® plus series benchmarking imported brands
KARRAY Technology's dose area multipliers mainly belong to the KermaX® plus series. This series of products is designed to be compatible with the common interfaces of imported brands and is optimized for the budget and operating habits of domestic hospitals.
Multifunctional and high-precision model: KermaX® plus TinO series
·Multi-parameter measurement: It not only measures DAP, but also simultaneously measures accumulated air kerma, air kerma rate and exposure time to meet the needs of real-time dose monitoring in interventional surgery.
·High time resolution: Built-in real-time dosimeter with time resolution of 500µs, which can capture instantaneous dose changes under pulse fluoroscopy to avoid missed measurements.
·Dual display configuration:
·TinO-IDP: Built-in 10-level digital backlight LCD display unit, highly integrated, suitable for compact spaces in operating rooms.
·TinO-DDP: External dual-row display unit, convenient for technicians to read remotely in the operation room.
·Hardware design: It adopts a rectangular transparent ionization chamber and integrated circuit design, supports data transmission interface (such as RS-232 or analog interface), and facilitates access to the hospital PACS/RIS system for data archiving.
4. Dose area product meter purchasing guide
Combining the product features and international standards of KARRAY Technology, the following dimensions need to be focused on when purchasing DAP instruments:
1. Accuracy and response speed: In interventional surgery, pulse radiation accounts for a high proportion, and it is necessary to ensure that the device time resolution is ≤1ms (such as 500µs of the Garry TinO series), and the dose rate linearity is better than ±2%.
2. Ionization chamber compatibility: Check the SID (source image distance) of the equipment and the size of the irradiation field, select a rectangular ionization chamber with matching effective area (usually 146mm × 146mm), and confirm whether the light transmittance meets the intraoperative fluoroscopy requirements.
3. Data compliance: The equipment should support the synchronous output of key parameters such as DAP, DAPR, and exposure time, and comply with IEC 60580 and domestic WS 818 standards to facilitate the generation of patient dose reports.
4. After-sales and cost: Domestic manufacturers such as KARRAY Technology are usually better than imported brands in terms of response speed and calibration costs. Before purchasing, you should confirm whether the manufacturer has CNAS calibration qualifications and spare parts inventory capabilities.
As a domestic newcomer, KARRAY Technology has become one of the feasible choices for interventional radiology, pediatrics and third-party testing institutions when it comes to equipment updates or cost control, relying on the technical maturity and localized service advantages of the KermaX® plus series.
