Technology of Direct Conversion Détection

Product catalog summary

Product Overview
SOUL is a premium digital mammography product, notable for being the first of its kind in Asia. It utilizes direct conversion detection technology, which enhances image detection and acquisition speed by preventing charge trapping at the metal interface with selenium.

Detector Technology
The product features a TFT Direct/Electrical Sensor and Electrical Switching system, using Canada Analogic’s Direct Conversion Amorphous Selenium-based Detector (a-Se TFT, 85μm). It offers high-resolution imaging (24 x 30 cm) with superior image quality characterized by high DQE, high MTF, and high contrast.

Key Characteristics

Ergonomic design with an intuitive user interface.
Optimized AEC for lower radiation doses.
High-grade image acquisition with low dose and excellent resolution.
Fast reaction rate and high patient throughput.

Image Processing
SOUL's image processing technology, developed in-house, enhances breast cancer diagnosis accuracy by producing sharp images. This technology is modifiable for customer convenience.

Automatic Exposure Control (AEC)
The AEC system minimizes radiation dose, with a typical dose of 1.4mGy.

X-Ray Tube & Filter
The dual target X-ray tube uses Molybdenum and Aluminum targets with Mo/Al and Mo/Rh filters, reducing dose by up to 50% compared to Mo/Mo configurations. Tungsten is used for clearer imaging.

Performance Metrics

20-second image acquisition time.
100mA High Definition Inverter generator.
Resolution of 85μm.
Shooting angle of ±15°.
Vertical range of gantry from 690mm to 1,590mm, accommodating various patient heights.

Diagnostic Accuracy
SOUL's self-developed image processing software has been clinically validated to improve breast cancer diagnostic accuracy, as demonstrated at the National Seoul University Hospital in Korea.

Additional Features

Accurate breast density assessment.
Smart Compress system reduces pain with controlled compression force.
QC software includes functions like Reject Analysis, Artifact Evaluation, DQE, Flat-field, Uniformity, Linearity, MTF, and SNR.

Market Launch
SOUL was launched internationally in 2015.
