Innovative CdTe Sensor Technology Direct Conversion X-ray absorption efficiency (typical material thicknesses) Innovative CdTe sensor technology converts X-rays directly to electronic signals. Since X-rays are not converted into light, less blurring occurs and picture clarity and contrast are greatly enhanced.
