Abstract: An apparatus, method, and computer program product for calibrating a CT scan without the use of an external calibration phantom, to enable quantitative assessment of internal body tissues and organs and additionally for any application that would benefit from a calibration of the scan attenuation data, such as viewing CT images in a consistent fashion. Embodiments are described with applications to quantitative assessment of bone density in the spine and hip, mineral content in blood vessels, hepatic-fat content in the liver, and gray-to-white matter ratio in the brain. The primary advantages of the method are that it does not require the use of an external calibration phantom, it is robust across different CT machines and scanner settings, and it is also highly precise, lending itself to a high degree of automation.

Abstract: A CMOS image sensor (CIS) device includes an array of pixels, each pixel including a sensing element (e.g., a photodiode) and access circuitry. To facilitate the passage of light to the photodiode, each pixel includes a via wave guide (VWG) defined in the metallization layer formed over the pixel's photodiode. The VWG includes an upper light concentrator having a curved (e.g., parabolic) surface extending from a relatively wide upper opening to a relatively small lower opening. The VWG also includes a lower section extending between the lower opening of the light concentrator and the associated photodiode. A mirror coating is optionally formed on the surface of the VWG. An optional light-guiding material and/or color filter materials are disposed inside the VWG. An optional microlens is formed over the VWG.
