This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,168.

Summary of the Inventive Concept

This invention improves upon the original imaging module by incorporating advanced components and techniques to enhance image quality, reduce thermal noise, and provide stable power supply, ultimately leading to better diagnostic and treatment outcomes.

Background and Problem Solved

The original patent disclosed an imaging module for endoscopes and catheters, but it had limitations in terms of image quality, thermal noise, and power supply stability. The new inventive concept addresses these limitations by introducing a light-emitting diode with a specific wavelength range, a temperature control unit, and a power supply unit with noise reduction capabilities.

Detailed Description of the Inventive Concept

The enhanced imaging module comprises a solid-state image sensing device, a light-emitting diode, a temperature control unit, and a power supply unit. The light-emitting diode is configured to emit light in a specific wavelength range to enhance image quality. The temperature control unit maintains a stable temperature of the solid-state image sensing device to reduce thermal noise. The power supply unit provides a stable power supply to the imaging module and the light source, ensuring consistent performance. The imaging module can be configured to capture images at a higher frame rate, and the captured images can be processed using a noise reduction algorithm to further improve image quality.

Novelty and Inventive Step

The new claims introduce the use of a light-emitting diode with a specific wavelength range, a temperature control unit, and a power supply unit with noise reduction capabilities, which are not present in the original patent. These advancements provide a non-obvious improvement over the original imaging module, resulting in enhanced image quality, reduced thermal noise, and stable power supply.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of light sources, such as LEDs or lasers, or incorporating additional components, such as image processing algorithms or data storage units. The imaging module could also be designed to be compatible with different types of endoscopes or catheters.

Potential Commercial Applications and Market

The enhanced imaging module has significant commercial potential in the medical device industry, particularly in the fields of endoscopy and catheterization. The improved image quality, reduced thermal noise, and stable power supply make it an attractive solution for medical professionals seeking to improve diagnostic and treatment outcomes. The target market includes hospitals, clinics, and medical research institutions.
