Advanced SPECT Imaging System with Optimized Photon Transmission

The inventive concept discloses an advanced SPECT imaging system that incorporates a collimator with multi-pinholes having filters to optimize photon transmission rates, resulting in improved image resolution and reduced noise.

The original patent, 'Imaging systems and methods', disclosed a SPECT system with a collimator having multi-pinholes. However, the original patent had limitations in terms of image resolution and noise. The new inventive concept addresses these limitations by introducing filters in the collimator to adjust photon transmission rates, thereby improving image quality.

The advanced SPECT imaging system comprises a detector configured to detect photons and a collimator having at least two sets of pinholes, each set equipped with filters. The filters are configured to adjust photon transmission rates to optimize image resolution and reduce noise. The system can also include a detector with enhanced sensitivity to detect photons transmitted through the collimator. The collimator's pinholes can be dynamically adjustable to optimize photon transmission rates in real-time during imaging. The system can process detected photons to generate high-resolution images with reduced artifacts.

The new inventive concept introduces the use of filters in the collimator to adjust photon transmission rates, which is not disclosed in the original patent. The inventive step lies in the combination of the filters with the multi-pinholes collimator to achieve optimized photon transmission rates, resulting in improved image quality.

Alternative embodiments of the inventive concept may include using different types of filters, such as absorptive or diffractive filters, or varying the arrangement of the pinholes and filters. Additionally, the system could be adapted for use in other imaging modalities, such as PET or CT.

The advanced SPECT imaging system has potential commercial applications in the medical imaging industry, particularly in the diagnosis and treatment of diseases such as cancer and cardiovascular disease. The improved image quality and reduced noise can lead to better patient outcomes and increased market share for companies adopting this technology.
