Embodiment Construction

[0026] Figure 1-10 For multimodal compatible Compton cameras. Modular design to form a Compton camera for use with various other imaging modalities or as a stand-alone Compton-based medical imager. Figure 11-18 For adaptive Compton cameras. use Figure 1-10 With a modular design or another Compton camera (e.g., non-modular), one or both of the scattering and detector layers can be moved relative to the patient for control of image quality, sensitivity, and / or other features for improved diagnosis. After summarizing the adaptive Compton camera embodiment, describe Figure 1-9 Compton camera. Figure 1-9 Many features and components of the Compton camera can be used later in the Figure 11-18 The adaptive Compton camera embodiment described in .

[0027] For an adaptive Compton camera, the scatter layer and / or the catcher layer can move towards and away from the imaged object. The scattering layer can be positioned as close as possible to the imaging object, while the ...

Abstract

To optimize image quality and/or sensitivity, a Compton camera is adaptable. The scatter and/or catcher detectors (12, 13) may move closer to and/or further away from a patient and/or each other. Thisadaptation allows a balancing of image quality and sensitivity by altering the geometry.

Description

Background technique [0001] This embodiment relates to medical imaging using the Compton effect. The Compton effect allows higher imaging energies than that used for single photon emission computed tomography (SPECT). The Compton imaging system was constructed as a test platform, for example the scattering layer was assembled and then the trapper layer was mounted to the large frame. Electronics are connected to detect Compton-based events from the phantom's emissions. The Compton imaging system failed to address the design and constraint requirements for practical use in any commercial clinical setting. Current proposals lack the ability to integrate into imaging platforms in the clinic, or lack the design and constraint requirements (ie, flexibility and scalability) to address commercial and diagnostic needs. [0002] Compton cameras can have low sensitivity ($) and poor image quality (IQ). The absolute number of scattered photons in the scattering layer is low due to ge...
