Improved imaging devices and methods. A portable SPECT imaging device can be co-aligned with diagnostic imaging methods such as ultrasound. A gamma camera panel, including a gamma camera sensor, may be connected to a mechanical arm. A coded aperture mask is placed in front of the gamma-ray photon sensor and generated by scanning the patient from a reduced range in the direction around the patient and with a radiation sensor placed in close proximity to the patient. Obtain, which can be used to construct a high resolution three-dimensional map of the radioisotope distribution inside the patient. Increased image sensitivity and resolution are provided. SPECT imaging devices can be used to guide medical interventions such as biopsy and ablation therapy, and can also be used to guide surgery. |
