“…The main reasons for fast SPECT acquisition are to reduce the high incidence of artifacts caused by poor patient compliance during acquisition and to increase patient throughput in busy nuclear medicine departments. Therefore, the RR OSEM modality is the most important factor for producing images with higher spatial resolution and signal-to-noise ratio (SNR) than in conventional SPECT (8) .…”

Background: The use of resolution recovery (RR) in bone and myocardial perfusion imaging is becoming increasingly popular in nuclear medicine departments. RR produces reconstructed images that show improved spatial resolution and signal-to-noise ratio compared with conventional single-photon emission computed tomography (SPECT) images. Objective: To evaluate the impact of the ordered subset expectation maximization (OSEM) RR modality on preserving noise, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) for short SPECT acquisition. Methods: This prospective study was conducted on 80 patients. Full SPECT acquisition was performed as a standardized protocol, while reduced acquisition was achieved with the Poisson resampling method. Noise, SNR, and CNR were measured for different reconstruction parameters for the same image levels. The impact of surface area and body mass index was also measured for the same reconstruction parameters. Results: The results show significantly higher SNR and CNR for the Evolution for Bone protocol compared to the other two reconstruction protocols for full and reduced SPECT acquisition. With the shortening of the SPECT acquisition, an increase in the value of noise was recorded. SNR and CNR decreased with the reduction in SPECT acquisition. Conclusion: The Evolution for Bone protocol for all three analyzed acquisition protocols had the lowest noise values. The highest SNR and CNR were recorded in the Evolution for Bone protocol for the three acquisition protocols and SPECT acquisition time can be reduced from 20 to 10 min for bone SPECT.

“…Approaches using medical X-ray tomography are very effective for 3D-reconstruction of tissues/organs [8]. We can also highlight some areas that are associated with the localization of implanted biomaterials [8,26], the colonoscopy, the ultrasonic sounding [9], the stereoscopic fluorescence imaging, the multispectral magnetic resonance image analysis [16], the single photon emission computed tomography (CT) [11], the electron tomography [6], the use of combined methods [9]. The transition begins from micro-CT to nano-CT [8,20].…”

Abstract.A software for processing sets of full-color images of biological tissue histological sections is developed. We used histological sections obtained by the method of high-precision layer-by-layer grinding of frozen biological tissues. The software allows restoring the image of the tissue for an arbitrary cross-section of the tissue sample. Thus, our method is designed to create a full-color 3D reconstruction of the biological tissue structure. The resolution of 3D reconstruction is determined by the quality of the initial histological sections. The newly developed technology available to us provides a resolution of up to 5 -10 µm in three dimensions.
