The goal of this study is to employ the autofluorescence nature of bacterial biofilms to guide the removal of these biofilms using a CAP scalpel. Pseudomonas fluorescens biofilms, which produce a green fluorescence under 405-nm UV light, were grown on 12 chicken samples.

The discharge voltage and current were 3.24 kV and 1.2 mA, respectively. Results based on analysis of the fluorescent images show that 97% biofilm removal; colony-forming unit analysis confirms that up to 99.98% of the bacteria are now absent from the tissue’s surface. This is the first instance of two new applications: 1) using CAP to remove bacterial biofilms from soft tissues and 2) employing CAP in an image-guided procedure.","PeriodicalId":46807,"journal":{"name":"IEEE Transactions on Radiation and Plasma Medical Sciences","volume":"8 8","pages":"990-996"},"PeriodicalIF":4.6,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142587632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many PET studies use the cerebellum as a reference region; therefore, AC methods should also be tested concerning their performance within the cerebellum. This study compares AC methods for PET/MR data, focusing on the cerebellum. Sixteen subjects underwent an [18F]FDG scan in a 3T-MR-BrainPET insert and a whole-head CT scan on the same day. The CT scan data were transformed into individual CT-based attenuation maps (AMCT), while the MR images were used to derive attenuation maps (AMs) using three methods: 1) Boston-MGH (AM textsubscript MGH); 2) London-UCL (AM textsubscript UCL); and 3) Juelich-Tx-template-based (AM textsubscript Tx-Juel). After reconstruction of the PET data with these four AMs, correlations, coefficients of determination, and relative errors (RErrs) between the PET-AM textsubscript CT and the other three PET-AMs were computed. The cerebellar RErr varied strongly between the three AC methods. The \u0000<inline-formula> <tex-math>${mathrm{ AM}}_{MGH}$ </tex-math></inline-formula>\u0000 method gave a RErr value of 3.85±5.03%, the AMUCL method gave 6.00±4.54%, and the AMTx-Juelgave 0.25±5.01%. Our results demonstrate that radiotracer uptake quantification in the cerebellum is sensitive to the applied PET AC. This dependency should be especially considered in neuroreceptor studies where the cerebellum is the reference region.","PeriodicalId":46807,"journal":{"name":"IEEE Transactions on Radiation and Plasma Medical Sciences","volume":"8 6","pages":"618-631"},"PeriodicalIF":4.6,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141500377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we present the software system for a dedicated brain PET scanner, encompassing data acquisition, detector calibration, sinogram generation, imaging reconstruction, and data correction. The dedicated brain PET scanner features 224 depth-encoding detectors, each with a depth of interaction (DOI) resolution of approximately 2 mm. The electronics and data acquisition system of the scanner can be configured in different modes for detector calibration or image acquisition. Procedures for obtaining detector calibration parameters, including crystal look-up tables (LUTs), crystal depth-of-interaction LUTs, crystal energy, and timing calibration parameters, were developed. A novel virtual crystal-based sinogram generation method was developed to reduce sinogram size while preserving positioning accuracy. We also introduced a graphics processing unit-accelerated ordered subset expectation maximization imaging reconstruction method. The spatial resolution of the scanner was assessed using a point source at both the center and 1/4 axial field of view with varying radial offsets. We measured singles and prompt count rates at different activities using a monkey-sized phantom. Furthermore, we conducted scans on a 3-D Hoffman brain phantom and a rabbit, demonstrated the imaging capabilities of the PET scanner.","PeriodicalId":46807,"journal":{"name":"IEEE Transactions on Radiation and Plasma Medical Sciences","volume":"8 6","pages":"655-663"},"PeriodicalIF":4.6,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141500388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our motivation is to design a TB-PET system with up to 70 cm axial coverage that mitigates the parallax error degradation by using a detector concept based on semi-monolithic LYSO crystals. Furthermore, this detector approach allows to simultaneously reach an accurate coincidence time resolution (CTR) to enhance the image quality by means of time-of-flight (TOF) reconstruction algorithms. We have simulated and compared two positron emission tomography (PET) prototypes with about 70 cm but a different number of detector rings (7 versus 5). The NEMA NU 2 2018 protocol has been implemented. By correcting the parallax error with the depth-of-interaction (DOI) information, the spatial resolution remains homogeneous and below 3 mm in the entire field of view (FOV), differently from designs based on pixelated crystals. The sensitivity reaches values of 58 and 115 cps/kBq, for the 5 and 7 rings configurations, respectively. The noise equivalent count rate (NECR) was found at 563 kcps/mL. This value is lower than other systems, most likely due to the requirement to process a larger number of channels to characterize the DOI. Percent contrasts obtained for two different phantoms are in general beyond 80% for the largest spheres, nearly 100% for the 7 rings configuration once TOF is applied during the reconstruction process. In conclusion, although the sensitivity and NECR results for the 5-rings configuration are lower compared to the 7-rings approach, its overall performance is enhanced by the addition of TOF and parallax error correction, improving that of conventional Whole Body PET scanners (axial length: 20–30 cm) in terms of image quality.","PeriodicalId":46807,"journal":{"name":"IEEE Transactions on Radiation and Plasma Medical Sciences","volume":"8 6","pages":"690-699"},"PeriodicalIF":4.6,"publicationDate":"2024-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10436427","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141500251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both arrays had the same 1.1 mm pitch but utilized different reflectors—barium sulfate (BaSO4) and enhanced specular reflector film (ESR)—for high-resolution PET applications.

The lateral surfaces of the BGO elements were unpolished (saw-cut), while the two ends were polished. Flood histograms showed that the detector based on the BGO array with BaSO4 reflector had much better crystal identification and depth-of-interaction (DOI) resolution. Specifically, the energy, DOI, and timing resolutions for the detector using the BGO array with BaSO4 reflector were 19.8 ± 1.5%, 4.13 ± 0.48 mm, and 2.80 ± 0.23 ns, respectively.
