Virtual-pinhole PET.
Tai YC, Wu H, Pal D, O'Sullivan JA. Tai YC, et al. J Nucl Med. 2008 Mar;49(3):471-9. doi: 10.2967/jnumed.107.043034. Epub 2008 Feb 20. J Nucl Med. 2008. PMID: 18287272 Free PMC article.
We proposed and tested a novel geometry for PET system design analogous to pinhole SPECT called the virtual-pinhole PET (VP-PET) geometry to determine whether it could provide high-resolution images. ...

Results of the Pinhole Test Correlate with Hybrid Contact Lens Visual Acuity in Patients with Visual Impairment due to Corneal Diseases.
Kanclerz P. Kanclerz P. J Ophthalmol. 2022 Jun 24;2022:4932856. doi: 10.1155/2022/4932856. eCollection 2022. J Ophthalmol. 2022. PMID: 35783341 Free PMC article.
The improvement in the pinhole test over corrected distance VA was moderately correlated with the improvement with the fitted lens over corrected distance VA (r = 0.6269; 95% confidence interval (CI): 0.32-0.80; p=0.0005). CONCLUSIONS: A significant improvement in V …

HUBBARD WC, HUBBARD WB. HUBBARD WC, et al. Trans Am Acad Ophthalmol Otolaryngol. 1964 Sep-Oct;68:914. Trans Am Acad Ophthalmol Otolaryngol. 1964. PMID: 14211261 No abstract available.
Adaptive SPECT.
Barrett HH, Furenlid LR, Freed M, Hesterman JY, Kupinski MA, Clarkson E, Whitaker MK. Barrett HH, et al. IEEE Trans Med Imaging. 2008 Jun;27(6):775-88. doi: 10.1109/TMI.2007.913241. IEEE Trans Med Imaging. 2008. PMID: 18541485 Free PMC article.
Adaptive imaging systems alter their data-acquisition configuration or protocol in response to the image information received. An adaptive pinhole single-photon emission computed tomography (SPECT) system might acquire an initial scout image to obtain preliminary informati …

Study of luminance effects on pinhole test results for visually impaired patients.
Eagan SM, Jacobs RJ, Demers-Turco PL. Eagan SM, et al. Optom Vis Sci. 1999 Jan;76(1):50-8. doi: 10.1097/00006324-199901000-00028. Optom Vis Sci. 1999. PMID: 10030615
Pinhole test results were enormously variable, underestimating and overestimating postrefraction visual acuity. The pinhole test was less reliable when improvements in postrefraction visual acuity were small. ...

Multi-pinhole collimator design in different numbers of projections for brain SPECT.
Huang W, Mok GSP. Huang W, et al. Front Med (Lausanne). 2023 Sep 28;10:1211726. doi: 10.3389/fmed.2023.1211726. eCollection 2023. Front Med (Lausanne). 2023. PMID: 37841005 Free PMC article.
In this study, we aim to evaluate the impact of varying the number of pinholes and the number of projections on the performance of MPH brain SPECT. METHODS: The system design was based on a commercial clinical dual-head SPECT/CT scanner, with target spatial resoluti …
