Therefore, the \u2018dose\u2019 of light that a patient receives during treatment is a clinically relevant quantity, with a minimum dose for effective treatment recommended in the literature. However, there are many different light measurement methods used in the published literature, which may lead to confusion surrounding reliable and traceable dose measurement in DPDT, and what the most appropriate method of light measurement in DPDT might be. Furthermore, for the majority of practitioners who do not carry out any formal dosimetry and for the patients receiving DPDT, building confidence in the evidence supporting this important treatment option is of key importance. This review seeks to clarify the methodology of DPDT and discusses the literature relating to DPDT dosimetry.<\/jats:p>","DOI":"10.3390\/ph12040143","type":"journal-article","created":{"date-parts":[[2019,9,20]],"date-time":"2019-09-20T10:48:14Z","timestamp":1568976494000},"page":"143","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Measuring Daylight: A Review of Dosimetry in Daylight Photodynamic Therapy"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3221-5105","authenticated-orcid":false,"given":"Paul","family":"O\u2019Mahoney","sequence":"first","affiliation":[{"name":"Photobiology Unit, NHS Tayside, Ninewells Hospital, Dundee DD1 9SY, UK"},{"name":"The Scottish Photodynamic Therapy Centre, Dundee DD1 9SY, UK"},{"name":"School of Medicine, University of Dundee, Dundee DD1 9SY, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Khazova","sequence":"additional","affiliation":[{"name":"Public Health England, Didcot OX11 0RQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7824-5580","authenticated-orcid":false,"given":"Ewan","family":"Eadie","sequence":"additional","affiliation":[{"name":"Photobiology Unit, NHS Tayside, Ninewells Hospital, Dundee DD1 9SY, UK"},{"name":"The Scottish Photodynamic Therapy Centre, Dundee DD1 9SY, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sally","family":"Ibbotson","sequence":"additional","affiliation":[{"name":"Photobiology Unit, NHS Tayside, Ninewells Hospital, Dundee DD1 9SY, UK"},{"name":"The Scottish Photodynamic Therapy Centre, Dundee DD1 9SY, UK"},{"name":"School of Medicine, University of Dundee, Dundee DD1 9SY, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"673","DOI":"10.1111\/j.1468-3083.2011.04386.x","article-title":"Daylight photodynamic therapy for actinic keratosis: An international consensus","volume":"26","author":"Wiegell","year":"2012","journal-title":"J.
