Patent number: 10631808Abstract: A biomarker of lung condition can conventionally be obtained using a spirometer. A spirometer provides an estimate of the volume of air expelled by the lungs. This is a rather indirect biomarker of the staging of a lung condition, because a reduction in lung volume may only manifest itself at a point where symptoms are well advanced. A lung condition such as Chronic Obstructive Pulmonary Disorder (COPD) is typically not visible on conventional X-ray attenuation images, because the relevant tissue (alveoli-bearing microstructured lung tissue) contains a lot of air. The X-ray dark-field can successfully indicate microstructure, such as lung alveoli. Therefore, imaging the lungs using the dark-field can provide information on the status of COPD.Type: GrantFiled: September 30, 2016Date of Patent: April 28, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Roland Proksa, Jens Von Berg

Patent number: 10441819Abstract: Embodiments of the present disclosure provide improved techniques for dosimetry in radiotherapy treatment. In a fractionated radiotherapy treatment, once the first fraction is complete and has been verified, data is generated which is representative of the dose development during delivery of the treatment for that patient and that treatment plan. This data can be used as a comparator for the instantaneous doses observed during subsequent fractions, allowing real-time dosimetry verification for the second and subsequent fractions after a successful first fraction.Type: GrantFiled: June 10, 2016Date of Patent: October 15, 2019Assignee: ELEKTA LIMITEDInventor: Abdul Sayeed
