When using radiotherapy to treat tumors, physicians harness the destructive power of the radiation to kill the cancer cells in a targeted manner, thereby contributing to the curing of cancer patients. The aim is to destroy the whole tumor region while minimizing damage to healthy tissue\u00a0\u2014 a delicate balance that requires the utmost precision. The success of the treatment largely depends on this level of precision and so medical staff generate an accurate image of the tumor beforehand using radiation-based computed tomography and then plan the treatment using these scans. When the radiotherapy takes place a few days later, the patient must be in the exact same position as they were for the initial examination. This position must not change during the therapy, wrties Fraunhofer Insititute in a press release<\/a>.<\/p>\n\n\n\n

The novel system developed by Fraunhofer researchers can continuously monitor the position of the patient both before and during radiation therapy. The chances of successful treatment and subsequent recovery are therefore significantly higher. In other words: it is a vital contribution to more effective cancer treatment that is gentler on the body. Dr. Peter K\u00fchmstedt, Dr. Christoph Munkelt and Matthias Heinze from Fraunhofer IOF were awarded the 2022 Joseph von Fraunhofer Prize for the overall system, which was developed in collaboration with Varian Medical Systems and is production-ready. What particularly stood out to the jury was the relief provided to cancer patients who undergo this treatment.<\/p>\n\n\n\n

High-frequency frame rate and accurate to less than half a millimeter<\/strong><\/h3>\n\n\n\n

\u201cThe system produces 3D images of the patient before and during radiotherapy with an accuracy of less than half a millimeter and a high-frequency frame rate\u00a0\u2014 that is unique,\u201d emphasizes Munkelt. \u201cThis enables physicians to monitor the optimum alignment of the rays with minimum additional radiation exposure from imaging X-ray systems. Optical systems also allow for precise monitoring of patient positioning for high-dose radiation with fewer treatment sessions. The treatments are very effective and also reduce physical and mental stress.\u201d During the initial examination using computed tomography, an optical sensor projects a variable infrared pattern\u00a0\u2014 invisible to the human eye\u00a0\u2014 onto the body, which is then recorded by two cameras. Patients, who are already under a lot of emotional stress due to their illness, are not additionally irritated by the light\u00a0\u2014 another advantage. Based on these images, the system generates a 3D model that is later used to arrange the relevant body parts\u00a0\u2014 an irradiated body area of approximately 30 x 30 cm\u00a0\u2014 in exactly the same position as they were for the preliminary examination.<\/p>\n\n\n

Improved safety<\/h3>\n\n\n\n

A further advantage here is that if the patient moves during treatment, either because they are breathing heavily or making compensatory movements, the irradiated body area consequently changes. In this respect, the system guarantees more safety: If the patient\u2019s position changes, the system immediately registers this and turns the radiation off as a precaution. Going forward, smaller movements, e.g., due to breathing, can be adapted and the radiation adjusted live. Even more challenging radiation therapies for tumors that are difficult to trace, such as those in the abdominal region, should become possible in the future.<\/p>\n\n\n\n

The team of researchers had to overcome numerous challenges for this development. \u201cThe focus of the development was transferring the entire package as a methodology into an industrial solution and designing a sensor network,\u201d explains Heinze. In the long term, the world market leader Varian Medical Systems expects the novel system to be distributed around the globe for patient position monitoring.<\/p>\n","protected":false},"author":2084,"featured_media":511132,"template":"","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[34665],"tags":[30764,6516,32744,127778],"location":[24456],"internal_archives":[],"class_list":["post-375109","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-health","tag-cancer-treatment","tag-fraunhofer","tag-radiotherapy","tag-varian-medical-system","location-germany"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2022\/03\/ocnNTBLZ-Pathway-Testing_TMZ-18-scaled.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/mauro-mereu\/","display_name":"Mauro Mereu"},"relative_dates":{"created":"Posted 4 years ago","modified":"Updated 4 years ago"},"absolute_dates":{"created":"Posted on May 20, 2022","modified":"Updated on May 20, 2022"},"absolute_dates_time":{"created":"Posted on May 20, 2022 11:00 am","modified":"Updated on May 20, 2022 11:00 am"},"featured_img_caption":"","tax_additional":{"category":{"linked":["Health<\/a>"],"unlinked":["Health<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["cancer treatment<\/a>","Fraunhofer<\/a>","radiotherapy<\/a>","Varian Medical System<\/a>"],"unlinked":["cancer treatment<\/span>","Fraunhofer<\/span>","radiotherapy<\/span>","Varian Medical System<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["EN<\/a>"],"unlinked":["EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":["pll_628749dbf1e7e<\/a>"],"unlinked":["pll_628749dbf1e7e<\/span>"],"slug":"post_translations","name":""},"location":{"linked":["Germany<\/a>"],"unlinked":["Germany<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/375109","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/2084"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/511132"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=375109"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=375109"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=375109"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=375109"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=375109"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
