We build hope for everyone dealing with Cancer.\nElekta is shaping the standard of care, together with healthcare providers, by developing precision radiation medicine that brings advanced radiotherapy into routine clinical practice. Our solutions support consistent, efficient and personalized care, addressing evolving patient needs. Through adaptive radiotherapy, precision treatment delivery and integrated workflows, Elekta supports care teams across a range of clinical settings. Each year more than 2 million patients are treated using Elekta solutions across over 130 countries. Elekta is headquartered in Stockholm, Sweden, with over 4,000 employees and offices in more than 40 countries. The company is listed on Nasdaq Stockholm. For more information, visit elekta.com.\nIntroduction\nLeksell Gamma Plan (LGP) is a successful treatment planning system for stereotactic neuro radiotherapy performed by the Leksell Gamma Knife. Both are made by Elekta in Stockholm.\nLGP is used by neurosurgeons and radio oncologists worldwide to analyse brain imaging and identify targets and choose doses of gamma radiation, as well as planning the application of the required doses to these targets by the Leksell Gamma Knife over a series of one or more treatment fractions.\nBackground\nAn important step in each treatment is correctly determining the position of structures shown in CT/MR brain imaging in a co-ordinate system relative to the machine. A mechanical frame with fiducial marks is firmly attached to the patient’s head prior to imaging, and the marks are visible in the resulting images. The frame is firmly attached to the Gamma Knife during treatment, allowing the correct calculation of positions of structures in the brain in a known co-ordinate system (calculation of the transformation from image co-ordinates to machine co-ordinates is known as registration).\nProblem Statement\nPresent image registration algorithm for tomographic (MR/CT) images is semi-automatic and we would like to automate it and see if better registration transforms can be found.\nOutput\nThis thesis project aims to:\na) Propose and prototype method(s) for fully automatic detection of fiducial marks in MR/CT images.\nb) Propose and prototype method(s) for fully automatic image registration based on fiducials.\nc) Propose relevant metric(s) for quality assurance (e.g. mean and max errors).\nd) Evaluate robustness and accuracy for proposed method(s) compared to current fiducial based\nregistration in LGP (for >100 representative and varying cases).\nWho are we looking for?\nMasters student, probably specialized in image handling/graphics.\nNo prior knowledge of Gamma Knife treatment planning is required. Domain experts from Elekta will provide introductions to the relevant aspects of the software architecture and workflow. The student will work closely with experts in software development and clinical applications throughout the project.\nPracticalities\nLocation: Elekta office, Stockholm\nSupervisor: Ethan Palmiere, \nStart date: Early 2027","description_format":"text","description_chars":3202,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Surgical Instruments & Devices","Medical Imaging Systems","EHR & Clinical Software"],"lifecycle":[{"event":"open","at":"2026-10-23T08:34:05Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.63,"p_room":1,"age_days":10,"expected_fill_days":56,"reasons":["conf:11","stale_co","velocity","win:early"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/elekta-master-thesis-automatic-ctmr-image-registration","json_url":"https://alion.io/job/elekta-master-thesis-automatic-ctmr-image-registration.json","meta":{"generated_at":"2026-11-02T03:10:56Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":4760,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":1801963},"rest":"https://alion.io/mcp/rest/get_company?id=1801963"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Felekta-master-thesis-automatic-ctmr-image-registration"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Felekta-master-thesis-automatic-ctmr-image-registration"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Felekta-master-thesis-automatic-ctmr-image-registration"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/elekta-master-thesis-automatic-ctmr-image-registration\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Felekta-master-thesis-automatic-ctmr-image-registration"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3141266}},{"tool":"search_jobs","arguments":{"company":"elekta.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3141266},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
