Medical device for radiotherapy and method of manufacturing the same

Patient positioning device for use in a radiotherapy treatment process comprising:

• a positioning board, and
• a positioning and shaping shell manufactured by i) positioning and supporting a target body portion with a transparent body shaper in a predetermined position on a positioning board, the positioning board presenting at least one transparent portion permitting scanning through it, ii) at least partially imaging a target body portion surface via the transparent portion of the positioning board and said transparent body shaper, iii) processing acquired image data in a processing unit to generate processed image data, and iv) producing a 3D positioning and shaping shell model via additive or subtractive manufacturing method based in the processed image data and reproducing a patient's target body portion shape and adapted to be installed on the positioning board so as to receive and immobilize said target body portion.
