Purposes: This study aimed to develop and validate algorithms for automating intensity modulated radiation therapy (IMRT) planning in breast cancer patients, with a focus on patient anatomical characteristics.

Material And Methods: We retrospectively selected 400 breast cancer patients without lymph node involvement for automated treatment planning. Automation was achieved using the Eclipse Scripting Application Programming Interface (ESAPI) integrated into the Eclipse Treatment Planning System.

Purpose: The purpose of this study was to investigate the insertion of the plantaris tendon in terms of shape, length, width and size, to define if there is available bony insertion for future use as reconstructive procedure in secondary tendon graft in hand surgery.

Methods: In 30 limbs, the plantaris tendon was anatomically dissected to investigate its bony attachments to the calcaneus.

Results: The plantaris was present in 29 of 30 dissections and regularly inserted in the calcaneus.
