Cancer is a major public health problem worldwide. There are many types of cancer therapy methods including the radiotherapy. In radiotherapy, positioning the patient to a consistent treatment location is significantly crucial to receive an effective dose, which closely affects the success of the therapy. The most commonly used parameter for ensuring the effective patient position is the source to skin distance SSD . In this study, an infrared-based SSD measuring device is developed and its feasibility and accuracy are tested. The prototype of the infrared SSD measuring device IRD is composed of two major parts: a measuring distance sensor unit and a control unit. The microcontroller-based control unit displays the measurement in millimeters and transmits it to a computer via serial port. The SSD measurement experiments were conducted on a Siemens Primus Linear Accelerator with a full-sized male phantom. Thirty measurements were conducted at different gantry angles for anatomic locations in order to determine the mean values and standard deviations. This device was tuned by a conventional mechanical ruler with an accuracy of 0.7324 mm. The results revealed that the proposed device gives more consistent and accurate readouts with smaller variations in all body functions than other devices.

Kanser dünya genelindeki başlıca toplum sağlığı sorunudur. Radyoterapi de dahil olmak üzere birçok kanser tedavi yöntemi bulunmaktadır. Radyoterapide sabit bir tedavi noktasına hastayı konumlandırmak tedavinin başarımını doğrudan etkileyen etkin doz alımı için oldukça önemlidir. Etkili hasta konumunu garanti altına almak için en çok kullanılan parametre kaynak cilt mesafesidir SSD . Bu çalışmada, kızılötesi tabanlı bir SSD ölçüm cihazı geliştirilerek kullanışlılığı ve doğruluğu test edilmiştir. Kızılötesi SSD ölçüm cihazının IRD örneği iki ana bileşenden oluşmaktadır: bir mesafe algılayıcısı ve bir kontrol birimi. Mikrodenetleyici tabanlı kontrol birimi ölçümü milimetre cinsinden ekranda gösterir ve seri port aracılığıyla bir bilgisayara aktarmaktadır. SSD ölçüm deneyleri gerçek boyutlu bir erkek model üzerinde Siemens Primus marka lineer algılayıcı ile gerçekleştirilmiştir. Farklı cihaz açıları ve anatomik konumların her biri için otuzar ölçüm alınarak ortalama ve standart sapmalar hesaplanmıştır. Cihaz geleneksel mekanik cetvel ile 0,7324 mm doğrulukta kalibre edilmiştir. Elde edilen sonuçlara göre, geliştirilen cihaz tüm vücut konumları için benzerlerinden daha düşük sapmalarla daha yüksek doğrulukta ölçüm sonuçları vermektedir
