RapidArc | Image Gallery

The RapidArc® technology image gallery contains treatment planning images for many different clinical cases. Individual images may be enlarged by double clicking on the image, opening in a separate browser window. The RapidArc cases can be filtered by treatment site or viewed as an entire library using the "Display All" selection in the drop down menu. Descriptions of the images are presented when the mouse cursor is placed over the images, or when the images are enlarged.

Filter:

Adenocarcinoma of the Right Upper Lung

Patient treated with one RapidArc arc with 10MV energy with 688MU. Total dose 3000cGy and daily dose 300cGy.

This patient had a fixed node in the supraclavicular area that needed radiation therapy. The patient also had previous lung radiotherapy, so the critical structures were of particular concern. Therefore, a RapidArc treatment was the best option to achieve coverage and spare critical structures.

Basal Cell Carcinoma with Muscle Invasion

Patient treated with two RapidArc arcs with 6MV energy and 561MU total. Total dose 6600cGy and daily dose 200cGy.

Basal cell carcinoma invaded the muscle. Critical organ for this case is the spinal cord. A bolus was used to move the high dose away from the spinal cord and improve target coverage.

Sagital view showing spinal cord sparing. Transversal view showing spinal cord sparing. Two coplanar arcs were used to achieve spinal cord sparing

Spindle Cell Sarcoma of the Scalp

Patient was treated with two RapidArc arcs with 6MV energy and 585MU total. Total dose 5940cGy and daily dose 180cGy.

A bolus was used to bring up the high dose to the scalp; this RapidArc plan provided better dose distribution than a typical electron plan.

Three orthogonal views and a 3D model view displaying the bolus and the high dose on the scalp Donut shaped dose distribution covering the scalp with normal tissue sparing Two coplanar arcs with HD 120(TM) MLC were used to create highly concave dose distribution.

Lung Metastases

Patient was treated with two RapidArc arcs with 6MV energy and 2539MU total. Total dose 4000cGy and daily dose 800cGy.

The spine and esophagus were of great concern. Each PTV had a 30cc volume.

Transversal view displaying the bilateral metastases, each with volume of 30cc. Two coplanar arcs with gantry rotation from 5 to 355 degrees helped to avoid the spinal cord.

Malignant Neoplasm of the Peritoneum

Patient treated with two RapidArc arcs with 10MV energy and 383MU total. Total dose 4500cGy and daily dose 180cGy.

A RapidArc plan was chosen vs. a two or four field plan because of the location of the tumor. Critical structures were both right and left kidneys, spinal cord, and the bowel. The dose needed was achieved, while sparing the organs at risk by using RapidArc.

Adenocarcinoma of the Prostate

Patient treated with two RapidArc arcs with 6MV energy and 607MU total. Total dose 7560cGy and daily dose 180cGy.

The critical structures of concern were the bladder, rectum and both femoral heads. A RapidArc conforms to the PTV while maintaining doses at a minimum to the critical structures.

Metastatic Renal Cell Carcinoma - Paraspinal and Rib Mass

Patient treated with two RapidArc arcs with 10MV energy and 615MU total. Total dose 3000cGy and daily dose 300cGy.

For this particular patient the best option was a double RapidArc to avoid overdosing the spinal cord and the left lung. Other critical structures used in the optimization were the heart, both right and left kidneys and the total lung volumes.

Multiple Brain Metastases

Patient treated with two RapidArc arcs with a total of 1955MU. Total dose 21Gy in 3 fractions.

This patient had a primary lung tumor with 7 brain metastases with volumes ranging from 0.7 to 25 cubic centimeters.
