Abstract

A radiotherapy apparatus includes a source of radiation, a patient support for locating a patient in the field of the source of radiation, a position detector for determining a position of a patient relative to the radiotherapy apparatus, a comparator for comparing the output of the position detector with a predetermined position, and a feedback system for informing the patient of the output of the comparator.

Claims (13)

1. A radiotherapy apparatus, comprising:

a source of radiation;

a patient support for locating a patient in a field of the source of radiation;

a position detector configured to determine a position of the patient relative to the radiotherapy apparatus;

a comparator configured to compare an output of the position detector with a predetermined position; and

a feedback system configured to inform the patient of an output of the comparator,

wherein the output of the comparator includes a vector difference between the output of the position detector and the predetermined position, and the feedback system is configured to alert the patient as to a direction of the vector difference.

2. The radiotherapy apparatus according to claim 1 , wherein the feedback system comprises a visual display.

3. The radiotherapy apparatus according to claim 1 , wherein the feedback system comprises an audible signal.

4. The radiotherapy apparatus according to claim 1 , wherein the feedback system comprises a haptic response.

5. The radiotherapy apparatus according to claim 1 , wherein the position detector is configured to determine the position of the patient relative to a radiation focal point of the radiotherapy apparatus.

6. The radiotherapy apparatus according to claim 1 , wherein the feedback system is configured to alert the patient as to both the direction and a magnitude of the vector difference.

7. The radiotherapy apparatus according to claim 1 , further comprising a control system configured to monitor the output of the comparator and switch off the source of radiation when a magnitude of the output of the comparator is greater than a preset threshold.
